Description

  The present invention relates to a component supply management device that manages the supply of components to a production site.

Conventionally, a system for supplying parts from a warehouse to a production site (for example, a production line) has been developed (see, for example, Patent Document 1). This patent document 1 discloses a system in which production results at a production site (information on the number of products produced) are input from a terminal and parts are supplied based on the production results.
Japanese Patent Laid-Open No. 4-125205 (pages 6-8, FIG. 12, etc.)

  However, if the number of products produced is manually input from the terminal, the human load becomes excessive, and it is difficult to increase the frequency of input. Therefore, in the above-mentioned patent document 1, the number of parts used on the production site is logically calculated based on the production plan for the period from the manual input to the next manual input. . However, in this case, even if some trouble occurs at the production site between the input of the production results from the terminal and the next input, and such production is stopped due to the trouble, such information is in real time. Since it is not transmitted, a part delivery instruction is issued based on the production plan, and a situation may occur in which a large amount of parts are invented at the production site.

  In addition, from the start of production at the production site, that is, from the start process of production to the end of production, that is, from the final process of production, usually, parts are mounted in a plurality of processes. In such a case, the number of parts used in the first production process is different from the number of parts used in the final production process. For example, 100 production objects have already passed and 100 parts have been used at the first process point of production, while only 50 production objects have passed at the final production point. It can happen that only 50 parts are used. In such a case, if the instruction to issue each part only by the number of manufactured products, the needs of parts related to the use of each part from the first production process to the final production process at the production site, I can't handle it finely. Specifically, if parts are supplied in accordance with the number of parts required in the first production process, the inventory at the production site may be increased as a whole. On the other hand, if parts are supplied in accordance with the number of parts required in the final production process, there may be a shortage of parts in the first production process. This can be particularly problematic when the production involves a large number of steps and many types of parts are required.

The present invention has been made to solve the above problems, and one of its purposes is to supply a necessary quantity of parts from a warehouse when necessary based on information from a production site. It is to provide a component supply management device that manages the supply of components.
Another object of the present invention is to provide a component supply management device and the like that can reduce the inventory quantity of components at the production site as a whole by finely responding to the use of each component at the production site. .

In order to achieve the above object, a parts supply management device according to the present invention includes a production information receiving unit that receives production information that is information related to production, and information indicating the number of each part used or scheduled to be used on the production site. A used part number information storage unit that stores used part number information, and a used part number information update unit that updates the used part number information based on the production information received by the production information receiving unit, A supply information storage unit storing supply information that is information including at least a delivery quantity indicating the number of parts supplied from the warehouse where the parts are stored to the production site, the supply information, and the number of used parts information On the basis of the on-site inventory quantity calculation unit that calculates the inventory quantity of each part in the production site, and based on the on-site inventory quantity calculated by the on-site inventory number calculation unit, A supply instruction output unit that outputs an instruction regarding the supply of parts from a warehouse to the production site, and the delivery according to the supply of parts from the warehouse to the production site based on the instructions output by the supply instruction output unit A delivery quantity update unit for updating the quantity.

  With such a configuration, the supply of parts can be managed so that a necessary quantity of parts is supplied to the production site when necessary. As a result, for example, it is possible to automatically and quickly respond to changes in the production speed at the production site and the occurrence of trouble, and situations or parts that excessively increase the number of parts inventory at the production site. It is possible to prevent a situation where out of stock occurs.

  In the component supply management device according to the present invention, the production information is information at a plurality of production stages related to the fact that the production target has passed a predetermined production stage at the production site, and the number information of used parts is updated. The unit may update the used part number information for each part used in the plurality of production stages, and the supply instruction output unit may output the instruction for each part.

  With such a configuration, the supply of parts can be managed so that an appropriate quantity of parts required in each production stage is supplied from the warehouse. As a result, compared with the case where uniform parts supply management is performed in all production stages, the inventory quantity of parts at the production site can be compressed as a whole.

