Description

The present invention relates to a procurement management system that selects two or more suppliers from multiple suppliers as a supply supplier group, a computer program for the procurement management system, and a control method for the procurement management system.

As a procurement-related technology, for example, Patent Document 1 discloses a procurement network in which a seller pools its inventory with other sellers that use the same procurement network. Specifically, a seller requests that at least a portion of its inventory of an item be pooled into a common inventory pool. Then, if the item is determined to be of the same type or quality as the same item pooled by the other seller, the seller's inventory is pooled into the common inventory pool. Subsequently, inventory credits are provided to sellers of the pooled inventory.

Patent Document 2 also discloses a supply chain design plan generation unit that generates a supply chain design plan for a specified item. Specifically, the supply chain design plan generation unit extracts records that match the item to be produced or procured. The supply chain design plan generation unit then extracts multiple factories and multiple suppliers corresponding to the records. The supply chain design plan generation unit then generates multiple patterns of supply chain design plans that include the selected factory, and multiple patterns of supply chain design plans that include the selected supplier. Furthermore, the supply chain design plan generation unit evaluates whether the generated supply chain design plans can meet delivery deadlines, and excludes design plans that cannot meet delivery deadlines from the supply chain design plans.

Special Publication No. 2014-503924 Japanese Patent Application Laid-Open No. 2021-5186

A user may wish to purchase a quantity of an item that exceeds the supply amount that a single supplier can provide. In this case, if the user orders a quantity of an item that exceeds the supply amount, the period from order to delivery of the item will be longer. In other words, the supplier will need to take longer than the normal delivery time to supply a quantity of an item that exceeds the supply amount.

A procurement management system according to one aspect of the present invention includes an acquisition means for acquiring request conditions including a requested quantity and delivery date of an item requested by a user and supply conditions including the supply amount of the item from each of a plurality of suppliers that can supply the item; a determination means for determining whether allocation conditions for allocating the requested quantity of the item to two or more of the plurality of suppliers are met based on the request conditions and the supply conditions; a selection means for selecting one supplier from the plurality of suppliers if the allocation conditions are not met, and selecting two or more suppliers from the plurality of suppliers as a supply supplier group if the allocation conditions are met; an ordering means for ordering the item from the selected one supplier or the selected supply supplier group; and a system for ordering the item to the user. and a presentation means for presenting sales order information corresponding to the selected supplier, wherein when an obstructing condition occurs that prevents the supply of the goods by the delivery date for the selected supplier or a faulty supplier that is at least one supplier in the selected group of suppliers, the selection means selects from the multiple suppliers at least one alternative supplier that can supply the goods in the quantity that was ordered from the faulty supplier, the ordering means cancels the order with the faulty supplier and places an order for the goods in the quantity that was ordered from the faulty supplier with the alternative supplier, and the presentation means maintains the presentation of the sales order information as is if the change condition for the sales order information is not met, and presents changes to the sales order information to the user if the change condition for the sales order information is met.

In another aspect of the present invention, a computer program for a procurement management system includes a computer, and causes the computer to acquire request conditions including a requested quantity and delivery date of an item requested by a user and supply conditions including the supply amount of the item from each of a plurality of suppliers that can supply the item, determine whether or not allocation conditions for allocating the requested quantity of the item to two or more suppliers from the plurality of suppliers are satisfied based on the request conditions and the supply conditions, select one supplier from the plurality of suppliers if the allocation conditions are not satisfied, and select two or more suppliers from the plurality of suppliers as a supply supplier group if the allocation conditions are satisfied, and The system causes the group of supply suppliers to place an order for the goods, and presents sales order information corresponding to the order for the goods to the user. If an obstructing condition occurs that prevents the selected supplier or at least one supplier in the selected group of supply suppliers from supplying the goods by the delivery date, the system selects from among the multiple suppliers at least one alternative supplier that can supply the goods in the quantity that was ordered from the obstructed supplier, cancels the order with the obstructed supplier, and orders the goods in the quantity that was ordered from the obstructed supplier from the alternative supplier. If the conditions for changing the sales order information are not met, the system maintains the presentation of the sales order information as is, and if the conditions for changing the sales order information are met, changes to the sales order information are presented to the user.

Furthermore, a control method for a procurement management system according to another aspect of the present invention is a control method for a procurement management system equipped with a computer, which causes the computer to acquire request conditions including a requested quantity and delivery date of an item requested by a user and supply conditions including the supply amount of the item from each of a plurality of suppliers that can supply the item, determines whether or not an allocation condition for allocating the requested quantity of the item to two or more suppliers from the plurality of suppliers is satisfied based on the request conditions and the supply conditions, selects one supplier from the plurality of suppliers if the allocation condition is not satisfied, and selects two or more suppliers from the plurality of suppliers as a supply supplier group if the allocation condition is satisfied, and The system causes the system to order the items from a group of suppliers, presents sales order information corresponding to the order for the items to the user, and if an obstructing condition occurs that prevents the selected supplier or at least one supplier from the selected group of suppliers from supplying the items by the delivery date, selects from among the multiple suppliers at least one alternative supplier that can supply the items in the quantity that was ordered from the obstructed supplier, cancels the order with the obstructed supplier, and orders the items in the quantity that was ordered from the obstructed supplier from the alternative supplier, maintains the presentation of the sales order information as is if the change conditions for the sales order information are not met, and presents changes to the sales order information to the user if the change conditions for the sales order information are met.

This helps prevent the burden on users from increasing when placing orders with alternative suppliers.

Below, exemplary embodiments for carrying out the present invention will be described in detail with reference to the drawings. However, the dimensions, materials, shapes, and relative positions of components described in the following embodiments can be set arbitrarily and can be changed depending on the configuration of the device to which the present invention is applied or various conditions. Furthermore, unless otherwise specified, the scope of the present invention is not limited to the embodiments specifically described below.

[First embodiment]
FIG. 1 shows a sales management system 100 equipped with a procurement management system that selects two or more suppliers from multiple suppliers as a supply supplier group. As an example, a supplier is a supplier that produces, processes, sells, transports, or stores goods in order to supply them. A single supplier may also own multiple warehouses or production sites for goods as multiple suppliers. The sales management system 100 includes a user terminal 40 managed by a user, an inventory management server 10 and a procurement management server 20 managed by a management company such as a distributor, and a supplier terminal 60 managed by a supplier. For example, a user purchases goods as merchandise from a distributor. The distributor then procures the goods from the supplier and sells them to the user. The supplier also supplies the goods to the distributor.

The sales management system 100 is configured as a network system or client-server system equipped with a procurement management system including a procurement management server 20 and an inventory management server 10. For example, a seller manages the inventory management server 10 and the procurement management server 20 and sells products in response to user requests. The procurement management server 20 functions as a server device and is configured as a single logical server device, for example, by combining multiple server units 21 as computer devices. The inventory management server 10 also functions as a server device and is configured as a single logical server device, for example, by combining multiple server units 11 as computer devices. However, the procurement management server 20 may be configured as a single server unit 21, or the inventory management server 10 may be configured as a single server unit 11. Alternatively, the procurement management server 20 and the inventory management server 10 may be configured logically using cloud computing.

The procurement management server 20 provides various services, including an ordering service for goods, to the user terminal 40 or to the user of the user terminal 40. This ordering service includes a distribution service that distributes programs or data to the user terminal 40 via the network 50, and a storage service that stores data received from the user terminal 40. The distribution service is, for example, a service that distributes data for updates.

The inventory management server 10, an example of a supply quantity management server, stores and manages supply conditions including the supply quantity of items. For example, the inventory management server 10 receives from the supplier terminal 60 the inventory quantity of each item from multiple suppliers as a supply quantity, which is an example of a supply condition. The inventory management server 10 also receives from the supplier terminal 60 the supply time for each of the multiple suppliers to supply items, as another example of a supply condition. The inventory management server 10 then stores the inventory quantity for each item in association with supplier identification information that identifies each supplier. The inventory management server 10 may also store and manage supply conditions including the supply quantity of items stored by a retailer. Note that an item may be a finished product with a single integrated function, or may be a single item or assembly consisting of multiple parts that is incorporated into a finished product. Furthermore, items include units, jigs, devices, and equipment that combine multiple parts.

For example, the supply time may be the shipping date of the item, the arrival date when the item reaches the user, the production completion date of the item, the processing completion date of the item, or the arrival date when the item reaches the logistics center. These supply times are specific dates or times, but the supply time may be any information that can identify the timing of the supply of the item, and may be the length of time required for shipping, arrival, or completion, or the length of time required for transportation. Furthermore, the supply quantity is the amount of item that can be supplied to the user, and may be the production volume, processing volume, or shipping volume of the supplier at a specified supply time. Furthermore, both the supply time and supply quantity may be calculated or predicted by the inventory management server 10.

The user of the supplier terminal 60 sends the supply conditions to the inventory management server 10 via email or other means at any time (e.g., at a specified time, once a day, once a week, or four times a day). Alternatively, the supplier terminal 60 may send the supply conditions automatically at a specified time. The supplier terminal 60 may also send the supply conditions in response to a request from the inventory management server 10. For example, when a user inputs the requested quantity of an item, the inventory management server 10 requests the supplier terminal 60 to send the supply conditions in response to the input. Furthermore, the administrator of the inventory management server 10 may obtain the supply conditions from each supplier via telephone, facsimile, or other means. In this case, the administrator may manually enter the obtained supply conditions into the inventory management server 10. Furthermore, the inventory management server 10 may obtain the supply conditions from an external database, such as an inventory quantity database. The inventory management server 10 may also calculate or predict the supply conditions.

The supply conditions may include the quantity of goods that can be supplied within a specified period, such as inventory quantity, and this quantity may be zero or the quantity of goods that can be produced within the specified period. The supply conditions may also include information related to the goods, such as the name, model number, location of origin, supply availability period, unit price, transportation costs, specifications, manufacturing conditions, or processing conditions. Furthermore, the supply conditions may also include information such as the supplier's name, supplier identification information, or location. The following mainly describes the case where the supply condition is inventory quantity.

The user terminal 40 and the supplier terminal 60 are computer devices that can be connected to a network. For example, the user terminal 40 includes a desktop or notebook personal computer 41 and a portable tablet terminal device 42. The supplier terminal 60 also includes a desktop or notebook personal computer 61 and a portable tablet terminal device 62. Additionally, the user terminal 40 and the supplier terminal 60 include mobile terminal devices such as mobile phones (including smartphones). By implementing various computer programs, the user terminal 40 and the supplier terminal 60 can allow users to enjoy various services provided by the procurement management server 20. By implementing various computer programs, the supplier terminal 60 may also allow suppliers to enjoy various services provided by the inventory management server 10.

