Description

  The present invention relates to a parts inventory management method, a parts inventory management apparatus, and a parts inventory management program.

  Many parts are used in the production of products such as mobile phones and personal computers. Parts are stored as stock in parts warehouses etc. in the factory, and order processing is performed and replenished at an appropriate timing so that there is no shortage at the time of production.

  In addition, the parts have an expiration date (for example, three months after receipt of goods, etc.), and a plant person in charge must use the parts for production of a product before the expiration date. Parts are in principle used from those whose expiration date comes early. In addition, since the surface treatment etc. are performed in the process of a production, the parts used for production will not apply the expiration date on production.

  On the other hand, there is known a technology for ordering and stocking materials used in a semiconductor manufacturing line (see, for example, Patent Document 1).

Unexamined-Japanese-Patent No. 2002-215974

  In general, parts received and stored at the factory are disposed of if they are not used by the expiration date. Also, even with common parts that can be used repeatedly in multiple factories, there has been no effective mechanism for exchanging parts.

  As a result, parts that are expected to be disposed of in a production plan at one plant are not used even if there is demand at another plant, resulting in a loss of disposal.

  FIGS. 1A to 1C show examples of management in three factory A to factory C with respect to certain common parts. FIG. 1A shows an example of inventory management data in factory A, and an allowance quantity (plan value) which is the number of parts used is set on each date excluding a closed day. In addition, the existing stock quantity of parts for each expiration date and the planned receipt quantity of goods are set.

  In the illustrated example, when viewed from the 1st July to the 15th July, the inventory for which the 15th of July, which was 90 as of June 30, is due for use on July 15, is nine each day It is used and runs out on 14 July. Therefore, from July 15th, the stock on August 31st, when the expiration date comes soon, will be used.

  FIG. 1B shows an example of inventory management data in factory B, and since the earliest expiration date inventory is August 31, the inventory is used from July 1st, and from July 15 The next expiration date, September 15, will be used.

  FIG. 1C shows an example of inventory management data in Factory C. The inventory whose expiration date is July 15 is used, and 45 pieces are left as of July 15. The remaining 45 are subject to disposal because July 15 is the expiration date.

  In the same period that 45 stocks are considered to be disposed of at plant C, plant A still uses the inventory of August 31 ahead of its expiration date, and at plant B, August 31 and 9 The stock is used on the 15th of January, and waste is generated when looking at plant A to plant C as a whole.

  Then, the form of an indication aims at offer of the method which can use up the part which has an expiration date by an expiration date in one side.

In the form of disclosure, for parts having use dates, a first period of time in which the number of stocks for each use date of parts in multiple factories and the number of use plans for each date of parts are collected, and dates are divided into predetermined periods. By comparing the number of planned use of each factory in the first period with the number of stocks in the same factory with the last day of the first period as the usage date, Calculate the excess number of factories with excess inventory, assign parts from the excess number of factories with excess inventory to the number of factories with shortage of inventory, and output parts move instructions to the assignment source and destination factories The computer executes the processing to be done.

  The form of an indication can use up the part which has an expiration date by expiration date.

<Operation>
4 to 6 are flowcharts showing processing examples of the above embodiment, and FIG. 4 is a processing example of the parts inventory data collection / aggregation unit 31 of all factory parts inventory management section 3, and FIG. 5 and FIG. The example of processing of judgment / movement directions part 32 is shown. These processes are executed by a computer program. In addition, the process about one common component is shown, and when multiple common components exist, the same process will be performed with respect to each.

  In FIG. 4, when the parts inventory data collection / aggregation unit 31 starts processing, the parts inventory data D2 transmitted from each factory parts inventory management unit 1 is received / stored (step S101), and data from all factories are received. If not collected (No in step S102), the reception and storage of the part inventory data D2 (step S101) are repeated.

  7A to 7C are diagrams showing an example of data transmitted from each factory. FIG. 7A corresponds to the A factory, FIG. 7B corresponds to the B factory, and FIG. 7C corresponds to the C factory. The factory specific data and the part specific data are omitted.

  In this example, it is assumed that the period is divided into half months, and the movement of parts is determined for three periods immediately after the determination time. Therefore, each factory parts inventory control unit 1 uses the production schedule data for three periods from July 1 to July 15, July 16 to July 31, and August 1 to August 15. The data of the provision quantity (plan value) for each date and the data of the existing stock quantity before the start of the first period for each use date are transmitted to the all-factory parts stock management unit 3.