In the component supply management device according to the present invention, an inventory allocation unit that allocates inventory to inventory information that is information related to inventory in the warehouse based on the number of on-site inventory calculated by the on-site inventory number calculation unit The supply instruction output unit may output an instruction related to the supply of the component according to the quantity allocated by the inventory allocation unit.
With such a configuration, it is possible to instruct parts supply according to stock. In addition, parts are instructed based on the stock status, and for example, complicated and unnecessary parts supply processing from the warehouse to the production site can be avoided.

  According to the component supply management device or the like according to the present invention, the supply of components can be managed so as to supply a necessary quantity of components when necessary.

(Embodiment 1)
An information processing apparatus according to Embodiment 1 of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration of a component supply management apparatus according to the present embodiment. In FIG. 1, the component supply management apparatus according to the present embodiment includes a production information receiving unit 10, a used component number information storage unit 11, a used component number information update unit 12, a supply information storage unit 13, and an on-site inventory number. A calculation unit 14, an inventory information storage unit 15, an inventory information management unit 16, an inventory allocation unit 17, a supply instruction output unit 18, and a delivery quantity update unit 19 are provided.

The production information receiving unit 10 receives production information. Here, the production information is information relating to production. This production information is information used to calculate the number of parts used at the production site. Note that the use of parts at a production site means that parts are used to produce a product. The production information includes, for example, information indicating the number of products produced, information indicating that the production target has passed a predetermined production stage, and the number of each part used or scheduled to be used at the production site. There is information to show. Here, in this embodiment, the production information is information indicating that the production object has passed a predetermined production stage (for example, a pallet passing signal, a signal indicating completion of transfer of the robot, etc.) The case of information at a plurality of production stages will be described. That is, the production information in the present embodiment is information indicating that a production object has passed in a plurality of component supply stations for a process of assembling components, for example. This information may be, for example, information indicating that the production object has passed a predetermined production stage simply by a predetermined pulse or the like, or indicates a cumulative value of the production object that has passed the predetermined production stage. It may be information. The production information receiving unit 10 may receive production information input from a predetermined input device (for example, a keyboard or a mouse), or may receive transmitted production information. When production information is transmitted, the transmission timing may be periodic, or the timing due to the occurrence of a predetermined event (for example, 10 production objects have passed). It does not matter at any timing. Further, the production information may be transmitted unilaterally from another device or the like, or may be transmitted by a request from the production information receiving unit 10. The production site is a production site. Examples of this production method include line production and cell production, and any method can be used. In the present embodiment, a case where production is performed by line production will be described. Therefore, the production site is sometimes referred to as a production line.

  The used component number information storage unit 11 stores used component number information. Here, the used part number information is information indicating the number of each part used or scheduled to be used at the production site. The used component number information storage unit 11 can be realized by a predetermined recording medium (for example, a magnetic disk, an optical disk, a semiconductor memory, etc.). The storage by the used component number information storage unit 11 may be a temporary storage such as a RAM or a long-term storage such as a magnetic disk.

  The used component number information update unit 12 updates the used component number information stored in the used component number information storage unit 11 based on the production information received by the production information receiving unit 10. This update is performed so that the number of parts indicated by the used part number information is the number of parts used at the production site. Therefore, the used component number information is updated by, for example, adding the number of each component used or scheduled to be used within a predetermined period to the number of components indicated by the used component number information. Note that “the number of parts used” or “the number of parts planned to be used” indicates that, for example, the production information indicates that the production object has passed a predetermined production stage. This is because the information may be the number of parts actually used or the number of parts scheduled to be used depending on the position of the production stage. When the production information is information related to the number of production objects, the used part number information update unit 12 converts the number of production objects into the number of parts. For example, when the production information indicates the number of products produced and two parts are used in the product, the number of parts used is received when production information indicating that one product has been produced is received. Two is added to the number of parts used in the information.

  The supply information storage unit 13 stores supply information. Here, the supply information is information including at least the delivery quantity. The outgoing quantity is a quantity indicating the number of parts supplied from the warehouse where the parts are stored to the production site. That is, the number of parts supplied from the warehouse to the production site can be known from this supply information. The supply information storage unit 13 can be realized by a predetermined recording medium (for example, a magnetic disk, an optical disk, a semiconductor memory, etc.).