The user terminal 40 and supplier terminal 60 can be connected to the procurement management server 20 via a specified network 50. The supplier terminal 60 can be connected to the procurement management server 20 and inventory management server 10 via a specified network 50. The following describes the case where the user terminal 40 is a personal computer 41 and the supplier terminal 60 is a personal computer 61.

Network 50 is configured to connect user terminals 40 and supplier terminals 60 to procurement management server 20, and to connect supplier terminals 60 to inventory management server 10. Network 50 is configured to enable network communication using the TCP/IP protocol. Specifically, LAN (Local Area Network) 52 connects procurement management server 20 and inventory management server 10 to Internet 51. The Internet 51, which serves as a WAN (Wide Area Network), is connected to LAN 52 via router 53. Network 50 may be a dedicated line, telephone line, corporate network, mobile communications network, other communication line, or a combination thereof, and may be wired or wireless. User terminals 40 and supplier terminals 60 are also configured to be connected to Internet 51. Alternatively, server unit 21 of procurement management server 20 and server unit 11 of inventory management server 10 may be interconnected via Internet 51 instead of or in addition to LAN 52.

The procurement management server 20 functions as a web server that displays various web pages on the display unit of the user terminal 40 in response to access from the user terminal 40. In addition, in response to an order placed by a user, the procurement management server 20 performs processes such as arranging for the ordered items, issuing transportation instructions, and invoicing the purchase price.

Specifically, procurement management in the sales management system 100 will be described with reference to Figure 2. The supplier terminal 60 includes terminals for each of multiple suppliers, and in the example of Figure 2, includes a terminal for supplier A and a terminal for supplier B. Each supplier terminal 60 transmits supply conditions, including inventory amounts, to the inventory management server 10 at any time. The inventory management control unit 13 then associates the received inventory amounts with the respective supplier identification information for each item and stores them in the inventory management memory 12.

A user wishing to purchase an item accesses a website provided by the procurement management server 20 from a user terminal 40. The user then inputs the desired quantity of the item via the website as an example of a required condition. The user also inputs a delivery date for the item requested by the user as another example of a required condition. The required conditions may include information related to the item, such as the name, model number, shipping location, desired price, specifications, manufacturing conditions, processing conditions, or drawings. Alternatively, the required conditions may be included in a purchase order requesting the purchase of the item. In this case, when the user performs an operation to place a purchase order, the required conditions are transmitted from the user terminal 40 to the procurement management server 20. The required conditions may also be included in a request for quotation, which requests an estimate for at least one of the price and delivery date of the item. In this case, when the user performs an operation to request a quotation, the required conditions are transmitted from the user terminal 40 to the procurement management server 20. As an example, the delivery date is information indicating the time that serves as the basis for receiving the item, such as the time of shipment, arrival, or completion of production of the item.

The server control unit 23 of the procurement management server 20 acquires the input requirements and stores them in the server memory 22 of the procurement management server 20. Furthermore, the server control unit 23 acquires inventory information from the inventory management server 10 and selects a supplier that can supply the requested items. If the inventory of one specific supplier is sufficient to meet the requested quantity, the server control unit 23 selects that specific supplier. The server control unit 23 then notifies the user that a purchase order is possible by notifying them of the quantity they wish to purchase. The user confirms the quantity and performs an operation to place the purchase order. Alternatively, the server control unit 23 may notify the user that a purchase order is possible by enabling an operation to place a purchase order, such as by displaying a specified button. For example, a purchase order includes information indicating a model number that identifies the item, the desired delivery date for the item, the quantity of the item, and the shipping destination for the item. Alternatively, if the purchasing company has stored the item procured from the specific supplier and the inventory is sufficient to meet the requested quantity, the server control unit 23 may notify the user that a purchase order is possible. For example, a distributor may sell to a user items that it procures from a supplier and stores in its own inventory.

The server control unit 23 then accepts the purchase order and creates a sales order corresponding to the accepted purchase order. Furthermore, the server control unit 23 creates a purchase order linked to sales identification information (e.g., a sales order number) that identifies the sales order. The server control unit 23 then transmits the purchase order to the supplier terminal 60 of the specified supplier. For example, the purchase order includes information indicating the model number that identifies the item, the shipping date of the item, the quantity of the item, and the destination of the item. The specified supplier then supplies the quantity of the item that corresponds to the purchase order.

On the other hand, if the inventory of one supplier is insufficient to meet the requested quantity, the server control unit 23 selects two or more suppliers from multiple suppliers that can supply the item as a supply supplier group. At this time, the server control unit 23 selects a supply supplier group so that the total inventory of the supply supplier group is sufficient to meet the requested quantity. The server control unit 23 then allocates the requested quantity of the item to the supply supplier group. For example, if the requested quantity is 50 units, the server control unit 23 allocates 24 units to supplier A and 26 units to supplier B.

In the example of Figure 2, the supply supplier group is made up of Supplier A and Supplier B. However, the supply supplier group may be made up of three or more suppliers. Furthermore, the server control unit 23 notifies the user that a purchase order is possible by notifying the user of the quantity to be purchased. The user confirms the quantity and performs an operation to place the purchase order. Next, the server control unit 23 accepts the purchase order and creates a sales order corresponding to the accepted purchase order. Furthermore, the server control unit 23 creates split sales orders as multiple sales orders linked with basic sales identification information (e.g., sales order number, etc.) that identifies the sales order. These multiple split sales orders are linked with split sales order identification information (e.g., sales order number and branch number, etc.) that identifies each of them.

In the example of FIG. 2, the server control unit 23 creates split sales order A and split sales order B as multiple sales orders. Split sales order A is a sales order to supplier A, and split sales order B is a sales order to supplier B. For example, if the requested quantity is 50 units, split sales order A includes 24 units as the number of items to be ordered from supplier A, and split sales order B includes 26 units as the number of items to be ordered from supplier B. The server control unit 23 then creates multiple purchase orders corresponding to the multiple split sales orders and sends them to the supplier terminal 60 of each supplier. In the example of FIG. 2, the server control unit 23 creates purchase order A and purchase order B as multiple purchase orders.

The supplier then supplies the goods according to the purchase order. For example, the supplier ships the goods specified by the model number in the quantity and at the shipping time specified in the purchase order to the destination specified in the purchase order. If the total inventory of multiple suppliers is insufficient to meet the requested quantity, the server control unit 23 may notify the user of this. The notification may also include a suggestion to change the desired delivery date or requested quantity.

[Control system]
Next, the schematic configuration of the control system of sales management system 100 will be described with reference to Figure 3. Procurement management server 20, which is an example of procurement management means, includes server control unit 23 as control means for procurement management server 20 and server memory 22 as a computer-readable non-transitory storage medium. Also, inventory management server 10, which is an example of inventory management means, includes inventory management control unit 13 as control means for inventory management server 10 and inventory management memory 12 as a computer-readable non-transitory storage medium.

The server control unit 23 and inventory management control unit 13 are configured as a computer that combines a processor that performs various arithmetic processing and operational control according to a predetermined program, internal memory required for the processor's operation, and other peripheral devices. The processor is, for example, a CPU (Central Processing Unit) or MPU (Micro-Processing Unit), and controls the entire server device and also comprehensively controls various processes based on programs stored in the server memory 22 or inventory management memory 12. The server control unit 23 and inventory management control unit 13 can also perform control according to programs stored on portable recording media such as CDs, DVDs, CF cards, and USB memory, or on external storage media such as cloud servers on the Internet.

The server memory 22 and inventory management memory 12 include RAM (Random Access Memory), which is the system work memory for the processor to operate, as well as storage devices such as ROM (Read Only Memory), HDD (Hard Disc Drive), and SSD (Solid State Drive) that store programs and system software. However, the server memory 22 is not limited to being provided as part of the procurement management server 20, but may also be provided as a database server that cooperates with the procurement management server 20. Similarly, the inventory management memory 12 is not limited to being provided as part of the inventory management server 10, but may also be provided as a database server that cooperates with the inventory management server 10. In the following description, the CPU performs various processing operations such as calculations, controls, and determinations in accordance with control programs stored in the ROM or HDD.

[Inventory management methods]
The inventory management memory 12, which serves as an example of a storage means for storing supply conditions, stores supply information 12A indicating the supply conditions of each supplier. As an example, the supply information 12A includes information specifying the items that the supplier can provide (e.g., the item model number) and the quantity of the items (e.g., the inventory amount). The inventory management memory 12 stores the quantity for each item in association with supplier identification information. The supply conditions may be sent directly by each supplier or may be input by an administrator of the inventory management server 10. The inventory management memory 12 also stores an inventory management program (not shown).

The inventory management control unit 13 acquires supply conditions based on the inventory management program, associates them with supplier identification information, and stores them in the inventory management memory 12. To this end, the inventory management control unit 13 is equipped with an update unit 13A as an example of an update means that acquires information from multiple suppliers and updates the supply conditions stored in the inventory management memory 12.

The update unit 13A is a logical device realized by a combination of computer hardware and software. The inventory management program stored in the inventory management memory 12 causes the inventory management control unit 13, which is a computer, to function as the update unit 13A. The update unit 13A may store a quantity less than the received inventory amount in the inventory management memory 12 as the supplier's inventory amount. This prevents delays in delivery of goods due to inventory shortages after a purchase order is received from a user. The update unit 13A may also store a quantity greater than the received inventory amount in the inventory management memory 12 as the supplier's inventory amount. For example, the update unit 13A may store in the inventory management memory 12 the quantity of goods obtained by adding the predicted increase in inventory amount predicted by the prediction unit 23E as the supplier's inventory amount.

As an example, the update unit 13A periodically or in real time receives and acquires the supply conditions sent by the supplier. Then, based on the acquired supply conditions, the update unit 13A updates the supply conditions stored in the inventory management memory 12 to the latest supply conditions. Alternatively, the update unit 13A may acquire information irregularly (for example, at any timing when the supplier sends the supply conditions) and update the supply conditions. Furthermore, the update unit 13A may acquire the latest supply conditions stored in any storage means and update the supply conditions stored in the inventory management memory 12. In this case, the update unit 13A may acquire information and update the supply conditions periodically (for example, at a specified time during the day). Furthermore, the update unit 13A may automatically acquire the supply conditions; for example, the update unit 13A may request the supplier terminal 60 to send the supply conditions.

