Below, a product management device according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to such an embodiment.

(Hardware configuration)
Fig. 1 is a block diagram showing a hardware configuration of a product management device 1 according to an embodiment. The product management device 1 shown in Fig. 1 includes a storage unit 2, a control unit 3, a communication interface unit 4, and an input/output interface unit 5. An input device 6 and an output device 7 are connected to the input/output interface unit 5. The output device 7 may be a display unit such as a monitor device (including a home television). The input device 6 may be a keyboard device, a mouse device, a microphone device, or a monitor device that cooperates with a mouse device to realize a pointing device function.

The communication interface unit 4 is connected to a wide area network such as the Internet or a private network such as a LAN (Local Area Network).

The storage unit 2 may be, for example, a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), or an SSD (Solid State Drive). The storage unit 2 is provided with a shape master 11, a product type master 12, a template product master 13, a product master 14, and a unit weight master 15, each of which is a storage area.

The storage unit 2 also stores a product management program that enables automatic registration of product information in the product master 14. The storage unit 2 also stores order data that has been entered upon receiving an order.

Predetermined information is registered (stored) in advance in the shape master 11, the product type master 12, and the template product master 13 shown in Fig. 1 and Fig. 2. Specifically, the shape master 11 is set with a numbering rule for a product code, which is a unique number given to a product. The product code numbering rule is a rule to select either "sequential number" or "generated from key information". "Key information" is various information such as the product type, specification, dimensions, customer, inventory management department, inventory status, business segment, and product weight. When "sequential number" is selected, the product code is numbered with "prefix + sequential number". On the other hand, when "generated from key information" is selected, the product code is numbered with the key information specified by the business operator. The sorting order of the key information to be used can also be set. In addition, the character string between each piece of key information can also be specified.

In addition, the shape master 11 is set with a rule for generating a product name. This rule for generating a product name is a rule for selecting either "generate using a template product name" or "generate from key information." When "generate using a template product name" is selected, the product name stored in the template product master 13 is used as the product name of the product. On the other hand, when "generate from key information" is selected, the product name is generated using key information specified by the business operator. The sort order of the key information to be used can also be set. Also, the character string between each piece of key information can be specified.

More specifically, Fig. 3 and Fig. 4 are diagrams showing an example of a setting screen of the shape master 11. As shown in Fig. 3 and Fig. 4, the setting screen of the shape master 11 includes a setting screen for a first tab and a setting screen for a second tab.

Figure 3 is an example of the setting screen of the first tab, which is a setting screen for mainly setting the above-mentioned product code numbering rules and product name generation rules. That is, the setting screen of the first tab is provided with a selection field for the product code setting category, an input field for the number of prefix digits, a selection field for the product name setting category, a selection field for the product variable value setting category, and a selection field for the product code delimiter setting category. In addition, the setting screen of the first tab is provided with, for example, seven input fields for specifying and inputting delimiters to be inserted at the positions that separate the characters or symbols of the product code when individual setting of the product code delimiters is selected. In addition, the setting screen of the first tab is provided with, for example, seven input fields for specifying and inputting delimiters to be inserted at the positions that separate the characters or symbols of the product name when individual setting of the product name delimiters is selected (input fields on the right side of Figure 3).

In the product code setting category selection field, select "1" if you want to generate product codes with consecutive numbers, and select "0" if you want to generate product codes with key information. In the example in Figure 3, "1" has been selected, so the setting to generate product codes with consecutive numbers has been selected. Furthermore, when the setting to generate product codes with consecutive numbers is selected, the product code delimiter setting category is automatically set to the "common" delimiter. When this "common" delimiter is set, "0" is automatically selected for the product code delimiter setting category.

In contrast, if "1" is selected in the product code setting category, which specifies that a product code is to be generated using key information, "1" is automatically selected in the product code separator setting category, indicating that individual setting is possible. In this case, product code separator 1 through product code separator 7 can be input, and the business operator sets the desired product code separator. Note that in this example, a total of seven product code separators can be set, but any number of product code separators may be set, such as four product code separators or nine product code separators.