  The on-site inventory number calculation unit 14 calculates the on-site inventory number based on the supply information stored in the supply information storage unit 13 and the used component number information stored in the used component number information storage unit 11. Here, the on-site inventory number is the theoretical inventory number of each part at the production site. The number of parts in the vicinity of the production line or the like for production can be known from the number of on-site inventory. In the present embodiment, the calculated on-site inventory number is stored in the supply information storage unit 13. That is, the supply information includes the number of on-site inventory.

  The inventory information storage unit 15 stores inventory information. Here, the inventory information is information relating to warehouse inventory. That is, it is possible to know how many parts are stored in the warehouse by this inventory information. In addition, the inventory information may include the position in the warehouse where each part is stored, the date and time when each part was received in the warehouse, and the like. The inventory information storage unit 15 can be realized by a predetermined recording medium (for example, a magnetic disk, an optical disk, a semiconductor memory, etc.).

  The inventory information management unit 16 manages the inventory information stored in the inventory information storage unit 15. That is, when a part is received in the warehouse, the inventory information management unit 16 adds information regarding the received part to the inventory information. By managing the inventory information by the inventory information management unit 16, the inventory information represents the actual inventory status in the warehouse.

  The inventory allocation unit 17 allocates inventory to the inventory information based on the on-site inventory number calculated by the on-site inventory number calculation unit 14. In other words, when the number of on-site inventory of a part falls below a predetermined threshold value (“0” in the present embodiment), inventory allocation for that part is performed. Here, performing the inventory allocation for the inventory information means updating the inventory information. In addition, the inventory allocation unit 17 passes information including a component identifier (component code) for identifying the allocated component and the number of allocations to the supply instruction output unit 18 and the outgoing quantity update unit 19. . Here, the information passed to the supply instruction output unit 18 may include information indicating the managed position of the part in the warehouse.

  The supply instruction output unit 18 outputs an instruction related to the supply of parts from the warehouse to the production site based on the number of on-site inventory. Here, the supply instruction output unit 18 outputs the supply instruction by indirectly using the number of on-site inventory. That is, when the supply instruction output unit 18 receives the information including the part identifier for identifying the allocated part and the number of the reserved part from the inventory allocating part 19, the supply instruction output part 18 receives the information from the warehouse based on the information. Outputs instructions for supplying parts to The instruction includes, for example, information indicating the parts instructing supply and the number of the parts, and information indicating the managed position of the parts in the warehouse. Here, the output may be, for example, display on a display device (for example, a CRT or a liquid crystal display), or transmission to a predetermined device (for example, a distribution facility control device that manages a warehouse) via a communication line. It may be printed by a printer, or output by sound from a speaker. The supply instruction output unit 18 may or may not include an output device (for example, a display device or a printer). The supply instruction output unit 18 may be realized by hardware, or may be realized by software such as a driver that drives these devices. The supply of parts to the production site according to the supply instruction output by the supply instruction output unit 18 may be an automatic supply made by an automatic warehouse or the like, or all or a part of the supply may be human. Work may be included.

The delivery quantity update unit 19 updates the delivery quantity stored in the supply information storage unit 13 in accordance with the supply of parts from the warehouse to the production site. The parts are supplied from the warehouse to the production site based on the instruction output by the supply instruction output unit 18. Here, in the present embodiment, the delivery quantity is updated by the delivery quantity update unit 19 from the inventory allocation unit 17 as described above, the part identifier for identifying the allocated part, and the number of the allocation. And receive information including
It is assumed that the processing is performed according to the number of parts included in the information. That is, the delivery quantity is updated based on the quantity allocated by the inventory allocation unit 17. It should be noted that the output quantity may be updated according to the number of parts included in the instruction output by the supply instruction output unit 18, or the part included in the report that the parts are supplied from the warehouse to the production site. It may be made according to the number of.

Next, the operation of the component supply management apparatus according to the present embodiment will be described with reference to the flowchart of FIG.
(Step S101) The production information receiving unit 10 determines whether production information has been received. If the production information is received, the production information is passed to the used part number information update unit 12 and the process proceeds to step S102. If not, the process proceeds to step S103.