The update unit 13A may also update the supply amount in a manner that matches the unit of the requested quantity input by the user. For example, suppose the requested quantity input by the user is number of items, and the supply amount sent by the supplier is expressed in units of dozens, each consisting of 12 items. In this case, the update unit 13A converts the unit of the supply amount to number of items and replaces it with the stored supply amount. Additionally, if the supply amount is expressed in units such as packs, each consisting of 6 items, pairs, size, or weight, the update unit 13A also converts the unit of the supply amount to the same unit as the requested quantity. Furthermore, if the user inputs the requested quantity in units such as dozens, each consisting of 12 items, the update unit 13A may convert the number of items in the supply amount to units such as dozen.

[Procurement management methods]
The server control unit 23 includes, as logical devices realized by a combination of computer hardware and software, an acquisition unit 23A, a selection unit 23B, an allocation unit 23C, an order unit 23D, a prediction unit 23E, an estimation unit 23F, a determination unit 23G, and a presentation unit 23H. The procurement management program PG stored in the server memory 22 causes the server control unit 23, which is a computer, to function as the acquisition unit 23A (an example of acquisition means), the selection unit 23B (an example of selection means), the allocation unit 23C (an example of allocation means), the order unit 23D (an example of order means), the prediction unit 23E (an example of prediction means), the estimation unit 23F (an example of estimation means), the determination unit 23G (an example of determination means), and the presentation unit 23H (an example of presentation means). In addition to the above logical devices, the server control unit 23 also includes logical devices (not shown) that control the switching of web page display in response to operations on the user terminal 40.

The server memory 22 stores a procurement management program PG that causes the server control unit 23 to execute various processes associated with selecting a group of supply suppliers and allocating the requested quantity of items. The procurement management program PG may function as a single program in cooperation with an inventory management program. The server memory 22 also stores request information 22A that indicates the required conditions for items requested by users. As an example, the request information 22A includes information that identifies the item requested by the user (e.g., the item's model number) and the required conditions for the item (e.g., the requested quantity and delivery date). In the request information 22A, the required conditions are linked to user identification information that identifies each user.

The user transmits the request conditions via the user terminal 40, and the acquisition unit 23A acquires the request conditions and stores them in the server memory 22. Alternatively, an administrator of the procurement management server 20 may store the request conditions acquired from the user in the server memory 22. In this case, the acquisition unit 23A acquires the request conditions from the server memory 22. Furthermore, the acquisition unit 23A may acquire the request conditions stored in any storage means and update the request conditions stored in the server memory 22.

The server memory 22 also stores order information 22B indicating the details of purchase orders from users. As an example, the order information 22B includes information identifying the item ordered by the user (e.g., the item's model number), information identifying the sales order corresponding to the purchase order (e.g., the sales order number), and the requested quantity of the item. The server memory 22 stores the requested quantity in association with each user's user identification information. The order information 22B also includes information indicating the details of the sales order and purchase order, and information indicating the allocation results by the allocation unit 23C. The server memory 22 also stores various data (not shown), such as user information, past quotation results, image data used to display web pages, and data including information such as the item's model number, name, or characteristics.

[Acquisition means]
The acquisition unit 23A acquires request conditions, including the requested quantity of the item requested by the user. As an example, the user inputs the requested quantity of the item they wish to purchase via a webpage provided by the server control unit 23. Specifically, the server control unit 23 authenticates the user through user authentication or the like. The server control unit 23 then displays the webpage on a display device (not shown) of the user terminal 40. On the webpage, the user performs an operation to specify the desired item, such as selecting a displayed image link or inputting an item model number or item name. As a result, the server control unit 23 displays an item screen 91 shown in FIG. 4 on the display device of the user terminal 40 of the authenticated user. Note that the screen configuration of the item screen 91 can be changed as appropriate; for example, the delivery date input field 91B and the quantity input field 91C may be combined into one.

The acquisition unit 23A also acquires supply conditions including the supply quantity of goods from each of multiple suppliers who can supply the goods. Specifically, the acquisition unit 23A acquires the supply conditions from the inventory management memory 12. Furthermore, if the supply conditions are updated, the acquisition unit 23A acquires the updated supply conditions from the inventory management memory 12. For example, the acquisition unit 23A requests the inventory management control unit 13 to search for the inventory quantity of the requested goods. The inventory management control unit 13 then searches for the inventory quantity of each supplier and transmits the inventory quantity as the search result to the acquisition unit 23A. Note that the supply conditions may be stored in the server memory 22 instead of the inventory management memory 12. In this case, the acquisition unit 23A reads and acquires the supply conditions from the server memory 22.

The item screen 91 shown in Figure 4 has an item field 91A, which displays the item name, item model number, and item image. In the example of Figure 4, "Shaft Holder" is displayed as the item name, and "ATHC3" is displayed as the item model number. In addition, an image of the shaft holder taken from an oblique angle is displayed as the item image. Note that the item image may also be a 3D model of the item.

The item screen 91 also has a delivery date input field 91B, which includes a user order number field for entering any symbol to identify the purchase order. Furthermore, the delivery date input field 91B also includes a delivery date field for the user to enter the delivery date of the item desired. When the user enters the delivery date in the delivery date field, the acquisition unit 23A acquires the delivery date entered by the user, includes it in the request information 22A, and stores it in the server memory 22. Note that Figure 4 shows an example in which a delivery date based on the shipping date of "2021/11/11" is entered, and "123456789" is entered as the user order number.

Furthermore, the item screen 91 has a quantity input field 91C, which has a quantity field 91D for entering the requested quantity of the item. When the user enters the requested quantity in the quantity field 91D, the acquisition unit 23A acquires the requested quantity entered by the user, includes it in the request information 22A, and stores it in the server memory 22. Furthermore, if the user wishes to purchase a quantity of items exceeding the purchasable quantity (51 or more in the example of FIG. 4), the user selects the delivery date confirmation button 91E to request confirmation of the delivery date from the server control unit 23. Upon receiving this request, the server control unit 23 notifies the user terminal 40 of the available shipping date for the quantity of items exceeding the purchasable quantity and the quantity of items that can be shipped by that available shipping date. Alternatively, upon receiving the request for confirmation of the delivery date, the server control unit 23 may inquire of the supplier about the available shipping date for the quantity of items exceeding the purchasable quantity and notify the user terminal 40 of the response.

Alternatively, the user may install application software on the user terminal 40 in advance and use this application software to input requirements such as the desired delivery date and requested quantity. Furthermore, the user may notify the administrator managing the procurement management server 20 of the requirements using other means, such as telephone or email. In this case, the administrator of the procurement management server 20 enters the requirements and stores them in the server memory 22. The user may also enter the requirements on a web page provided by another server. In this case, the acquisition unit 23A acquires the requirements from the other server. The requirements may also be included in a request for quotation, purchase order, inquiry, or the like.

The quantity input field 91C also displays the unit price per item, the total price, which is the price of the requested quantity of items, and the quantity available for purchase. In the example of Figure 4, "1,090 yen" is displayed as the unit price, "54,500 yen" as the total price, and "50 units" as the quantity available for purchase. Also, below the quantity available for purchase, "24 units" is displayed as the quantity that can be shipped on the day of the order. This quantity is the quantity that can be shipped on the day of the order out of the requested quantity of items that can be delivered by the desired delivery date entered by the user.

When allocating requested quantities to a group of supply suppliers as explained using the example of Figure 2, the supply timing of each supplier may differ. For example, Figure 4 shows that the group of supply suppliers can supply 50 units by the desired delivery date, of which 24 units can be supplied by suppliers who can supply immediately after the order. As an example, the quantity of goods that can be shipped on the day of the order is the quantity of goods that have already been transported by the supplier to the distributor and are stored at the distributor's logistics center.

Furthermore, the quantity input field 91C is provided with a details screen button 91F and an order button 91G. When the user performs an operation to select the details screen button 91F, the server control unit 23 causes the details screen 92 shown in FIG. 5 to be displayed on the display device of the user terminal 40. Furthermore, when the user performs an operation to select the order button 91G, the server control unit 23 causes the order confirmation screen 93 shown in FIG. 6 to be displayed on the display device of the user terminal 40.

[Presentation means]
The presentation unit 23H presents split shipping information to the user, indicating that the quantity of items allocated by the allocation unit 23C will be shipped separately. For example, the presentation unit 23H presents the quantity of items allocated by the allocation unit 23C and the shipping date, which represents the supply time of the items, to the user as split shipping information based on the allocation result by the allocation unit 23C. Specifically, the presentation unit 23H obtains information such as the allocated quantity and shipping date from the allocation unit 23C as the allocation result and presents it to the user as split shipping information. Specifically, on the details screen 92 shown in FIG. 5, the split shipping column 92C displays the quantity of items to be shipped separately and their shipping dates as split shipping information. Alternatively, the presentation unit 23H may present the split shipping information to the user by notifying them via other means, such as email. Note that the split shipping information may be a character string (e.g., "shipped separately") or a symbol indicating that the items will be shipped separately.

The split shipment column 92C also displays the order deadline. The order deadline is the deadline during which the shipping date based on the allocation result by the allocation unit 23C and the unit price and total amount as the estimate result by the estimation unit 23F are valid. If the user confirms the purchase order by the order deadline, the user can purchase the goods according to the displayed shipping date, unit price, and total amount. After the user confirms the purchase order, the ordering unit 23D then places an order for the quantity of goods allocated by the allocation unit 23C with each supplier in the supply supplier group. To do this, the ordering unit 23D accepts a purchase order from the user and, based on that purchase order, creates split sales orders in the same number as the number of suppliers included in the supply supplier group.

In the example of Figure 5, "2021/11/01" is displayed as the order deadline. Also displayed are the number of items to be shipped in the first shipment, "24 units," and the shipping date, "the day of the order." Furthermore, the number of items to be shipped in the second shipment, "26 units," and the shipping date, "2021/11/11," are displayed. Note that a condition for shipping on the day of the order may be set such as confirming the purchase order by a specified time (e.g., 12:00). Furthermore, the split shipment field 92C has an order button 92G. When the user selects the order button 92G, the server control unit 23 displays the order confirmation screen 93 shown in Figure 6 on the display device of the user terminal 40.

The details screen 92 also has an item field 91A and a required conditions field 92B. The item field 91A displays the item name, item model number, and item image. The required conditions field 92B displays the required conditions for the item entered by the user, such as the desired delivery date and requested quantity. The required conditions field 92B also displays the user order number, unit price, and total amount. The screen configuration of the details screen 92 can be changed as needed.

As shown in FIG. 6, the order confirmation screen 93 has an item field 91A, a required conditions field 92B, and an order field 93C. The item field 91A displays the item name, item model number, and item image. The required conditions field 92B displays the desired delivery date and requested quantity. The order field 93C displays the order deadline, the number of items to be shipped in installments, and the shipping date.