  Returning to FIG. 4, when parts inventory data collection / aggregation unit 31 collects data from all factories (Yes in step S102), it consolidates the reserve quantity for each date of each factory and the number of inventory for each use date. (Step S103). Next, the parts inventory data collection / aggregation unit 31 calculates, for the latest period, the number of excesses or shortages due to the inventory in the same factory whose end date is the end date of the period, and calculates the production requirement for the subsequent period Step S104).

  FIG. 8 is a diagram showing an example of the aggregation of the allocation quantity and the inventory, the calculation of the number of excess and deficiency for the latest period, and the calculation of the production requirement for the other periods. In FIG. 8, the data of the provision quantity (plan value) for each date for three periods from July 1 to July 15, July 16 to July 31, and August 1 to August 15 are shown. In addition to grouping by factory, inventory quantities before the start of the first period are summarized for each expiration date and for each factory. In addition, for the most recent period from July 1 to July 15, 1 day each from the stock quantity on June 30 of the inventory in each factory whose use deadline is July 15 which is the last day of the period Calculate the excess / deficiency number by subtracting the reserve quantity. For the period from July 16 to July 31, and from August 1 to August 15, the excess and deficiency numbers are not calculated, and the production requirement, which is the total of the allocated quantities within the period, is calculate.

  Returning to FIG. 4, the parts inventory data collection / aggregation unit 31 extracts the unfilled portion of each plant for the latest period, and identifies the unfilled day (step S105). Next, the parts inventory data collection / aggregation unit 31 prioritizes each of the unfilled portions (step S106), and performs sorting in the order of priority (step S107). Sorting is intended to facilitate reference from the extracted data string, and may be omitted when referring to data by referring to the priority order first.

FIG. 9 is a diagram showing an example in which unfilled days for each factory are identified, prioritized, and sorted. In FIG. 9, the number of surplus and deficiency on the last day of the period is extracted from among the surplus and deficiency quantities on July 15 of FIG. 8 that are negative (black triangle symbol). The unfilled day is extracted from the day when it first became negative from July 1 to July 15. Priorities are for unfunded
・ Prioritize the day when the uncompleted day is earlier ・ Determine the one with the larger number of excess and deficiency of the last day of the term according to the priority criteria, and prioritize the unfilled day. In the example shown in the figure, the priority for the B plant is 1 and the priority for the A plant is 2.

  Returning to FIG. 4, the parts inventory data collection / aggregation unit 31 extracts the surplus of each plant for the latest period (step S108). Next, the parts inventory data collection / aggregation unit 31 prioritizes each surplus (step S109), and sorts in order of priority (step S110). Sorting is intended to facilitate reference from the extracted data string, and may be omitted when referring to data by referring to the priority order first.

FIG. 10 is a diagram showing an example of prioritizing and sorting the surplus of each factory. In FIG. 10, the surplus number on the last day of the period is extracted from among the surplus and deficiency quantities on July 15 of FIG. Priority is given to surplus
・ Prioritize one with a large number of surplus on the last day of the period ・ Prior to judge one with a large number of existing stocks in preference to the number of surplus. In the example shown in the figure, since only the C plant corresponds, the C plant has priority 1.

  Next, in FIG. 5, the component movement determination / movement instruction unit 32 initializes period numbers x and y used for control of processing to 1 (step S111). The period number x indicates a period during which the movement is determined, and the period number y indicates the expiration date of the inventory to which the last day of the period is appropriated. In the following description, the period indicated by the period number x will be simply referred to as the period x. Similarly, the expiration date of the last day of the period indicated by the period number y is also referred to as the expiration date y.

  FIG. 11 is a diagram showing an example of the period number, and in this example, the latest 1st July to 15th July is 1, 1st July 16th to 31st July 2nd, and 1st August to 28th August. The 15th is March 16, and the 16th to August 31th is 4, and the 1st of September to the 15th of September is 5.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether the period x has exceeded the target period (step S112). When the target period of judgment is 3 periods, it is determined that the target period is exceeded when x becomes 4. The range of the judgment target period is determined by the lead time from the aggregation of data to the determination of the allocation of parts inventory and the lead time from the part ordering to the goods receipt. In this example, one period (within 15 days) from when the data is consolidated in the parts inventory data collection / aggregation unit 31 to when the allocation of the parts inventory is decided, two periods from when the parts are ordered to when it is delivered ( Assuming that it takes 1 month, 3 periods are considered as the target period of judgment.