(Step S102) The used component number information update unit 12 updates the used component number information based on the production information. Then, the process returns to step S101.
(Step S103) The on-site inventory quantity calculation unit 14 determines whether or not there is an update of the used part number information and the delivery quantity included in the supply information. If there is an update, the process proceeds to step S104, and if not, the process proceeds to step S106.

  (Step S104) The on-site inventory quantity calculation unit 14 calculates the on-site inventory quantity based on the used part number information and the supply information. For example, the on-site inventory quantity calculation unit 14 calculates the on-site inventory quantity by subtracting the used parts number indicated by the used parts quantity information from the delivery quantity included in the supply information.

  (Step S105) The on-site inventory quantity calculation unit 14 accumulates the calculated on-site inventory quantity in the supply information stored in the supply information storage unit 13. That is, except when writing for the first time, it is updated by overwriting the on-site inventory quantity. Then, the process returns to step S101.

(Step S106) The inventory allocation unit 17 determines whether or not the number of on-site inventory corresponding to any of the parts has become 0 or less. If the value is 0 or less, the process proceeds to step S107. If not, the process proceeds to step S110.
(Step S107) The inventory allocation unit 17 allocates inventory for the inventory information. Then, the information including the part identifier indicating the part for which the inventory is reserved and the quantity thereof is passed to the supply instruction output unit 18 and the delivery quantity update unit 19.

(Step S <b> 108) The supply instruction output unit 18 outputs an instruction to supply a part based on information including the part identifier indicating the part for which the inventory has been allocated received from the inventory allocation unit 17 and the quantity thereof. .
(Step S109) The outgoing quantity update unit 19 updates the outgoing quantity included in the supply information based on the information including the part identifier indicating the part that has been reserved and received from the inventory allocation part 17 and the quantity. . Then, the process returns to step S101.

  (Step S110) A production management unit (not shown) determines whether or not the plan has been completed. Here, completion of the plan means that all the supply parts have been supplied. When the planning is finished, the series of processing related to component supply management is finished. On the other hand, if the plan is not finished, the process returns to step S101.

Next, the operation of the component supply management apparatus according to this embodiment will be described using a specific example. In this specific example, as shown in FIG. 3, a parts supply management device 1, a production facility control device 2, and a physical distribution facility control device 3 constitute a production system, which is a wired or wireless communication line. 4 is connected. Here, the production facility control device 2 is a device that controls production at the production site. It is assumed that production information is periodically transmitted from the production facility control device 2 to the component supply management device 1. The distribution facility control device 3 is a device that controls the supply of parts from the warehouse to the production site. By sending a parts supply instruction from the parts supply management device 1 to the physical distribution equipment control device 3, the parts are supplied from the warehouse to the production site.

  FIG. 4 is a diagram for explaining the outline of the production line in this specific example. In the production line in this specific example, the production object is conveyed by the belt conveyor. Three stations ST101, ST102, and ST103 are provided. In each station, the component 1, the component 2-1, the component 2-2, and the component 3 are assembled, and the product is completed. 4 shows only one production line, a plurality of production lines may exist at the production site. Further, in this production line, a production counter is provided for each station, and the production counter is incremented by 1 each time a production object passes through the station. That is, the production counter counts the cumulative value of the production object that has passed the predetermined production stage. This production counter is controlled by the manufacturing facility control device 2, and the production count for each station is transmitted to the component supply management device 1 every 30 seconds. The production count transmitted is the production information described above.

  FIG. 5 is a diagram illustrating an example of production information (production count) transmitted from the manufacturing facility control device 2 to the component supply management device 1 at a certain timing. Here, for convenience of explanation, the table format is used. However, the actually transmitted production information may be a format in which a station identifier for identifying a station and a production count value are alternately sent. May be sent in the order of station identifiers ST101, ST102, ST103, and the format is not limited. In the production information, the value of the production count is different for each station, but this is caused by the existence of a production object between the stations. That is, there are about 20 production objects between the station ST101 and the station ST102.