The order field 93C also includes a specification field 93D for specifying the shipping date. The user can input the desired shipping date in the specification field 93D for each of the first and second shipments. However, the shipping date the user can input must be a date after the available shipping date. For example, for the first shipment in Figure 6, the item can be shipped on the same day as the order, so the user can input a date after the day after the order. For the second shipment in Figure 6, the item can be shipped on November 11, 2021, so the user can input a date after November 11, 2021. The order field 93C also includes an order confirmation button 93E. When the user selects the order confirmation button 93E, the ordering unit 23D of the server control unit 23 accepts the purchase order and sends it to the supplier.

The presentation unit 23H also presents the user with bulk shipping information indicating that the requested quantity of items will be shipped in a bulk shipment. For example, the presentation unit 23H presents the user with the quantity of items to be shipped in a bulk shipment and the shipping date, which represents the supply time of the items, as bulk shipping information. Here, the quantity of items to be shipped in a bulk shipment matches the requested quantity. Specifically, a bulk shipping button 93F is provided in the order field 93C of the order confirmation screen 93. When the user selects the bulk shipping button 93F, the server control unit 23 displays the bulk shipping screen 94 shown in FIG. 7 on the display device of the user terminal 40. This bulk shipping screen 94 has a bulk shipping field 94C. The bulk shipping field 94C displays the number of items to be shipped in a bulk shipment and the shipping date as bulk shipping information. Alternatively, the presentation unit 23H may present the bulk shipping information to the user by notifying them by other means, such as email.

The bulk shipping field 94C also displays the order deadline, and if the user confirms the purchase order by the order deadline, the user can purchase the goods according to the displayed shipping date, unit price, and total amount. After the user confirms the purchase order, the ordering unit 23D then places orders with each supplier in the supply supplier group for the quantity of goods allocated by the allocation unit 23C. To do this, the ordering unit 23D accepts a purchase order from the user and, based on that purchase order, creates installment sales orders in the same number as the number of suppliers included in the supply supplier group.

Furthermore, the bulk shipping field 94C has a specification field 94D for specifying a shipping date. The user can input a desired shipping date in the specification field 94D for items to be shipped in a bulk shipment. However, the shipping date that the user can input must be a date that is later than the available shipping date. For example, if 24 of the 50 items to be shipped in a bulk shipment can be shipped at the time of the order and the remaining 26 items can be shipped on November 11, 2021, the user can input a date that is the day after November 11, 2021 or later. The bulk shipping field 94C also has an order confirmation button 94E. When the user selects the order confirmation button 94E, the ordering unit 23D accepts the purchase order and sends it to the supplier.

As an example of a bulk shipment of goods, multiple suppliers transport goods in the quantity based on the purchase orders they each received to a common collection point (e.g., a distributor's logistics base) specified by the purchase orders. For example, suppose the requested quantity is 50 units, purchase order A received by supplier A contains 24 units, and purchase order B received by supplier B contains 26 units. In this case, supplier A transports 24 units to the collection point, and supplier B transports 26 units to the same collection point. The company managing the collection point (e.g., a distributor) then transports the 50 units together to the destination specified by the user. The collection point may also be a logistics base of a transport company.

The bulk shipping screen 94 also has an item field 91A and a required conditions field 92B. The item field 91A displays the item name, item model number, and item image. The required conditions field 92B displays the required conditions for the item entered by the user, such as the desired delivery date and required quantity.

[Determination means and selection means]
The determination unit 23G determines whether an allocation condition for allocating a requested quantity of an item to two or more suppliers among a plurality of suppliers is satisfied based on the request conditions and supply conditions acquired by the acquisition unit 23A. As an example, the determination unit 23G determines whether the allocation condition is satisfied when the user inputs a requested quantity of the request conditions. Alternatively, the determination unit 23G may determine whether the allocation condition is satisfied when the user inputs a requested quantity that exceeds a reference quantity preset for each item. Then, when the allocation condition is satisfied, the selection unit 23B selects two or more suppliers from the plurality of suppliers as a supply supplier group. Specifically, when the allocation condition is satisfied, the selection unit 23B selects a specific supplier and at least one other supplier different from the specific supplier from the plurality of suppliers as a supply supplier group.

As an example, the selection unit 23B selects one specific supplier from among multiple suppliers. The determination unit 23G then determines that the allocation conditions are met if the requested quantity is greater than the supply volume of the specific supplier. For example, specific suppliers are set in advance for each item, and the selection unit 23B selects the specific supplier set for the item included in the requested conditions. If the determination unit 23G then determines that the allocation conditions are met, the selection unit 23B further selects at least one other supplier different from the specific supplier. For example, the selection unit 23B selects, from among the multiple suppliers, two or more suppliers who can supply the item by the delivery date of the requested conditions as a supply supplier group based on the supply time of the supply conditions. In this way, the selection unit 23B selects a supply supplier group consisting of the specific supplier and other suppliers. As a result, the requested quantity of the item that exceeds the supply volume of the specific supplier can be allocated to other suppliers.

The selection unit 23B also references the delivery date in the requested conditions and the supply time in the supply conditions to search for suppliers who can supply (e.g., ship) the goods by the delivery date. For example, if the delivery date is November 3rd and the requested quantity is 50 units, Supplier A's shipping date is November 2nd and the supply amount is 24 units, Supplier B's shipping date is November 3rd and the supply amount is 26 units, and Supplier C's shipping date is November 4th and the supply amount is 50 units. In this case, since Supplier C's shipping date is after the delivery date, the selection unit 23B selects Supplier A and Supplier B as the supply supplier group. Note that if the selection unit 23B cannot find a supplier who can supply the goods by the delivery date, the server control unit 23 notifies the user terminal 40 of the available shipping date of the goods and the quantity of goods that can be shipped by that available shipping date, just as when the user orders a quantity that exceeds the available purchase quantity. The user confirms and modifies the delivery date and performs the purchase order operation described above.

For example, the selection unit 23B searches for a supplier that can supply the largest amount of goods by the delivery date of the required conditions, and selects this as the other supplier. The selection unit 23B may also search for a supplier that can supply goods by the delivery date of the required conditions in the shortest time, based on the supply time of the supply conditions, and select this as the other supplier. Alternatively, the selection unit 23B may select a supplier that can supply the largest amount of goods, as indicated by the prediction result of the prediction unit 23E (described below), as the other supplier. The selection unit 23B may also select a supplier that can supply goods in the shortest time, as indicated by the prediction result of the prediction unit 23E, as the other supplier.

The selection unit 23B may also select, based on the supply time, a supplier from among multiple suppliers that can supply the goods by the delivery date and has the largest supply volume as the specified supplier. In this case, the selection unit 23B refers to the supply conditions to search for the supplier that can supply the largest amount of goods and selects this supplier as the specified supplier. For example, the selection unit 23B selects a supplier with a large inventory volume as the specified supplier so that suppliers with a large supply volume are given priority in supplying goods. Furthermore, the selection unit 23B selects, as another supplier, the supplier with the second largest supply volume after the specified supplier.

Furthermore, the selection unit 23B may select as the specific supplier a supplier from among multiple suppliers that can supply the goods by the delivery date and has the fastest or shortest supply time based on the supply time. In this case, the selection unit 23B references the supply conditions to search for the supplier with the fastest or shortest supply time and selects it as the specific supplier. Furthermore, the selection unit 23B selects as another supplier a supplier with the next fastest or shortest supply time after the specific supplier. As a result, suppliers that can supply goods to the user more quickly are included in the supply supplier group. The selection unit 23B may select the supply supplier group based on costs such as unit prices or transportation costs in the supply conditions. Note that the costs may include other costs such as raw material costs, processing costs, production costs, taxes such as customs duties, storage costs, export costs, and import costs.

As another example, the determination unit 23G determines that the allocation conditions are met when the requested quantity is greater than the predicted supply quantity obtained by subtracting the predicted purchase quantity predicted by the prediction unit 23E from the supply quantity of a specific supplier. For example, a purchase order from a specific supplier by another user may be predicted close to the desired delivery date. In this case, the predicted purchase quantity by the other user is subtracted to prevent the inventory quantity of the specific supplier from reaching zero. If the inventory quantity of a specific supplier reaches zero, delays will occur in the delivery of purchase orders from other users, but subtracting the predicted purchase quantity can prevent such delays. Alternatively, the determination unit 23G may determine that the allocation conditions are met when the requested quantity is greater than a reference quantity preset for each item.

As yet another example, the determination unit 23G determines that the allocation conditions are met when the requested quantity is greater than the predicted supply quantity obtained by adding the predicted increase amount as a prediction result predicted by the prediction unit 23E (described below) to the supply quantity of a specific supplier. For example, an increase in supply quantity may be predicted before the supply conditions are updated. In this case, even if the supply quantity of a specific supplier at the time of selection is less than the requested quantity, the determination unit 23G adds the predicted increase amount in anticipation of an increase in the inventory quantity of the specific supplier. In this way, by taking the predicted increase amount into account, the requested quantity that exceeds the predicted supply quantity of the specific supplier can be allocated to other suppliers.

[Distribution means]
The allocation unit 23C allocates the requested quantity of the request conditions to the supply supplier group selected by the selection unit 23B. As an example, the allocation unit 23C allocates an amount of the requested quantity corresponding to the supply amount of the specific supplier to the specific supplier. Then, the allocation unit 23C allocates the remaining amount of the requested quantity to other suppliers in the supply supplier group. For example, if the requested quantity is 50 units and the supply amount of specific supplier A is 24 units, the allocation unit 23C allocates the remaining 26 units to another supplier B. This allows the selected supply supplier group to supply the product to the user even if the requested quantity of the product is greater than the supply amount of the specific supplier. Furthermore, when a user places an order for a large quantity of product through e-commerce, the requested quantity can be dynamically allocated to each of the multiple suppliers constituting the supply supplier group. This reduces supplier inventory and enables the product to be shipped in a short period of time.

As another example, the allocation unit 23C may allocate the requested quantity to each supplier selected in the supply supplier group in equal numbers. For example, if the requested quantity is 50 units, the allocation unit 23C may allocate 25 units to specific supplier A and 25 units to other supplier B. The allocation unit 23C may also allocate the largest requested quantity to a specific supplier. For example, if the requested quantity is 50 units, the allocation unit 23C may allocate 26 units to specific supplier A and 24 units to other supplier B.