In the "Number of digits for prefix" input field, enter the desired number of digits for the prefix. In the example in Figure 3, "2 digits" is entered. In the "Product name setting" selection field, "0" is selected if the product name is generated as a consecutive number, and "1" is selected if the product name is generated with key information. In the example in Figure 3, "1" is selected, so the setting to generate the product name with key information is selected. When the product name is generated with key information, as shown on the right side of Figure 3, the individual setting of "1" is automatically set in the product name separator setting field, and product name separator 1 to product name separator 7 can be entered. The business operator sets the product name separator by entering the desired characters in the product name separator 1 to product name separator 7 input fields. In the example in Figure 3, ": (colon)" is set for product name separator 1, and "x (multiplication sign)" is set for product name separator 2 to product name separator 7.

If you select to generate product names using "sequential numbers," the product name separator setting category is automatically set to "0" ("common"). In this case, the product name separator will be separated using a specified common character.

Next, FIG. 4 shows an example of the setting screen for the second tab, which is a setting screen for setting various information to be included in the product information to be registered in the product master 15. In the example of FIG. 4, the product dimensions, customer, inventory management department, inventory status, business segment, and shape classification can be set. It is also possible to set the unit weight of products such as coils stored in the unit weight master 15.

For dimension settings, it is possible to set "use/non-use (use/non-use)", "name", "input type (numeric, character string)" and the number of digits for dimension 1 to dimension 8. For shape category settings, it is possible to set "use/non-use (use/non-use)" and "number of digits for character string" for shape category 1 to shape category 10. Note that names may be set all at once based on a separate master.

The example in Figure 4 is an example of a setting in which dimensions, customer, inventory management department, inventory status, and business segment are included in the product information (usage category = used), but shape category is not included in the product information (usage category = not used). This example in Figure 4 is also an example in which the dimensions of an H-shaped steel, which is an example of a product, are included in the product information. H-shaped steel is formed by connecting the approximate centers of a pair of flat flanges via a flat web, so that the cross section is approximately H-shaped.

Dimension H indicates the length between each flange. Dimension B indicates the width of each flange. Dimension t1 indicates the thickness of the web. Dimension t2 indicates the thickness of each flange. Dimension r indicates the curvature of the connection between the web and each flange. These dimensions are set numerically. Of these, dimensions H and B are set as three-digit numbers, while dimensions t1, t2, and r are each set as two-digit numbers. The numerical unit code for dimensions H, B, t1, t2, and r is each set to "12 mm." Also, in the example of Figure 4, the "standard" dimension is set to "Use." This "standard" is set as a 10-digit character string.

The order of items when searching for products is set to dimension H, dimension B, dimension t1, dimension t2, dimension r, and specification. The order of items as product names is set to specification, dimension H, dimension B, dimension t1, and dimension t2.

The example in FIG. 4 is an example in which shape categories 1 to 4 are set to "Use". In shape category 1, the character string "Consumer" is set as a character string length of "5 digits", and in shape category 2, the character string "Inventory management department" is set as a character string length of "5 digits". In shape category 3, the character string "Inventory status" is set as a character string length of "1 digit", and in shape category 4, the character string "Business segment" is set as a character string length of "5 digits". Note that the character string "Unit weight" may also be set in shape category 6, etc.

As a result, the product management device 1 of this embodiment automatically creates a product master 14 using key information such as the customer, inventory management department, inventory status, business segment, and unit weight in addition to the type, specification, and dimensions.

On the other hand, the product type master 12 contains settings for whether or not to use automatic product numbering, the association between the product type and the shape master 11, and the product code prefix. The template product master 13 also contains settings for the product names, etc. that are automatically created.

(Functional configuration of product management device)
Next, the control unit 3 executes the product management program stored in the memory unit 2, and thereby functions as an input processing unit 21, a product search unit 22, a discrimination unit 23, a data generation unit 24, a display control unit 25, and a memory control unit 26.

The display control unit 25 displays various input screens, such as an order input screen, quotation input screen, order input screen, sales input screen, order input screen, purchase input screen, processing instruction input screen, processing input screen, and movement input screen, via the output device 7, which is an example of a display unit. Based on the product type input via the input screen, the discrimination unit 23 refers to the product master 14, which stores product information including at least the product type and product dimension information, and discriminates whether dimension information corresponding to the input product type is registered.