  When the production information receiving unit 10 receives the production information shown in FIG. 5, the production information receiving unit 10 passes the production information to the used component number information updating unit 12 (step S101). The used part number information updating unit 12 holds part configuration information of the product shown in FIG. Here, in the part configuration information of the product shown in FIG. 6, the product identifier is an identifier for identifying the product, the part code is an identifier for identifying the part, and the number is used in the production of the product. It is the number of parts, the line is an identifier for identifying the production line on which the product is produced, and the station identifier is an identifier indicating the station where the corresponding part is used. Therefore, when the used part number information update unit 12 receives the production information shown in FIG. 5, 120 parts 1 are used, 100 parts 2-1 and 2-2 are used, and part 3 is 160. It is possible to calculate that the number has been used. Then, the used component number information update unit 12 updates the used component number information (step S102). As a result, it is assumed that the number of used parts information is as shown in FIG. Here, in the used component number information shown in FIG. 7, the component code and the number of used components are associated with each other.

When the number of used parts information is updated, the on-site inventory number calculation unit 14 detects that fact (step S103), and from the output quantity corresponding to each part included in the supply information, to each part indicated by the used part number information. The number of on-site inventory is calculated by subtracting the corresponding number of used parts (step S104). Then, the on-site inventory quantity calculation unit 14 overwrites the calculated on-site inventory quantity on the supply information. FIG. 8 is a diagram showing the supply information updated as described above. In the supply information shown in FIG. 8, the line, the station identifier, the part code, the planned number, the outgoing quantity, and the on-site inventory quantity are associated with each other. The number of plans is set according to the number of production plans by a production management unit (not shown). Here, the plan is to produce 500 products, and the planned number for each part is set according to the plan.

  Here, it is assumed that production in the production line A has progressed and the number of on-site inventory of the part 2-2 becomes zero. Then, this is detected by the inventory allocation unit 17 (step S106), and the inventory allocation unit 17 refers to the inventory information. Here, it is assumed that the inventory information is as shown in FIG. In the inventory information shown in FIG. 9, information indicating the inventory position in the warehouse by “column”, “ream”, “stage”, information indicating the part code, the number of inventory, and the date and time when the part was received in the warehouse. Are associated with each other. Since 100 parts 2-2 are stored in the first row and the first stage of the fourth column, the inventory allocation unit 17 allocates 100 of the inventory (step S107). That is, the record regarding the part 2-2 is deleted from the inventory information, or the number of inventory of the record is set to zero.

  In addition, the inventory allocation unit 17 passes the fact that the inventory allocation of 100 parts 2-2 has been performed to the outgoing quantity update unit 19 and uses it in the first column of the fourth column for use in the station ST102 of the production line A. Then, the supply instruction output unit 18 is passed to the effect that the inventory of 100 parts 2-2 stored in the first stage has been allocated. Then, the supply instruction output unit 18 issues an instruction to supply 100 parts 2-2 stored in the first row and the first stage of the fourth row to the station ST102 of the production line A. 3 (step S108). Then, 100 parts 2-2 stored in the first row and the first stage in the fourth row are supplied to the production line A by the control of the distribution facility control device 3. Further, the outgoing quantity update unit 19 adds 100 to the outgoing quantity of the part 2-2 (step S109). As a result, the on-site inventory quantity calculation unit 14 detects that the delivery quantity has been updated, and updates the on-site inventory quantity. FIG. 10 is a diagram showing the supply information updated in this way. Here, it is assumed that the inventory allocation unit 17 allocates inventory in a range where the delivery quantity satisfies the planned quantity when the inventory is allocated.

  In the production line A, when the delivery quantity corresponding to each part becomes the same as the planned number, the production management unit (not shown) detects this, and the series of processing is finished assuming that the plan is finished (step S110). In addition, here, the case where the plan is finished when the outgoing quantity and the planned number become the same has been described, but the outgoing quantity is equal to or more than the planned quantity and the on-site inventory quantity is 0. The plan may be finished when

  In this specific example, the case where the used component number information update unit 12 has the product component configuration information has been described. However, when the production information is information indicating the number of components used at the production site. The used component number information updating unit 12 may not have the product component configuration information.