Furthermore, in order to average out inventory amounts, the allocation unit 23C may allocate requested quantities so that the variance of inventory amounts becomes smaller. For example, suppose that specific supplier A has 30 units in stock, other supplier B has 20 units in stock, other supplier C has 15 units in stock, and the requested quantity is 50 units. In this case, the allocation unit 23C allocates 25 units to specific supplier A, 15 units to other supplier B, and 10 units to other supplier C. As a result, the inventory amounts of specific supplier A, other supplier B, and other supplier C will each be 5 units, and no variance will occur in inventory amounts.

Furthermore, the allocation unit 23C may allocate the requested quantity based on multiple conditions. As an example, the allocation unit 23C allocates any quantity that exceeds the supply amount that a specific supplier can provide to other suppliers in equal numbers. For example, if the requested quantity is 50 units and specific supplier A's supply amount is 24 units, the allocation unit 23C will allocate 13 of the remaining 26 units to other supplier B, and the remaining 13 units to other supplier C.

[Ordering method]
The ordering unit 23D places an order for the quantity of goods allocated by the allocation unit 23C with the supply supplier group. For example, the user confirms the details of the quotation and confirms the purchase order (selects the order confirmation button 93E in FIG. 6). Then, upon receiving the confirmation of the purchase order, the ordering unit 23D places an order for the goods with the suppliers included in the supply supplier group. To this end, the presentation unit 23H presents to the user the quantity of goods allocated by the allocation unit 23C and the shipping date as the supply time of the goods. As an example, the presentation unit 23H presents the split shipment information to the user by displaying the shipping date and quantity of goods on the details screen 92 in FIG. 5.

In the example of Figure 2, the ordering unit 23D, which has received a confirmed purchase order, creates split sales orders in the same number as the number of suppliers included in the supply supplier group, based on the purchase order from the user. Specifically, the ordering unit 23D creates split sales orders A and B corresponding to suppliers A and B. The ordering unit 23D also includes information identifying the items and information indicating the quantity of allocated items in the split sales orders. This information is linked to the split sales order identification information, and is stored by the server memory 22 as part of the order information 22B.

The ordering unit 23D then sends purchase orders corresponding to the installment sales orders to each supplier to place orders for the goods. In the example of Figure 2, the ordering unit 23D sends purchase order A corresponding to installment sales order A to supplier A, and purchase order B corresponding to installment sales order B to supplier B. The ordering unit 23D also includes in the purchase order information identifying the goods, information indicating the quantity of goods to be supplied, the delivery date of the goods, and information indicating the destination of the goods. This information is linked to purchase order identification information that identifies the purchase order, and is stored by the server memory 22 as part of order information 22B.

The supplier who receives the purchase order then ships the goods on or before the delivery date and transports them to the user. As an example of shipping goods, multiple suppliers transport the quantity of goods based on the purchase orders they each received to the destination specified by the user. For example, suppose the requested quantity is 50 units, purchase order A received by supplier A contains 24 units, and purchase order B received by supplier B contains 26 units. In this case, supplier A transports 24 units of goods to the destination, and supplier B transports 26 units of goods to the destination. In this way, because the ordering unit 23D creates the split sales order, the user does not have to place purchase orders with multiple suppliers. Note that the ordering unit 23D may create the split sales order at the same time that the estimating unit 23F creates the estimate result.

Furthermore, when an obstructing condition that obstructs the supply of goods occurs for at least one supplier in the supply supplier group, the ordering unit 23D may order the quantity of goods allocated to the supplier for which the obstructing condition occurred from a supplier among the multiple suppliers who can supply the goods. For example, a supplier may experience an unexpected delivery delay between the time the purchase order is sent and the shipping date. In this case, the selection unit 23B refers to the supply conditions stored in the inventory management memory 12 and searches for a supplier among the multiple suppliers who can supply the goods by the delivery date. Alternatively, the selection unit 23B searches for a supplier among the multiple suppliers who can supply the goods earliest. The ordering unit 23D then sends a purchase order to that supplier and orders the quantity of goods allocated to the supplier for which the obstructing condition occurred.

As an example, the selection unit 23B determines that an obstruction condition has occurred when a notification of a delivery delay or inability to deliver is received from a supplier. Alternatively, the selection unit 23B determines that an obstruction condition has occurred when the goods are not supplied by the delivery date, for example, when a shipment notification of the goods is not received from the supplier by the delivery date. The selection unit 23B may also determine that an obstruction condition has occurred when it detects the occurrence of a natural disaster, disaster, transportation disruption, or the like.

[Prediction means]
The prediction unit 23E predicts demand for goods for a predetermined period. In this case, the selection unit 23B selects a group of supply suppliers based on the prediction result by the prediction unit 23E so as to minimize the variation in inventory levels among multiple suppliers over the predetermined period. As an example, the prediction unit 23E predicts the purchase volume of goods for a predetermined period (e.g., one week) and outputs the predicted purchase volume as the prediction result to the selection unit 23B. The selection unit 23B selects a group of supply suppliers based on the predicted purchase volume and the inventory volume acquired by the acquisition unit 23A so as to minimize the variation in inventory levels. This makes it possible to select suppliers so as to minimize the variation in inventory levels over the predetermined period for which demand is predicted, and average out the inventory levels of the suppliers.

For example, suppose that specific supplier A has 30 units in stock, other supplier B has 20 units in stock, the requested quantity is 25 units, and the forecast purchase quantity for one week is 30 units. In this case, specific supplier A's inventory is greater than the requested quantity, but if only specific supplier A is selected, the difference in inventory between specific supplier A and other supplier B over the course of one week will be 15 units, resulting in variation. Therefore, the selection unit 23B selects specific supplier A and other supplier B as a supply supplier group so that it can also be allocated to other supplier B. In this case, the allocation unit 23C may allocate 17 units to specific supplier A and 8 units to other supplier B to reduce variation in inventory quantities among multiple suppliers over a specified period.

As an example, the prediction unit 23E predicts the demand for goods, such as a predicted increase in supply, a predicted supply volume, a predicted supply time, and a predicted purchase volume. For example, the prediction unit 23E predicts the current demand for goods for the same period based on past supply volumes or purchase quantities. Specifically, the prediction unit 23E outputs a prediction result in which the past supply volume or purchase volume is the current supply volume or purchase volume for the same period. Alternatively, the prediction unit 23E may predict the demand for goods using a learning model constructed based on learning data including actual data such as past supply volumes or purchase volumes. Note that the learning model may be constructed by the inventory management server 10 or the procurement management server 20, or may be a pre-constructed learning model.

[Estimation Method]
The estimating unit 23F notifies the user of the unit price of the item and the total price of the requested quantity of items as the estimate result. Specifically, the estimating unit 23F notifies the user by displaying the unit price and the total price on the details screen 92 shown in FIG. 5. For example, the estimating unit 23F creates the estimate result by referring to the supply conditions (e.g., unit price of the item) acquired by the acquiring unit 23A. The estimate result may also include the shipping date, the number of working days required for shipping, etc.

[Device]
The user terminal 40 includes a user terminal control unit 45 that controls the user terminal 40 and a user terminal memory 44 that stores a control program. The user terminal control unit 45 is a computer that combines a processor that executes various arithmetic processes and operational control according to a predetermined program with other peripheral devices. The user terminal 40 also includes a display device and an input device (not shown). The input device (not shown) may be a keyboard, numeric keypad, touch panel, or the like, and the user uses the input device to input the requested quantity, etc. The display device (not shown) displays web pages such as various screens, and the user places a purchase order for the item according to the displayed web pages.

The supplier terminal 60 also includes a supplier terminal control unit 65 that controls the supplier terminal 60, and a supplier terminal memory 64 that stores a control program. The supplier terminal control unit 65 is a computer that combines a processor that performs various calculation processes and operational control according to a predetermined program with other peripheral devices. The supplier terminal 60 also includes a display device and input device (not shown). The supplier uses the input device to input supply amounts, etc.

As an example, the processors of the user terminal control unit 45 and the supplier terminal control unit 65 are, for example, a CPU or MPU, which control the entire terminal and centrally control various processes based on control programs stored in the user terminal memory 44 and the supplier terminal memory 64. The user terminal memory 44 and the supplier terminal memory 64 also include RAM, which serves as system work memory for the processor's operation, as well as storage devices such as ROM, HDD, and SSD, which store programs and system software. The user terminal control unit 45 and the supplier terminal control unit 65 can also perform control according to programs stored on portable storage media such as CDs, DVDs, CF cards, and USB memory, or on external storage media such as cloud servers on the Internet. The user terminal memory 44 and the supplier terminal memory 64 are external storage devices that include non-volatile storage media (computer-readable, non-temporary storage media) such as hard disks and semiconductor storage devices.

[Sort processing]
The allocation process in the procurement management system will be described with reference to FIG. 8. When a supplier transmits supply conditions, including a supply quantity, to the inventory management server 10, the update unit 13A acquires the supply conditions (S101). Then, the update unit 13A updates the supply conditions stored in the inventory management memory 12 to the latest supply conditions based on the acquired supply conditions (S102). Alternatively, if the supply conditions are the first to be transmitted, the update unit 13A stores the acquired supply conditions in the inventory management memory 12. Furthermore, a user inputs requested conditions, including a requested quantity of an item desired to be purchased, via a web page provided by the server control unit 23. Then, the acquisition unit 23A acquires the requested conditions entered by the user (S103). Furthermore, the acquisition unit 23A acquires the supply quantity from the inventory management server 10.

The determination unit 23G compares the requested quantity and the supply quantity acquired by the acquisition unit 23A (S104) and determines whether the allocation conditions are met (S105). At this time, if the requested quantity is less than the supply quantity of the specified supplier, the determination unit 23G determines that the allocation conditions are not met (NO in S105). In other words, the determination unit 23G determines that the specified supplier can supply the goods alone. In this case, the requested quantity is not allocated, so the estimation unit 23F notifies the user that the same amount as the requested quantity is the available purchase quantity (S106). For example, the estimation unit 23F displays the quantity and shipping date of the goods on the display device of the user terminal 40. The user then confirms the quantity and performs an operation to confirm the purchase order, and the ordering unit 23D accepts the purchase order (S107). Next, the ordering unit 23D sends a purchase order to the specified supplier to order the goods (S108).