  Since the initial time is x = 1 and y = 1, and the target period is not exceeded (No in step S112), the parts movement determination / movement instruction unit 32 determines the surplus for the term of use y with respect to the unfilled portion of period x. Are allocated (allocated) in accordance with the priority order of the two, and at the same time, movement data (the move source plant, the move destination plant, the expiration date, the quantity, the transfer deadline, etc.) are held and the inventory number is adjusted (step S113).

  FIG. 12 is a diagram showing an example of the allocation of surplus components to the uncompleted part, which is an example of the first period (July 1 to July 15). In FIG. 12, according to the unsorted sorting result (FIG. 9), there are 110 unfilled portions of the B plant and 9 unfilled portions of the A plant. On the other hand, according to the sorting result of surplus (FIG. 10), there are 45 surpluses of which the expiration date of the C plant is July 15th. Therefore, the parts movement determination / movement instruction unit 32 assigns 45 pieces of the C plant to a part of 110 pieces of the B plant. At this stage, the application has not been completed because only a part has been applied.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the period x has been completed (step S114). In the present example, it is determined that the allocation can not be completed (No in step S114).

  Then, the parts movement determination / movement instruction unit 32 calculates the unfilled quantity (step S115). In the example of FIG. 12, since only 45 plants at plant C were allocated to 110 plants at plant B and nine plants at plant A, the unallocated quantity would be 74 (= 110 + 9-45). .

  Returning to FIG. 5, the part movement determination / movement instruction unit 32 determines whether there is stock (step S116). In the example of FIG. 12, the use deadline of plant C is 100 pieces on August 15, the expiration date of plant A is 200 pieces on August 31, and the use deadline of plant B is August 31 from the earliest side. There are 100 pieces of B, and 100 pieces of B plant expiration date on September 15. Therefore, in FIG. 5, the part movement determination / movement instruction unit 32 determines that there is an inventory (Yes in step S116).

  Then, the parts movement determination / movement instruction unit 32 sets y = y + 1 or the latest period number with inventory to y (step S117), and repeats the processing from the allocation process (step S113).

  In the example shown in Fig. 12, for the 74 unfunded cases, the expiration date for plant C is 100 to 74 for August 15 (the allocation is completed) and the expiration date for plant C is August 15 Reduce to 26 pieces.

  Referring back to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the allocation has been completed for the period x (step S114), but determines that the allocation is completed (Yes in step S114) in this example. Therefore, the component movement determination / movement instruction unit 32 increments the period number x (step S118), and returns to the determination of exceeding the target period (step S112). In the present example, since x = 2, it is determined that the target period is not exceeded (No in step S112), and the component movement determination / movement instruction unit 32 performs allocation for the second period (step S113).

  FIG. 13 is a diagram showing an example of the allocation of surplus components to the uncompleted part, which is an example of the second period (July 16th to July 31st). Since the number of excess and deficiency is not calculated in advance after the second period, it is prioritized and treated in descending order of the number of production requirements on the last day of the target period. In FIG. 13, there are 120 unfilled minutes of the B plant, 108 unfilled minutes of the A plant, and 60 unfilled minutes of the C plant in descending order of priority. On the other hand, there are 26 surplus items with the expiration date of August 15 at plant C. Therefore, the parts movement determination / movement instruction unit 32 allocates 26 pieces of the C plant to 120 parts of the B plant. Allotment has not been completed at this stage.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the period x has been completed (step S114). In the present example, it is determined that the allocation can not be completed (No in step S114).

  Then, the parts movement determination / movement instruction unit 32 calculates the unfilled quantity (step S115). In the example shown in FIG. 13, 26 units in plant C are only used for 120 units in plant B, 108 units in plant A and 60 units in plant C, so the unallocated quantity is 262 (= 120 + 108 + 60-26).

  Returning to FIG. 5, the part movement determination / movement instruction unit 32 determines whether there is stock (step S116). In the example shown in FIG. 13, 200 pieces of plant A have an expiration date of August 31, 200 pieces of plant B have 100 pieces of use expiration date of August 31, and 100 pieces of plant B have a limit of use of September 15 Exists. Therefore, in FIG. 5, the part movement determination / movement instruction unit 32 determines that there is an inventory (Yes in step S116).

  Then, the parts movement determination / movement instruction unit 32 sets y = y + 1 or the latest period number with inventory to y (step S117), and repeats the processing from the allocation process (step S113).

  In the example shown in FIG. 13, for the uncompleted 262 units, the use period of the A plant is 200 from August 31 and the use period of the B plant is 100 to 262 from August 31 (allocation complete) And the expiration date of B plant reduces the stock on August 31 to 38 pieces.