When the discrimination unit 23 gives a discrimination result indicating that the dimensional information is not registered in the product master 14, the storage control unit 26 automatically registers (automatically stores) the product dimensional information input via the input screen, the product code generated based on the dimensional information, and the product information including the product variety in the product master 14. The data generation unit 24 generates order data based on the various information input via the order input screen.

The input processing unit 21 acquires various information input via the input screen. The product search unit 22 searches the product master 14 for product information on a product that corresponds to the variety input via the input screen.

The storage control unit 26 also registers (stores) in the product master 14 the selected product code from among the product codes generated based on the serial number or the dimensional information, as part of the product information. The storage control unit 26 also registers in the product master 14 the selected product name from among the template product name stored in the template product master 13 or the product name generated based on the dimensional information stored in the product master 14, as part of the product information.

Furthermore, the memory control unit 26 registers the information entered via the input screen, such as the customer, inventory management department, inventory status, business segment, and unit weight of the product, in the product master 14, including the product information.

(Automatic registration process for product master)
Fig. 5 is a schematic diagram for explaining the automatic registration operation of product information when a product order is input in the product management device 1 of the embodiment. The control unit 3 executes the automatic registration operation of the product information shown in Fig. 5 based on the product management program stored in the storage unit 2. That is, in Fig. 5, when the business operator performs an operation to instruct the start of order input (step S1), the display control unit 25 displays the product search screen shown in Fig. 6 via the output device 7 (step S2).

As shown in FIG. 6, the product search screen has an input field for the variety. The business operator inputs the variety code of the desired variety, such as "H001", into this input field. The product search unit 22 searches the product master 14 based on the input variety code, such as "H001". The discrimination unit 23 discriminates whether various product information, such as dimensional information, corresponding to the input variety code, "H001", has already been registered in the product master 14.

When the discrimination unit 23 obtains a discrimination result indicating that various product information such as dimension information corresponding to the input variety code has already been registered in the product master 14, the display control unit 25 reads out various product information such as dimension information corresponding to the input variety code from the product master 14. Then, the display control unit 25 displays, for example, the read out various product information as a search result in an input field corresponding to the product search screen. The example in FIG. 6 is an example in which the above-mentioned dimensions H, B, t1, t2, and r have already been registered as product information for the variety code "H001", and the customer code of the customer such as "J001", the inventory management department code of department A such as "B001", inventory information such as "good product", and the business segment such as "Z01" are associated and registered.

Upon recognizing such search results, the business operator operates the Confirm button 50 (F11: Confirm). This causes the display control unit 25 to display an order entry screen reflecting the various product information displayed on the product search screen. The business operator enters other necessary input items into this order entry screen in addition to the above-mentioned product information. The input processing unit 21 acquires the various information entered into the order entry screen, and the data generation unit 24 generates order data based on the various information acquired from the order entry screen. The memory control unit 26 stores the generated order data in the memory unit 2 (step S4). This order data is recorded in accounting at a predetermined timing.

In response to this, the product master 14 is searched based on the input variety code, and if the discrimination unit 23 obtains a discrimination result indicating that various product information such as dimension information corresponding to the input variety code is not registered in the product master 14, the display control unit 25 displays a product search screen with input fields other than the input variety code left blank. That is, in the example of Figure 6, the product search screen is displayed with input fields such as dimensions, specifications, customer, inventory management department, inventory status, and business segment left blank.

The business operator inputs product information such as dimension H, dimension B, dimension t1, dimension t2, dimension r, customer code, inventory management department code, inventory information, business segment, and unit weight such as coil unit weight or millimeter unit weight into each blank input field, as shown in FIG. 6, and presses the Confirm button 50. When the Confirm button 50 is pressed, the data generation unit 24 refers to the shape master 11, etc., and recognizes the above-mentioned product code numbering rules and product name generation rules, etc. Then, the data generation unit 24 generates product information by adding the product code numbered according to the product code numbering rules and the product name generated according to the product name generation rules to various information such as the input variety code, dimension, specification, customer, inventory management department, inventory status, and business segment. The storage control unit 26 registers (stores) the generated product information in the product master 14 (step S3).