On the other hand, if the requested quantity is greater than the supply quantity of the specified supplier, the determination unit 23G determines that the allocation conditions are met (YES in S105). Then, the selection unit 23B selects the specified supplier and other suppliers who can supply the goods by the delivery date of the requested conditions as a supply supplier group (S109). The allocation unit 23C allocates the requested quantity of the requested conditions to the supply supplier group selected by the selection unit 23B (S110). Next, the estimation unit 23F notifies the user of the allocated quantity (S106). For example, the estimation unit 23F displays the allocated quantity and the shipping date of the goods on the display device of the user terminal 40. The user then confirms the quantity and performs an operation to confirm the purchase order, and the ordering unit 23D accepts the purchase order (S107). Next, the ordering unit 23D sends a purchase order to each supplier in the supply supplier group to order the goods (S108). This completes the allocation process.

As described above, the procurement management system according to the first embodiment can shorten the time from purchase order to delivery of goods by allocating the quantity of goods requested by a user to multiple sub-suppliers. In other words, by ordering a quantity of the requested quantity that exceeds the supply quantity from other suppliers, goods can be delivered more quickly. Furthermore, when ordering a large quantity of goods, a user does not need to calculate the quantity to be purchased from each of multiple suppliers. Nor does the user need to place purchase orders with each of multiple suppliers. This eliminates the need for calculations and operations when placing a purchase order, thereby shortening the time required for the purchase order. Furthermore, because the supply quantity of each supplier is dynamically updated, the need to allocate the requested quantity can be determined based on the most recent supply quantity.

The control method for the procurement management system described above is executed by the inventory management control unit 13 and the server control unit 23, which function as computers, working together. Specifically, the control method includes an acquisition process, a determination process, a selection process, and an allocation process. The acquisition process acquires request conditions, including the requested quantity of an item requested by a user, and supply conditions, including the supply amounts of the item from each of multiple suppliers that can supply the item. The determination process determines, based on the request conditions and supply conditions, whether allocation conditions for allocating the requested quantity of the item to two or more of the multiple suppliers are met. If the allocation conditions are met, the selection process selects two or more suppliers from the multiple suppliers as a supply supplier group. The allocation process then allocates the requested quantity to the supply supplier group. Alternatively, one of the inventory management control unit 13 and the server control unit 23 may execute the acquisition process, determination process, selection process, and allocation process.

Second Embodiment
The second embodiment will be described with reference to Figures 9 and 10. The procurement management system provided in the sales management system 200 of the second embodiment differs from the first embodiment in that it creates multiple purchase orders without creating multiple sales orders. In the description of the second embodiment, differences from the first embodiment will be described, and components already described will be given the same reference numbers and their description will be omitted. Unless otherwise specified, components with the same reference numbers perform substantially the same operations and functions, and their effects are also substantially the same.

With reference to Figure 9, procurement management using the procurement management system of the second embodiment will be described. The supplier terminals 60 include a terminal for supplier A and a terminal for supplier B. Each supplier terminal 60 transmits supply conditions, including inventory quantities, to the inventory management server 10 at any time. The inventory management control unit 13 of the inventory management server 10 then associates the received supply conditions with the respective supplier identification information for each item and stores them in the inventory management memory 12.

A user wishing to purchase an item accesses a website provided by the procurement management server 20 from the user terminal 40. Specifically, the server control unit 23 of the procurement management server 20 displays an item screen 95, as shown in FIG. 10, on the display device of the user terminal 40. The item screen 95 includes an item field 91A and a delivery date input field 91B. The item screen 95 also includes a quantity input field 95C, which includes a quantity field 95D for entering the requested quantity of the item. When the user enters the requested quantity in the quantity field 95D, the server control unit 23 acquires the requested quantity entered by the user and stores it in the server memory 22 as part of request information 22A. Furthermore, if the user wishes to purchase an item in a quantity that exceeds the available purchase quantity, the user selects the delivery date confirmation button 95E to request confirmation of the delivery date.

The user enters the requested quantity and delivery date of the item via the item screen 95. The server control unit 23 of the procurement management server 20 acquires the input request conditions and stores them in the server memory 22 of the procurement management server 20. The server control unit 23 then acquires the inventory amount from the inventory management server 10 and selects a specific supplier that can supply the requested item. If the specific supplier's inventory amount is sufficient for the requested quantity, the server control unit 23 selects that specific supplier. The server control unit 23 then notifies the user that a purchase order is possible, and the user performs an operation to submit the purchase order. For this purpose, the item screen 95 shown in FIG. 10 has an order button 95G. When the user selects the order button 95G, the server control unit 23 displays an order confirmation screen (not shown) on the display device of the user terminal 40. The user then confirms the contents of the purchase order on the order confirmation screen and selects the order confirmation button to place the purchase order. Note that the item screen 95 supports bulk delivery, so the details screen button 91F is not provided.

On the other hand, if the inventory of a specific supplier is insufficient to meet the requested quantity, the server control unit 23 selects the specific supplier and other suppliers from multiple suppliers that can supply the item as a supply supplier group. At this time, the server control unit 23 selects a supply supplier group so that the total inventory of the supply supplier group is sufficient to meet the requested quantity. The server control unit 23 then allocates the requested quantity of the item to the supply supplier group.

Furthermore, the server control unit 23 notifies the user that a purchase order is possible by presenting the user with the quantity of items available for purchase as bulk shipping information. Furthermore, when the user selects the order button 95G (Figure 10), the server control unit 23 causes an order confirmation screen (not shown) to be displayed on the display device of the user terminal 40. The user then confirms the contents of the purchase order on the order confirmation screen and selects the order confirmation button to place the purchase order. The server control unit 23 then accepts the purchase order and creates multiple purchase orders linked with basic sales identification information that identifies the sales orders corresponding to the accepted purchase orders. Each of these multiple purchase orders is linked to a basic sales identification information that identifies it.

In the example of Figure 9, the server control unit 23 creates purchase order A and purchase order B corresponding to one sales order as multiple purchase orders. Purchase order A is an order to supplier A, and purchase order B is an order to supplier B. The server control unit 23 then sends the multiple purchase orders to the supplier terminals 60 of the respective suppliers. Each supplier then supplies the items according to the purchase orders. For example, a supplier ships items specified by model numbers in the quantity and for the shipping period specified in the purchase orders to a common collection point specified by the purchase orders. In this case, supplier A and supplier B transport the quantities of items allocated to them to the collection point. The business entity (e.g., a retailer) managing the collection point then collectively transports the collected items to the destination specified by the user.

[Presenting Sales Order Information]
Next, we will explain how sales order information indicating the contents of a sales order corresponding to a purchase order is presented to a user when the allocation conditions are met. As shown in Figure 3, the server control unit 23 includes an acquisition unit 23A, a selection unit 23B, an allocation unit 23C, an ordering unit 23D, a determination unit 23G, and a presentation unit 23H. The acquisition unit 23A acquires request conditions including the requested quantity and delivery date of an item requested by the user, and supply conditions including the supply amounts of the item from each of multiple suppliers that can supply the item. Furthermore, the determination unit 23G determines whether the allocation conditions for allocating the requested quantity of the item to two or more of the multiple suppliers are met based on the request conditions and supply conditions.

For example, the selection unit 23B selects one specific supplier from among the multiple suppliers. Then, the determination unit 23G determines that the allocation conditions are met if the requested quantity is greater than the supply quantity of the specific supplier. Furthermore, if the allocation conditions are met, the selection unit 23B selects two or more suppliers from the multiple suppliers as a supply supplier group. For example, the selection unit 23B selects the specific supplier and at least one other supplier different from the specific supplier from among the multiple suppliers as a supply supplier group. Then, the allocation unit 23C allocates the requested quantity of the item to the supply supplier group.

The ordering unit 23D also functions as a creation unit, which is an example of a creation means, that accepts a purchase order for an item from a user and creates a single sales order corresponding to the accepted purchase order. When a supply supplier group is selected (i.e., when the allocation conditions are met), the creation unit creates multiple purchase orders corresponding to the single sales order so that they are linked to the basic sales identification information that identifies the sales order.

The presentation unit 23H also presents the user with sales order information corresponding to the order for the goods. Specifically, the presentation unit 23H presents the user with sales order information indicating the contents of one sales order corresponding to the purchase order. Here, the sales order information is information that specifies the contents of the sales order. The ordering unit 23D then places an order for the goods with the selected group of supply suppliers. Specifically, the ordering unit 23D accepts the user's selection of bulk shipment and places an order for the quantity of goods allocated by the allocation unit 23C with each supplier in the group of supply suppliers.

As described above, the ordering unit 23D, which functions as a creation unit, creates one sales order corresponding to a purchase order, and one or more purchase orders corresponding to one sales order. Therefore, even if the allocation conditions are met and a supply supplier group is selected, multiple split sales orders are not created. Then, the presentation unit 23H presents sales order information indicating the contents of one sales order to the user, even when a supply supplier group is selected.

As a result, users can inspect delivered goods as long as they have the information for one sales order. On the other hand, when multiple split sales orders are created, a split sales order number is generated for each split sales order. For example, if each split sales order has a split sales order number, the same number of invoices as the number of split sales orders are issued. As a result, users must perform inspection work the same number of times as the number of split sales orders. In contrast, when only one sales order is created, only one invoice is issued. The sales order information presented to the user also corresponds to one sales order. As a result, inspection work only needs to be done once, reducing the management burden on the user.

The procurement management system according to the second embodiment can shorten the time from purchase order to delivery of goods by allocating the quantity of goods requested by a user to multiple sub-suppliers. Furthermore, when ordering a large quantity of goods, the user does not need to calculate the quantity to be purchased from each of multiple suppliers. The user also does not need to place purchase orders with each of multiple suppliers. This eliminates the need for calculations and operations when placing a purchase order, thereby reducing the time required for the purchase order. Furthermore, because the supply volume of each supplier is dynamically updated, the need to allocate the requested quantity can be determined based on the most recent supply volume.

The present invention has been described above with reference to various embodiments, but the present invention is not limited to these embodiments. The present invention also includes inventions that have been modified without departing from the scope of the present invention, as well as inventions that are equivalent to the present invention. Furthermore, the various embodiments and variations can be combined as appropriate without departing from the scope of the present invention.

For example, the inventory management server 10 and the procurement management server 20 may be a single server. Furthermore, each logical device provided on the inventory management server 10 may be provided on the procurement management server 20. Furthermore, each logical device provided on the procurement management server 20 may be provided on the inventory management server 10. Furthermore, each logical device provided on the inventory management server 10 and the procurement management server 20 may be provided on a separate server. In this case, the separate server, the inventory management server 10, and the procurement management server 20 work together to form a procurement management system.

[First Modification]
In the description of the first modified embodiment, differences from the first and second embodiments will be described, and the same reference numerals will be used for the components that have already been described, and their description will be omitted. Unless otherwise specified, the components that have the same reference numerals perform substantially the same operations and functions, and the effects thereof will also be substantially the same.

