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 inventory in a parts warehouse or the like in the factory, and are ordered and replenished at an appropriate timing so as not to run out during production.

  In addition, an expiration date (for example, 3 months from warehousing) is set for the part, and the person in charge of the factory must use the part for production of the product before the expiration date. In principle, parts are used from the one whose expiry date comes early. Since the parts used for production are subjected to surface treatment in the course of production, the expiration date for production is not applicable.

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

JP 2002-215974 A

  Generally, parts received and stored in a factory are disposed of when they are not used by the expiration date. In addition, even for common parts that can be reused in multiple factories, there is no effective mechanism for accommodating parts.

  For this reason, parts that are expected to be disposed of from a production plan in one factory are not utilized even when there is demand in other factories, resulting in a loss of disposal.

  1A to 1C show an example of management in three A factories to C factories for a common part. FIG. 1A shows an example of inventory management data in factory A, and an allocation quantity (planned value), which is the number of parts used, is set on each date excluding closed days. In addition, the existing stock quantity of parts and the scheduled receipt quantity for each expiration date are set.

  In the example shown in the figure, in the half-month period from July 1st to July 15th, the inventory expired on July 15th, which was 90 as of June 30th, is 9 each day. Used and will be used up on July 14th. Therefore, from July 15th, the stock on August 31 when the expiration date comes next will be used.

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

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

  In the same period as the inventory of 45 pieces at the factory C is disposed of, the factory A is still using the August 31 inventory that has expired, and the factory B is August 31 and 9 The inventory on the 15th of the month is used, and waste is generated when the factories A to C are viewed as a whole.

  In view of the above, an object of one aspect of the disclosure is to provide a technique capable of using up a part having an expiration date before the expiration date.

  The form of disclosure collects the number of inventory for each part expiration date and the number of usage plans for each part date in parts of multiple factories, and uses the expiration date in order from the number of usage plans with earlier dates. The computer executes a process of sequentially assigning parts from the stock quantity with the earliest stock and outputting a part movement instruction to the assigning factory and the assigning factory.

  In the disclosed form, a part having an expiration date can be used up by the expiration date.

  Note that the factories A to C are not limited to those belonging to one company, but may include those belonging to different companies if an agreement is formed to allow interchange of common parts.

  Each factory parts inventory management unit 1, delivery instruction unit 2, and all factory parts inventory management unit 3 have a hardware configuration of a general computer device, and include a CPU (Central Processing Unit), ROM (Read Only). Memory (RAM), RAM (Random Access Memory), NVRAM (Non-Volatile Random Access Memory), an auxiliary storage device, a communication interface, and the like.

<Operation>
4 to 6 are flowcharts showing processing examples of the above embodiment, FIG. 4 is a processing example of the parts inventory data collection / aggregation unit 31 of the whole factory parts inventory management unit 3, and FIGS. The example of a process of the judgment / movement instruction | indication part 32 is shown. These processes are executed by a computer program. Note that the processing for one common component is shown, and when there are a plurality of common components, the same processing is performed for each.

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

  7A to 7C are diagrams showing examples of data transmitted from each factory. FIG. 7A corresponds to factory A, FIG. 7B corresponds to factory B, and FIG. 7C corresponds to factory C. Note that factory specific data and parts specific data are omitted.

  In this example, the period is divided in half-month units, and the movement of the component is determined for three periods immediately after the determination time point. Therefore, each factory parts inventory management part 1 is as production plan data about 3 periods from July 1 to July 15, July 16 to July 31, August 1 to August 15. The data of the allocated quantity (planned value) for each date and the data of the existing inventory quantity before the start of the first period for each expiration date are transmitted to all factory parts inventory management unit 3.

  Returning to FIG. 4, when collecting data from all factories (Yes in step S <b> 102), the parts inventory data collection / aggregation unit 31 aggregates the allocated quantity for each factory date and the inventory quantity for each expiration date. (Step S103). Next, the parts inventory data collection / aggregation unit 31 calculates the excess or deficiency due to the inventory in the same factory whose last day is the expiration date for the latest period, and calculates the production requirements for the subsequent period ( Step S104).

  FIG. 8 is a diagram showing an example of aggregation of the allocated quantity and inventory, calculation of the excess / deficiency number for the most recent period, and calculation of production requirements for other periods. In FIG. 8, for the three periods from July 1 to July 15, July 16 to July 31, and August 1 to August 15, the data of the allocation quantity (planned value) for each date is shown. Summarize each factory and collect the inventory quantity before the start of the first period for each expiration date and each factory. In addition, for the most recent period from July 1 to July 15, one day from the number of inventory on June 30 of the inventory in each factory whose expiration date is July 15 which is the last day of the period. The excess or deficiency is calculated by subtracting the allocated quantity. For the subsequent periods from July 16 to July 31, August 1 to August 15, the excess and deficiency numbers are not calculated, and the production requirement, which is the total of the allocated quantity within the period, is calculated for each factory. calculate.