Figure 7 is a diagram showing an example of product information generated in this way. As shown in Figure 7, the data generation unit 24 generates product information including the product code, product name, variety code, dimensions 1 to 8, and shape categories 01 to 10. The product code is generated based on the product code numbering rules set in the shape master 11, as explained using Figure 3. The example in Figure 3 is an example in which "consecutive numbers" are set as the product code numbering rule. In this case, the data generation unit 24 automatically assigns a consecutive number such as "S00001" as shown in Figure 7 and adds it to the product information.

As explained with reference to FIG. 3, the product name is also generated based on the product name generation rules set in the shape master 11. The example in FIG. 3 is an example in which "Generate from key information" is selected as the product name numbering rule. In this case, the data generation unit 24 refers to the "Product name sorting order" in the shape master 11 shown in FIG. 4. In the example of FIG. 4, a rule is set to generate the product name by arranging the key information in the following order: specification, dimension H, dimension B, dimension t1, and dimension t2. The data generation unit 24 also refers to the product name separator setting section shown in FIG. 3. In the example of FIG. 3, the first product name separator is set to ": (colon)" and the subsequent product name separators are set to "x (multiplication sign)".

For this reason, the data generation unit 24 generates a product name of "H-100: 100 x 200 x 10.5 x 12" by arranging in order a standard such as "H-100", a product name separator ":", the dimension H of "100", the dimension B of "x" and "200", the dimensions t1 of "x" and "10.5", and the dimensions t2 of "x" and "12", and adds this to the product information.

This allows order data to be generated from product information such as dimension H, dimension B, dimension t1, dimension t2, dimension r, customer code, inventory management department code, inventory information, business segment, and unit weight (coil weight or millimeter weight) that was input when the order was received, and the product information is automatically registered (stored) in the product master 14, forming the product master 14.

As described above, when the Confirm button 50 is operated, the various product information on the product search screen is reflected on the order input screen, and the generated order data is stored in the memory unit 2.

(Effects of the embodiment)
In the steel industry, product masters are often set by type, standard, and dimension, and it has been difficult to register these in the product master before trading the product, but the product management device 1 of the embodiment can automatically create a product master 14 in accordance with the input contents after the transaction contents are confirmed, for example, when an order is entered. This makes it easy to register product information in the product master 14. In other words, the product master 14 can be easily created.

In addition, the product management device 1 of the embodiment is capable of registering product information, including customer, inventory management department, inventory status (materials, work in progress, finished product), business segment, and unit weight, in addition to product type, specification, and size, in the product master 14. This allows product management based on customer, inventory management department, inventory status, business segment, or unit weight. In addition, since product management is possible based on information such as customer other than product type, specification, and size, it becomes possible to distinguish products with different uses in the system.

In addition, in actual business, different customers may require different quality or specifications even for products of the same size. In the case of the product management device 1 of the embodiment, the products to be managed for each customer can be registered separately in the product master 14, so that the inventory of products for a specific customer can be managed separately from others. This makes it possible to reduce human error when handling products.

In addition, by including the business segment in the product information (by setting the business segment as a key), inventory analysis and management can be performed by business. Conventionally, it was necessary to separate business segments by using separate systems or warehouses. In contrast, with the product management device 1 of the embodiment, it is possible to separate products by business segment.

In addition, the unit weight master 15 allows the coil unit weight or millimeter unit weight to be included in the product information and registered in the product master 14, making it possible to manage products based on unit weight.

[Contribution to the United Nations-led Sustainable Development Goals (SDGs)]
This embodiment can contribute to improving business efficiency and promoting appropriate management decisions by companies, thereby making it possible to contribute to Goals 8 and 9 of the SDGs.

In addition, this embodiment can contribute to reducing waste and promoting paperless and electronic systems, which can contribute to the achievement of SDGs Goals 12, 13, and 15.

In addition, this embodiment can contribute to strengthening control and governance, making it possible to contribute to Goal 16 of the SDGs.