  Referring back to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the allocation has been completed for the period x (step S114), but determines that the allocation is completed (Yes in step S114) in this example. Therefore, the component movement determination / movement instruction unit 32 increments the period number x (step S118), and returns to the determination of exceeding the target period (step S112). In the present example, since x = 3, it is determined that the target period is not exceeded (No in step S112), and the component movement determination / movement instruction unit 32 performs allocation for the third period (step S113).

  FIG. 14 is a diagram showing an example of the allocation of surplus components to unfilled portions, and is an example of the third period (August 1 to August 15). Since the number of excess and deficiency is not calculated in advance after the second period, it is prioritized and treated in descending order of the number of production requirements on the last day of the target period. In FIG. 14, there are 110 unfilled minutes of plant B, 99 unfilled minutes of plant A, and 55 unfilled minutes of plant C in descending order of priority. On the other hand, there are 38 surplus items with the expiration date of August 31 at plant B. Therefore, the parts movement determination / movement instruction unit 32 assigns 38 pieces of B plant to 110 parts of B plant. Allotment has not been completed at this stage.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the period x has been completed (step S114). In the present example, it is determined that the allocation can not be completed (No in step S114).

  Then, the parts movement determination / movement instruction unit 32 calculates the unfilled quantity (step S115). In the example of FIG. 14, only 38 units of plant B were allocated to 110 units of plant B, 99 units of plant A and 55 units of plant C, so the unallocated quantity is 226 (= 110 + 99 + 55-38).

  Next, the parts movement determination / movement instruction unit 32 determines whether there is stock (step S116). In the example of FIG. 14, there are still 100 pieces of plant B whose expiration date is September 15. Therefore, in FIG. 5, the part movement determination / movement instruction unit 32 determines that there is an inventory (Yes in step S116).

  Then, the parts movement determination / movement instruction unit 32 sets y = y + 1 or the latest period number with inventory to y (step S117), and repeats the processing from the allocation process (step S113).

  In the example of FIG. 14, although the expiration date of the B plant is 100 from September 15 for 226 unfilled, the allocation is not completed.

  Returning to FIG. 5, the part movement determination / movement instruction unit 32 determines whether or not the allocation can be completed in the period x (step S114), but determines that the allocation can not be completed (No in step S114) in the present example.

  Then, the parts movement determination / movement instruction unit 32 calculates the unfilled quantity (step S115). In the example of FIG. 14, since only 100 plants in plant B are allocated to 226 unfilled, the unfilled quantity is 126 (= 226-100).

  Next, the parts movement determination / movement instruction unit 32 determines whether there is stock (step S116). In the example of FIG. 14, there is no longer stock. Therefore, in FIG. 5, the part movement determination / movement instruction unit 32 determines that there is no stock (No in step S116).

  Then, the parts movement determination / movement instruction unit 32 creates the parts movement instruction data D3 based on the movement data indicating the contents of the application from the start of the process, and transmits the part movement instruction data D3 to the corresponding factory parts inventory management unit 1 (step S119). . At the same time, if there is a shortage of stock and can not be fulfilled, order processing is also started and a new order is placed.

  Moreover, although it did not appear in an example, when period x exceeds an object period (Yes of step S112), it transfers to transmission of components movement data (step S119).

  Next, in FIG. 6, the parts movement determination / movement instruction unit 32 receives and stores the response from each of the factory parts inventory management unit 1 that has transmitted the parts movement data (step S120), and receives a response from the target factory. If not (No in step S121), reception and storage of the response (step S120) are repeated. The response includes the consent to the move instruction and the non-consent. If you do not agree, you may be accompanied by a reason.

  Next, the parts movement determination / movement instruction unit 32 determines whether consent has been received from all the target plants (step S122).

  If the consent has been received from all the factories (Yes in step S122), the parts movement determination / movement instruction unit 32 transmits the confirmation of the movement instruction to each factory parts stock management unit 1 to be moved (step S123). In response to this, each factory arranges for the actual movement, and sends a result report to all factory parts inventory control unit 3. The all factory parts inventory management unit 3 receives and stores the result after movement from each factory parts inventory management unit 1 (step S124), and corrects the process.

  Further, when receiving not agreeing even from the target one factory (No in step S122), the parts movement determination / movement instruction unit 32 corrects the data because the movement consistency can not be maintained (step S125). ), Redo the process from the beginning of FIG. Data modifications include deletion of the factory's reserve quantity and stock that do not agree, deletion of the excess and deficiency due to them and production requirements.