The acquisition unit 23A (Figure 3) acquires request conditions, including the requested quantity and delivery date of the item requested by the user, and supply conditions, including the supply amount of the item from each of multiple suppliers who can supply the item. Furthermore, the determination unit 23G determines whether or not allocation conditions, which require the requested quantity of the item to be allocated to two or more of the multiple suppliers, are met based on the request conditions and supply conditions. If the allocation conditions are not met, the selection unit 23B selects one of the multiple suppliers. Furthermore, if the allocation conditions are met, the selection unit 23B selects two or more suppliers from the multiple suppliers as a supply supplier group.

The ordering unit 23D functions as a creation unit, which is an example of a creation means, that accepts purchase orders for items from users and creates sales orders corresponding to the accepted purchase orders. When a supply supplier group is selected, the creation unit creates multiple installment sales orders (Figure 2) for each supplier in the supply supplier group, linked to the basic sales identification information that identifies the sales order. Furthermore, the creation unit creates purchase orders for suppliers corresponding to each installment sales order.

Then, the ordering unit 23D places an order for the goods with one supplier selected by the selection unit 23B, or with a group of supply suppliers selected by the selection unit 23B. Specifically, the ordering unit 23D sends a purchase order to each supplier to place an order for the goods. The presentation unit 23H also presents sales order information corresponding to the order for the goods to the user. This sales order information identifies the contents of each of the multiple split sales orders. For example, the sales order information includes the delivery date of the goods (for example, the shipping date), the quantity of the goods, and identification information that identifies the purchase order (for example, split sales order identification information consisting of a sales order number and a branch number).

The selection unit 23B determines whether an obstructing condition has occurred that prevents the supply of goods by the due date for a selected supplier or a faulty supplier, which is at least one supplier in the selected group of suppliers. This obstructing supplier is a supplier that is no longer able to supply goods by the due date. As an example, the selection unit 23B determines that an obstructing condition has occurred when a delay notice is received from the faulty supplier or when the shipping date for the goods has passed.

If an obstructing condition occurs, the selection unit 23B selects at least one alternative supplier from among the multiple suppliers that can supply the quantity of goods that was ordered from the failed supplier. This alternative supplier is a supplier that can supply the quantity of goods included in the required conditions by the due date of the goods included in the required conditions. The alternative supplier may be one supplier or multiple suppliers. Alternatively, the selection unit 23B may determine that an obstructing condition has occurred when the administrator of the procurement management server 20 inputs that an obstructing condition has occurred.

The ordering unit 23D then cancels the order placed with the failed supplier and places an order for the quantity of goods that had been ordered from the failed supplier with an alternative supplier. The presentation unit 23H also functions as a change condition determination unit that determines whether the change conditions for the sales order information are met. If the change conditions for the sales order information are not met, the presentation unit 23H maintains the presentation of the sales order information as is. For example, when the user opens the details screen 92 (Figure 5), the presentation unit 23H maintains the presentation of the sales order information as is by not changing the sales order information displayed on the details screen 92. Alternatively, the presentation unit 23H may maintain the presentation as is by notifying the user of the sales order information that does not include changes in response to a user request.

On the other hand, the presentation unit 23H presents the change to the sales order information to the user when the change conditions for the sales order information are met. For example, when there is no alternative supplier that can supply the goods by the delivery date, the presentation unit 23H determines that the change conditions for the sales order information are met and presents the change to the sales order information to the user. Alternatively, the presentation unit 23H may determine that the change conditions are met when the administrator of the procurement management server 20 inputs that the change conditions are met.

Specifically, when presenting changes to sales order information, the presentation unit 23H presents the contents of the changed installment sales order or sales order (e.g., delivery date and quantity of items, etc.) to the user. Also, if the delivery date (e.g., shipping date) changes, the presentation unit 23H presents the new delivery date to the user. Furthermore, the presentation unit 23H may present changes to the sales order information to the user by highlighting the changes. Furthermore, the presentation unit 23H may present to the user whether the order needs to be canceled and the contents of the installment sales order or sales order before the change.

As an example, the creation unit creates a new installment sales order when the conditions for changing the sales order information are met. The presentation unit 23H then presents the contents of the new installment sales order to the user, thereby presenting the changes to the sales order information to the user. Specifically, the presentation unit 23H notifies the user of the contents of the new installment sales order (e.g., delivery date of the items, quantity of the items, installment sales order identification information, etc.) by email or the like. Alternatively, the presentation unit 23H may present the contents of the new installment sales order to be displayed on the details screen 92 (Figure 5) when the user opens the details screen 92.

In addition, if the number of suppliers supplying goods to the user increases or decreases, the presentation unit 23H determines that the conditions for changing the sales order information have been met and presents the changes to the sales order information to the user. For example, if there are two alternative suppliers for one failed supplier, the number of suppliers supplying goods increases, so the changes to the sales order information are presented to the user. The creation unit then creates two new split sales orders in place of one split sales order, so the number of split sales orders also increases. In addition, if there is one alternative supplier for two failed suppliers, the number of suppliers supplying goods decreases, so the changes to the sales order information are presented to the user. The creation unit then creates one new split sales order in place of two split sales orders, so the number of split sales orders also decreases.

In addition, if the quantity of goods supplied by each alternative supplier increases or decreases relative to the quantity ordered from the affected supplier (i.e., the allocated quantity), the presentation unit 23H determines that the conditions for changing the sales order information have been met and presents the changes to the sales order information to the user. For example, if the quantity ordered from one affected supplier is allocated to two alternative suppliers, the quantity of goods supplied by each alternative supplier will decrease relative to the quantity ordered from the affected supplier, and the changes to the sales order information will be presented to the user. In addition, if the quantity ordered from two affected suppliers is allocated to one alternative supplier, the quantity of goods supplied by the alternative supplier will increase relative to the quantity ordered from the affected supplier, and the changes to the sales order information will be presented to the user. In these cases, the creation unit creates a new split sales order based on the increased or decreased quantities.

If the change conditions are met, the creation unit creates a new installment sales order. The user then discards the details specified by the previously submitted installment sales order (e.g., installment sales order identification information) and inspects the delivered items based on the details specified by the new installment sales order. Therefore, the presentation unit 23H must present the details of the new installment sales order to the user. On the other hand, if the delivery date of the items will not be changed because the items can be supplied by the delivery date, and the number of suppliers and the quantity of items will not increase or decrease, the change conditions are not met. Therefore, the creation unit does not need to create a new installment sales order. In this case, even if an obstruction condition occurs, the presentation unit 23H does not present changes to the sales order information to the user. Therefore, the user does not need to discard the installment sales order identification information, and an increase in the burden can be suppressed even when placing an order with an alternative supplier.

[Presentation process]
Referring to FIG. 11 , a presentation process for presenting changes to sales order information to a user when an obstructing condition occurs that prevents the supply of goods by the delivery date will be described. FIG. 11 shows a flowchart of the presentation process for creating multiple installment sales orders. First, the ordering unit 23D accepts the purchase order when the user confirms the purchase order. Then, the presentation unit 23H presents the sales order information to the user (S201). For example, if one supplier is selected (i.e., the allocation condition is not satisfied), the presentation unit 23H presents the user with sales order information (e.g., sales order number, etc.) indicating the contents of one sales order corresponding to the purchase order. Furthermore, if a group of suppliers is selected (i.e., the allocation condition is satisfied), the presentation unit 23H presents the user with sales order information (e.g., sales order number and branch number, etc.) indicating the contents of multiple installment sales orders corresponding to the purchase order.

The selection unit 23B then determines whether an inhibiting condition has occurred (S202). If an inhibiting condition has not occurred (NO in S202), the processing ends. On the other hand, if an inhibiting condition has occurred (YES in S202), the selection unit 23B searches among multiple suppliers for at least one alternative supplier that can supply the quantity of goods that was ordered from the failed supplier (S203). In other words, the selection unit 23B searches for an alternative supplier that can supply the quantity of goods included in the requested conditions by the due date of the goods included in the requested conditions.

If there is no alternative supplier (NO in S204), the presentation unit 23H determines that the change conditions are met and presents the change to the sales order information (e.g., a new shipping date) to the user (S205). For example, when goods are shipped in bulk, if there is no supplier who can supply the goods in time for the shipping date from the collection point, the selection unit 23B determines that there is no alternative supplier. Also, when goods are shipped in installments, if there is no supplier who can supply the goods in time for the original shipping date from the affected supplier, the selection unit 23B determines that there is no alternative supplier. If there is no alternative supplier, the presentation unit 23H determines that the change conditions are met.

At this time, the user who is presented with the changes to the sales order information can cancel the order. On the other hand, if the user accepts the change to the shipping date and continues with the order, the creation unit creates a new installment sales order or sales order and creates a purchase order corresponding to the installment sales order or sales order (S206). The ordering unit 23D also cancels the order placed with the affected supplier (i.e., the purchase order) and places an order with an alternative supplier for the quantity of goods that had been ordered from the affected supplier (S207). The presentation unit 23H then presents the new installment sales order or sales order to the user to present the changes to the sales order information. This completes the presentation process. Note that the user order number is not canceled, but the user may change it.

On the other hand, if an alternative supplier is available (YES in S204), the selection unit 23B selects an alternative supplier from among the multiple suppliers (S208). The presentation unit 23H also determines whether the conditions for changing the sales order information are met. If the number of suppliers supplying goods to the user increases or decreases, the presentation unit 23H determines that the conditions for changing the sales order information are met (YES in S209) and presents the changes to the sales order information to the user (S205). If the quantity of goods supplied by each alternative supplier increases or decreases compared to the quantity ordered from the failed supplier, the presentation unit 23H also determines that the conditions for changing the sales order information are met (YES in S210) and presents the changes to the sales order information to the user (S205).

If the conditions for changing the sales order information are not met (NO in S209 and NO in S210), the presentation unit 23H maintains the presentation of the sales order information as is (S211). In other words, the presentation unit 23H does not present changes to the sales order information to the user. The creation unit then creates a purchase order corresponding to the already created installment sales order or sales order (S206). The ordering unit 23D also cancels the order with the failed supplier and places an order with an alternative supplier for the quantity of goods that had been ordered from the failed supplier (S207). This ends the presentation process.

With this presentation process, even if an obstruction condition occurs at the failed supplier and an order is placed with an alternative supplier, if the same number of alternative suppliers as the failed supplier (NO in S209) supply the same quantity of goods as the quantity that the failed supplier was planning to supply (NO in S210), no new installment sales order or sales order will be created. As a result, changes to the sales order information are not presented to the user, and the burden on the user can be reduced when placing an order with an alternative supplier.