  Further, in this specific example, the case where inventory allocation is performed in units of inventory positions has been described. For example, when there is 100 inventory at a certain inventory position, but the number required for allocation is 50 Of these, 50 stocks are allocated, and the number of stocks is updated to 50 in the record corresponding to the stock information.

  Further, in this specific example, the case where the threshold value of the number of on-site inventory is “0” has been described, but considering the number of parts used from when the supply instruction is output until the parts are supplied. One or more threshold values may be set.

  Further, in this specific example, the case where the supply instruction output unit 18 outputs an instruction including the part code and quantity of the parts supplied from the warehouse to the production site as the supply instruction has been described. Only the position of may be included. For example, only the information “the fourth row in the first column, the first stage” indicating the inventory position and the position at the production site where the part is supplied may be included in the instruction.

  Further, when the supply destination at the production site can be specified (for example, when a specific part is used only at a predetermined station on a predetermined line), the supply of the part is instructed by the supply instruction output unit 18. The tip may not be included.

  As described above, according to the parts supply management device according to the present embodiment, the number of on-site stocks is calculated based on production information received in real time, and parts from the warehouse to the production site are calculated according to the number of on-site stocks. By performing the supply instruction, a necessary quantity of parts can be supplied from the warehouse when necessary. In other words, it is possible to supply parts in a just-in-time manner that keeps parts from being insufficient while minimizing the inventory of parts at the production site. Further, even when the production speed at the production site is changed, it can be automatically handled easily.

  Further, when some trouble occurs at the production site and the production is stopped, the number of used parts does not decrease even when the production information is received, so that the supply instruction is not given. As a result, it is possible to prevent a situation in which an excessive inventory of parts at the production site occurs during a trouble.

  Further, the production information receiving unit 10 receives production information from a plurality of production stages (stages), and the used part number information updating unit 12 updates the used part number information for each part used in each production stage, and supplies instructions. When the output unit 18 issues a supply instruction for each part, the use of each part at the production site can be handled in detail for each part. As a result, the inventory quantity of parts at the production site can be compressed as a whole. For example, even when there is a difference between the demand for parts in the first process of production on the production line and the demand for parts in the final process of production, it is possible to supply appropriate parts for each demand.

  Further, in the present embodiment, the provision of the inventory allocating unit 17 that allocates inventory to the inventory information is provided, so that it is possible to instruct supply of parts according to the inventory. As a result, it is possible to avoid complicated parts supply processing and the like by allocating inventory in units of inventory positions. Specifically, for example, with regard to the inventory allocation of parts by the inventory allocation unit 17, an upper limit and a lower limit of the quantity of parts are set, and a part stored in one inventory position within the range is set. Reserve inventory. By doing so, for example, it is possible to reduce inventory allocation across two inventory positions, and it is possible to smoothly supply parts from the warehouse to the production site.

(Embodiment 2)
A component supply management apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. The parts supply management device according to the present embodiment does not allocate the inventory, but only outputs a supply instruction. In addition, according to the number of parts supplied to the production site according to the supply instruction, the number of goods delivered Is to be updated.

  FIG. 11 is a block diagram showing the configuration of the component supply management apparatus according to this embodiment. In FIG. 11, the component supply management apparatus according to the present embodiment includes a production information receiving unit 10, a used component number information storage unit 11, a used component number information update unit 12, a supply information storage unit 13, and an on-site inventory quantity. A calculation unit 14, a delivery quantity update unit 19, a supply instruction output unit 21, and a supply quantity reception unit 22 are provided. The configuration and operation other than the supply instruction output unit 21 and the supply quantity reception unit 22 are the same as those in the first embodiment, and the description thereof is omitted.