  Returning to FIG. 4, the parts inventory data collection / aggregation unit 31 extracts the unappropriated portion of each factory for the most recent period, and specifies the date when it is unappropriated (step S105). Next, the parts inventory data collection / aggregation unit 31 assigns priorities to the unallocated portions (step S106), and sorts them in order of priority (step S107). The sort is for facilitating reference from the extracted data string, and may be omitted when referring to the data by referring to the priority order first.

FIG. 9 is a diagram showing an example in which unassigned days are identified, prioritized, and sorted with respect to unappropriated portions of each factory. In FIG. 9, the excess / deficiency number at the end of the period is extracted from the excess / deficiency quantity of July 15 in FIG. 8 that is minus (black triangle symbol). The unappropriated day is extracted from the first negative day from July 1 to July 15. If the priority is unappropriated,
・ Priority is given to those with earlier days that are unappropriated. ・ Priority is given to those with a larger excess or deficiency at the end of the period, and priority is given to those days that are not appropriate. In the example shown in the figure, the factory B is unappropriated earlier and the number of excess and deficiency at the end of the period is larger. Therefore, the priority is 1, and the factory A is 2.

  Returning to FIG. 4, the parts inventory data collection / aggregation unit 31 extracts the surplus of each factory for the most recent 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). The sort is for facilitating reference from the extracted data string, and may be omitted when referring to the data by referring to the priority order first.

FIG. 10 is a diagram showing an example in which priorities are assigned and sorted with respect to surplus portions in each factory. In FIG. 10, the surplus number at the end of the period is extracted from the excess and shortage quantities on July 15 in FIG. The priority is the surplus,
・ Prefer priority is given to the surplus at the end of the period. ・ Prefer priority is given to the surplus. In the example shown in the drawing, only the factory C is applicable, and therefore the factory C is given priority 1.

  Next, in FIG. 5, the component movement determination / movement instruction unit 32 initializes period numbers x and y used for process control to 1 (step S <b> 111). 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 be used on the last day of the period. In the following description, the period indicated by the period number x is also simply referred to as period x. Similarly, the expiration date on 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 examples of period numbers. In this example, the latest July 1 to July 15 is 1, July 16 to July 31 is 2, and August 1 to August. 15 is 3, August 16 to August 31 is 4, and September 1 to September 15 is 5.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the period x exceeds the target period (step S112). In the case where the target period of determination is three periods, it is determined that the target period has been exceeded when x becomes four. Note that the range of the target period of determination is determined by the lead time from when the data is aggregated until the allocation of the parts inventory is confirmed and the lead time from when the parts are ordered until the receipt. In this example, one period (within 15 days) from when the data is aggregated to the parts inventory data collection / aggregation unit 31 until the allocation of the parts inventory is confirmed, and two periods from when the parts are ordered to delivery ( Assuming that it takes 1 month), 3 periods are subject to judgment.

  Since x = 1 and y = 1 at the first time and the target period is not exceeded (No in step S112), the part movement determination / movement instruction unit 32 has an excess of the expiration date y with respect to the unallocated portion of the period x. Are allocated (assigned) according to the priority order of the two, and at the same time, the movement data (movement source factory, movement destination factory, expiration date, quantity, movement time limit, etc.) are retained and the number of inventory is adjusted (step S113).

  FIG. 12 is a diagram illustrating an example of appropriation from the surplus to the unappropriated portion, and is an example of the first period (July 1 to July 15). In FIG. 12, there are 110 unappropriated portions of factory B and 9 unappropriated portions of factory A in accordance with the unappropriated sorting result (FIG. 9). On the other hand, according to the sorting result of surplus (FIG. 10), there are 45 surpluses whose expiration date of C factory is July 15th. Therefore, the part movement determination / movement instruction unit 32 allocates 45 pieces of the C factory to a part of 110 pieces of the B factory. At this stage, the allocation has not been completed because only a portion has been allocated.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the allocation of the period x has been completed (step S <b> 114). In this example, it is determined that the allocation cannot be completed (No in step S114).

  Then, the part movement determination / movement instruction unit 32 calculates an unallocated quantity (step S115). In the example of FIG. 12, since only 45 of the C factory is allocated to 110 unallocated of the B factory and 9 of the A factory, the unallocated quantity is 74 (= 110 + 9−45). .

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether there is inventory (step S <b> 116). In the example of FIG. 12, the expiry date of the C factory is 100 on August 15th, the expiry date of the A factory is 200th on August 31, and the expiry date of the B factory is August 31st. There are 100 of them, and the expiry date of the factory B is 100 on September 15th. Therefore, in FIG. 5, the component movement determination / movement instruction unit 32 determines that there is a stock (Yes in step S116).

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

  In the example of FIG. 12, for 74 unappropriated items, the expiry date of C factory is appropriated from 100 pieces on August 15 to 74 pieces (approval completion), and the expiry date of C factory is August 15 stock. Is reduced to 26.

  Returning to FIG. 5, the part movement determination / movement instruction unit 32 determines whether or not the period x has been fully allocated (step S114), but in this example, determines that the allocation is complete (Yes in step S114). 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 this 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 applies the second period (step S113).