[Specific examples]
In the first example, when an inhibiting condition occurs with one supplier A, if the entire ordered quantity is to be ordered from alternative supplier B, the presentation unit 23H maintains the presentation of the sales order information as is. The original sales order is maintained. Then, one purchase order is created for alternative supplier B. Although not specifically explained below, if an inhibiting condition occurs, the purchase order for the supplier A is canceled.

In the first example, if part of the ordered quantity is ordered from alternative supplier B and the remaining quantity is ordered from alternative supplier C, the presentation unit 23H will present the changes to the sales order information to the user. This is because in this case, the number of suppliers supplying goods will increase. The original sales order will be canceled. Then, two split sales orders and two corresponding purchase orders will be created.

In the second example, where the supply supplier group includes the failed supplier A, supplier B, and supplier C, if the entire ordered quantity is ordered from alternative supplier D, the presentation unit 23H maintains the presentation of the sales order information as is. The original three split sales orders are maintained. Then, one purchase order is created for alternative supplier D. The two split sales orders for supplier B and supplier C and the two corresponding purchase orders are also maintained.

In the second example, if part of the ordered quantity is ordered from alternative supplier D and the remaining quantity is ordered from alternative supplier E, the presentation unit 23H presents the changes to the sales order information to the user. This is because in this case, the number of suppliers supplying goods increases. Note that one split sales order for the failed supplier A is canceled. Two split sales orders and two corresponding purchase orders are then created. Furthermore, the two split sales orders for supplier B and supplier C and the two corresponding purchase orders are maintained.

In the second example, if part of the ordered quantity is ordered from alternative supplier B, which is included in the supply supplier group, and the remaining quantity is ordered from alternative supplier C, which is also included in the supply supplier group, the presentation unit 23H presents changes to the sales order information to the user. This is because in this case, the number of suppliers supplying goods will decrease. Note that one installment sales order for the failed supplier A is canceled. Then, two new installment sales orders for alternative supplier B and alternative supplier C, and two corresponding purchase orders are created. Furthermore, the quantities of goods ordered have increased in the two new installment sales orders.

In the second example, if part of the ordered quantity is ordered from alternative supplier B and alternative supplier C, which are included in the supply supplier group, and the remaining quantity is ordered from new alternative supplier D, the presentation unit 23H presents the changes to the sales order information to the user. This is because in this case, the quantity of goods ordered from alternative supplier B and alternative supplier C will increase. Note that one installment sales order for the failed supplier A is canceled. Then, three new installment sales orders for alternative supplier B, alternative supplier C, and alternative supplier D, and three corresponding purchase orders are created.

[Second Modification]
In the second modified embodiment, the creation unit creates multiple purchase orders (FIG. 9) without creating installment sales orders. In the explanation of the second modified embodiment, differences from the first modified embodiment and the first and second embodiments will be explained, and components already described will be given the same reference numerals and their explanations will be omitted. Unless otherwise specified, components with the same reference numerals perform substantially the same operations and functions, and their effects are also substantially the same.

The ordering unit 23D functions as a creation unit, an example of a creation means, that accepts purchase orders for items from users and creates sales orders corresponding to the accepted purchase orders. When a supply supplier group is selected, the creation unit creates multiple purchase orders corresponding to one sales order so that they are linked to the basic sales identification information that identifies the sales orders. Furthermore, when an inhibiting condition occurs, the creation unit creates a new purchase order corresponding to an alternative supplier. The presentation unit 23H then presents the contents of the new purchase order to the user, thereby presenting the changes to the sales order information to the user.

The ordering unit 23D then cancels the order with the failed supplier and places an order with an alternative supplier for the quantity of goods that had been ordered from the failed supplier. Furthermore, if the conditions for changing the sales order information are not met, the presentation unit 23H maintains the presentation of the sales order information as is. On the other hand, if the conditions for changing the sales order information are met, the presentation unit 23H presents the changes to the sales order information to the user. For example, if there is no alternative supplier that can supply the goods by the delivery date, the presentation unit 23H determines that the conditions for changing the sales order information are met, and presents the changes to the sales order information to the user.

[Presentation process]
Referring to FIG. 12 , a presentation process for presenting changes to sales order information to a user when an inhibiting condition occurs will be described. FIG. 12 shows a flowchart of the presentation process for creating a single sales order. First, the ordering unit 23D accepts the purchase order when the user performs an operation to confirm the purchase order. Then, the presentation unit 23H presents the sales order information to the user (S301). For example, when one supplier is selected, the presentation unit 23H presents the user with sales order information indicating the contents of one sales order corresponding to the purchase order. Similarly, when a supply supplier group is selected, the presentation unit 23H presents the user with sales order information indicating the contents of one sales order corresponding to the purchase order.

The selection unit 23B then determines whether an inhibiting condition has occurred (S302). If an inhibiting condition has not occurred (NO in S302), the processing ends. On the other hand, if an inhibiting condition has occurred (YES in S302), the selection unit 23B searches among multiple suppliers for at least one alternative supplier that can supply the quantity of goods that was ordered from the failed supplier (S303). In other words, the selection unit 23B searches for an alternative supplier that can supply the quantity of goods included in the requested conditions by the due date of the goods included in the requested conditions.

If there is no alternative supplier (NO in S304), the presentation unit 23H determines that the change conditions are met and presents the changes to the sales order information (e.g., a new shipping date) to the user (S305). At this time, the user who is presented with the changes to the sales order information can cancel the order. On the other hand, if the user accepts the change to the shipping date and continues with the order, the creation unit creates a new sales order and a purchase order corresponding to the sales order (S306). Furthermore, the ordering unit 23D cancels the order with the failed supplier and places an order with the alternative supplier for the quantity of goods that had been ordered from the failed supplier (S307). The presentation unit 23H then presents the new sales order to the user to present the changes to the sales order information. This ends the presentation process.

On the other hand, if an alternative supplier is available (YES in S304), the selection unit 23B selects an alternative supplier from among the multiple suppliers (S308). Unlike the first variant, a new sales order is not created even if the number of suppliers or the quantity of goods supplied increases or decreases. Therefore, the sales order information is not changed, and the conditions for changing the sales order information are not met. Therefore, the presentation unit 23H maintains the presentation of the sales order information as is (S309). In other words, the presentation unit 23H does not present the changes to the sales order information to the user. The creation unit then creates a purchase order corresponding to the already created sales order (S306). Furthermore, the ordering unit 23D cancels the order with the affected supplier and places an order for the quantity of goods originally ordered from the affected supplier with the alternative supplier (S307). This completes the presentation process.

This type of presentation process prevents new sales orders from being created as long as there is an alternative supplier, even if an obstruction condition occurs with the failed supplier. This means that changes to sales order information are not presented to the user, and even when placing an order with an alternative supplier, the burden on the user is kept from increasing.

The creation unit also creates one sales order corresponding to the purchase order, and one or more purchase orders corresponding to the single sales order. Therefore, even if the allocation conditions are met and a supply supplier group is selected, multiple split sales orders are not created. The presentation unit 23H then presents sales order information indicating the contents of one sales order to the user, even when a supply supplier group is selected. Furthermore, even if an inhibiting condition occurs and an alternative supplier is selected, a new sales order is not created. Therefore, the presentation unit 23H does not need to present changes to the sales order information to the user, and can maintain the presentation of the sales order information.

As a result, unless an inhibiting condition occurs and there is no alternative supplier (i.e., the sales order information change condition is met), the user can inspect the delivered goods as long as they are aware of one sales order. On the other hand, when multiple split sales orders are created, a split sales order number is generated for each split sales order. For example, if each split sales order has a split sales order number, the same number of invoices as the number of split sales orders are issued. As a result, the user must perform inspection work the same number of times as the number of split sales orders. In contrast, when only one sales order is created, only one invoice is issued. The sales order information presented to the user also corresponds to one sales order. Therefore, inspection work is completed only once, reducing the user's management burden. Note that when the creation unit creates a single sales order corresponding to a purchase order, the selection of an alternative supplier in the event of an inhibiting condition occurring may be omitted. Furthermore, when the user selects the order confirmation button 94E in the bulk shipping field 94C, the ordering unit 23D may accept the user's selection of bulk shipping along with the purchase order. This allows items to be transported in bulk, so users only need to receive them once, further reducing the management burden on users.

[Specific examples]
In the first example, when an inhibiting condition occurs with one supplier A, if the entire ordered quantity is to be ordered from alternative supplier B, the presentation unit 23H maintains the presentation of the sales order information as is. The original sales order is maintained. Then, one purchase order is created for alternative supplier B. Although not specifically explained below, if an inhibiting condition occurs, the purchase order for the supplier A is canceled.

In the first example, if part of the ordered quantity is ordered from alternative supplier B and the remaining quantity is ordered from alternative supplier C, the presentation unit 23H maintains the presentation of the sales order information as is. The original single sales order is maintained. Two purchase orders are then created. However, if partial shipments are made by alternative supplier B and alternative supplier C, delivery and inspection work will occur for each supplier, even if the shipping date is the same. Therefore, the presentation unit 23H presents a change to the sales order information (for example, a change to partial shipment) to the user.

In the second example, where the supply supplier group includes the failed supplier A, supplier B, and supplier C, if the entire ordered quantity is to be ordered from alternative supplier D, the presentation unit 23H maintains the presentation of the sales order information as is. The original single sales order is maintained. Then, one purchase order is created for alternative supplier D. The two purchase orders for supplier B and supplier C are also maintained.

In the second example, if part of the ordered quantity is ordered from alternative supplier D and the remaining quantity is ordered from alternative supplier E, the presentation unit 23H maintains the presentation of the sales order information as is. The original single sales order is maintained. Two purchase orders are then created. The two purchase orders for supplier B and supplier C are also maintained.

In the second example, if part of the ordered quantity is ordered from alternative supplier B, which is included in the supply supplier group, and the remaining quantity is ordered from alternative supplier C, which is also included in the supply supplier group, the presentation unit 23H maintains the presentation of the sales order information as is. The original single sales order is maintained. Then, two new purchase orders are created for alternative supplier B and alternative supplier C. Furthermore, the quantities of items ordered have increased in the two new purchase orders.

In the second example, if a portion of the ordered quantity is ordered from alternative supplier B and alternative supplier C, which are included in the supply supplier group, and the remaining quantity is ordered from a new alternative supplier D, the presentation unit 23H maintains the presentation of the sales order information as is. The original single sales order is maintained. Then, three new purchase orders are created for alternative supplier B, alternative supplier C, and alternative supplier D.