The supply instruction output unit 21 outputs an instruction regarding supply of parts from the warehouse to the production site based on the number of on-site inventory. The supply instruction output unit 21 according to the present embodiment outputs a supply instruction by directly referring to the number of on-site inventory stored in the supply information storage unit 13. Note that, unlike the supply instruction output unit 18 according to the first embodiment, the supply instruction output unit 21 does not receive the quantity of parts that have been allocated, so that the on-site inventory number included in the supply information is predetermined. For a component that is less than or equal to the threshold value (which is “0” in this embodiment), it is possible to simply output an instruction to supply the component, or supply the component in a predetermined quantity. An instruction to do so may be output. Similar to the supply instruction output unit 18, the output may be, for example, display on a display device, transmission to a predetermined device via a communication line, printing by a printer, or output by sound from a speaker. But you can. The supply instruction output unit 21 may or may not include a device that performs output (for example, a display device or a printer). The supply instruction output unit 21 may be realized by hardware, or may be realized by software such as a driver that drives these devices.

  The supply quantity receiving unit 22 receives the supply quantity. Here, the supply quantity is the number of parts supplied from the warehouse to the production site or to be supplied. The supply quantity receiving unit 22 may receive a supply quantity input from a predetermined input device, or may receive a transmitted one. When the supply quantity is transmitted, the transmission timing may be periodic, or the timing according to the occurrence of a predetermined event (for example, supply of parts from the warehouse to the production site). However, the timing is not important.

Next, the operation of the component supply management apparatus according to this embodiment will be described with reference to the flowchart of FIG. Note that processes other than steps S201 to S204 are the same as those in the first embodiment, and a description thereof will be omitted.
(Step S201) The supply instruction output unit 21 determines whether or not the number of on-site inventory corresponding to any of the components has become 0 or less. If the value is 0 or less, the process proceeds to step S202. If not, the process proceeds to step S203.

  (Step S <b> 202) The supply instruction output unit 21 outputs an instruction to supply the parts whose number of on-site inventory is 0 or less in step S <b> 201 from the warehouse to the production site. Then, the process returns to step S101.

(Step S203) The supply quantity receiving unit 22 determines whether a supply quantity has been received. And when supply quantity is received, the supply quantity is handed over to the delivery quantity update part 19, and it progresses to step S204, and when that is not right, it progresses to step S110.
(Step S204) The outgoing quantity update unit 19 updates the outgoing quantity according to the received supply quantity. Then, the process returns to step S101.

  Next, the operation of the component supply management apparatus according to this embodiment will be described using a specific example. The operation until the on-site inventory quantity is calculated in the specific example in the present embodiment is the same as that in the specific example according to the first embodiment, and the description thereof is omitted.

  It is assumed that production on the production line A has progressed and the number of on-site inventory of the part 2-2 becomes zero. Then, this is detected by the supply instruction output unit 21 (step S201), and the supply instruction output unit 21 transmits an instruction to supply 100 parts 2-2 to the production line A to the distribution facility control device 3. To do. Then, the distribution facility control device 3 allocates 100 inventory items for the part 2-2. As a result, it is assumed that 100 parts 2-2 are supplied from the warehouse to the production line A. Then, the distribution facility control device 3 transmits the supply quantity “100” to the component supply management device 1 in association with the component code “component 2-2”. It is assumed that “Line A” for identifying the production line is also associated with the supply quantity.

  When the supply quantity receiving unit 22 receives the supply quantity, the supply quantity receiving unit 22 passes to the delivery quantity updating unit 19 that 100 parts 2-2 have been supplied to the production line A (step S203). Then, the outgoing quantity update unit 19 adds 100 to the outgoing quantity (step S204). As a result, the on-site inventory quantity calculation unit 14 detects that the delivery quantity has been updated, updates the on-site inventory quantity, and the supply information is as shown in FIG.

In this specific example, the supply instruction output unit 21 may indicate the number of parts instructing supply by the maximum value. For example, in the case where the planned number of products to be produced is determined, the number obtained by subtracting the outgoing quantity from the planned number may be included in the instruction. In this way, when the inventory is allocated, the inventory is allocated within the range of the number included in the instruction and the parts are supplied to the production site. As a result, provisions are made according to the stock storage status. Specifically, when 100 parts 1 are stored at a certain stock position and 200 parts are stored at another stock position, the supply instruction output unit 21 outputs a maximum of 150 parts 1. If the instruction is output, the work related to taking out the part 1 from the warehouse and re-storing it can be avoided by allocating the stock of 100 stored parts.