  FIG. 13 is a diagram showing an example of appropriation from the surplus to the unappropriated portion, and is an example for the second period (July 16 to July 31). Since the calculation of excess / deficiency numbers is not performed in advance after the second period, priorities are assigned in descending order of the number of production required on the last day of the target period. In FIG. 13, there are 120 unappropriated portions of the factory B, 108 unappropriated portions of the factory A, and 60 unappropriated portions of the factory C in descending order of priority. On the other hand, there are 26 surpluses for which the expiration date of the C factory is August 15th. Therefore, the part movement determination / movement instruction unit 32 assigns 26 pieces of the C factory to some 120 pieces of the B factory. At this stage, allocation has not been completed.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the allocation of the period x has been completed (step S <b> 114). In this example, it is determined that the allocation cannot be completed (No in step S114).

  Then, the part movement determination / movement instruction unit 32 calculates an unallocated quantity (step S115). In the example of FIG. 13, only the 26 units of C factory are allocated to 120 units of B factory, 108 units of A plant, and 60 units of C plant, so that the unapplied quantity is 262 (= 120 + 108 + 60−26).

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether there is inventory (step S <b> 116). In the example of FIG. 13, the expiration date of the A factory is 200 on August 31, 100, the expiration date of the B factory is 100 on August 31, and the expiration date of the B factory is 100 on September 15. Exists. Therefore, in FIG. 5, the component movement determination / movement instruction unit 32 determines that there is a stock (Yes in step S116).

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

  In the example of FIG. 13, for the 262 unappropriated, the expiration date for the A factory is 200 on August 31 and the expiration date for the B factory is 100 to 262 from August 31 (allocation complete). And the inventory of the factory B's expiration date on August 31 is reduced to 38 pieces.

  Returning to FIG. 5, the part movement determination / movement instruction unit 32 determines whether or not the period x has been fully allocated (step S114), but in this example, determines that the allocation is complete (Yes in step S114). 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 this 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 applies the third period (step S113).

  FIG. 14 is a diagram showing an example of appropriation from the surplus to the unappropriated portion, and is an example for the third period (August 1 to August 15). Since the calculation of excess / deficiency numbers is not performed in advance after the second period, priorities are assigned in descending order of the number of production required on the last day of the target period. In FIG. 14, there are 110 unappropriated portions of the factory B, 99 unappropriated portions of the factory A, and 55 unappropriated portions of the factory C in descending order of priority. On the other hand, there are 38 surpluses for which the expiration date of the factory B is August 31st. Therefore, the part movement determination / movement instruction unit 32 assigns 38 pieces of the B factory to a part of 110 pieces of the B factory. At this stage, allocation has not been completed.

  Returning to FIG. 5, the component movement determination / movement instruction unit 32 determines whether or not the allocation of the period x has been completed (step S <b> 114). In this example, it is determined that the allocation cannot be completed (No in step S114).

  Then, the part movement determination / movement instruction unit 32 calculates an unallocated quantity (step S115). In the example of FIG. 14, only the 38 units of B factory are allocated to 110 units of B factory, 99 units of A plant and 55 units of C plant, but the unapplied quantity is 226 (= 110 + 99 + 55−38).

  Next, the part movement determination / movement instruction unit 32 determines whether there is a stock (step S116). In the example of FIG. 14, there are still 100 expiration dates for September 15, factory B. Therefore, in FIG. 5, the component movement determination / movement instruction unit 32 determines that there is a stock (Yes in step S116).

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

  In the example of FIG. 14, 226 unappropriated items are allocated from 100 units on the 15th of September, but the allocation is not completed.

  Returning 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 S <b> 114), but determines that the allocation cannot be completed in this example (No in step S <b> 114).

  Then, the part movement determination / movement instruction unit 32 calculates an unallocated quantity (step S115). In the example of FIG. 14, only 100 of the factory B is allocated to 226 unallocated, so the unallocated quantity is 126 (= 226-100).

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

  Then, the part movement determination / movement instruction unit 32 creates the part movement instruction data D3 based on the movement data indicating the contents of appropriation from the start of processing, and transmits it to the corresponding factory part inventory management unit 1 (step S119). . At the same time, if it is not possible to allocate due to a shortage of inventory, the ordering process is activated and a new order is placed.

  Also, although not appearing in the example, when the period x exceeds the target period (Yes in step S112), the process shifts to transmission of part movement data (step S119).

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

  Next, the part movement determination / movement instruction unit 32 determines whether or not consent has been received from all target factories (step S122).

  When consent is received from all factories (Yes in step S122), the component movement determination / movement instruction unit 32 transmits confirmation of the movement instruction to each factory component inventory management unit 1 to be moved (step S123). In response to this, each factory arranges actual movement, and a result report is transmitted to all factory parts inventory management 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 processing.

  Further, when it is received from one of the target factories that it does not agree (No in step S122), the movement consistency is not maintained, so the component movement determination / movement instruction unit 32 corrects the data (step S125). ), The process from the beginning of FIG. Data corrections include the disposition of the factory's disapproved quantities and inventory, the deletion of excess and deficiency resulting from them and production requirements.
