Description

  The present technology relates to inventory management technology.

  When a failure occurs in a delivered device such as a computer, the customer calls a repair call center to request a repair. At this time, the call center requests a repair engineer (CE: Customer Engineer) to make a business trip to the customer and also requests the parts center to issue a replacement part according to the failure status estimated based on the information from the customer. This replacement part may be one type or multiple types of parts, and may be actually replaced with a faulty part, or may be returned to the parts center nearest to the CE office without being used. In some cases. When general inventory management is performed in a parts center, there is a case where excess inventory is held due to parts returned without being used.

  There are various technologies for predicting the number of stocks to optimize the number of stocks, but it is not sufficient for managing parts stock for replacement parts that are issued according to the failure status. .

  For example, there is a technology that optimally maintains the inventory of rental products. In this technology, a future inventory planned amount calculation means for obtaining a future inventory planned amount from the scheduled lending amount and the scheduled return amount, and a shortage occurrence corresponding to the frequency of the missing item is calculated from the obtained estimated inventory amount and a given missing component occurrence frequency. Calculation means for obtaining the future product inventory surplus / deficiency within the allowable range, and order processing means for obtaining and instructing the purchase amount and purchase time of the shortage product when the product shortage is predicted from this excess / deficiency amount is described Yes. However, in the case of such rental products, the reason for leaving is only general lending from the rental store, and there is almost no relationship between the reason for leaving and the return.

  Therefore, an object of the present technology is to provide a technology for appropriately managing inventory even in a case where the return mode of parts differs depending on the reason for leaving.

  In the information processing method according to the present technology, (A) the part return rate or the part usage rate for each delivery reason related to the part is stored for each part, and the part for each delivery reason related to the part for each part A process of reading out the part return rate or part usage rate and the number of parts issued for each delivery reason for a specific part from the data storage unit in which the number of goods issued is stored, and (B) the part return for each read out reason Correction processing for correcting the number of replenishments of a specific product or the number of stocks of a specific product based on the ratio or the sum of products of (1-part usage rate) and the number of parts issued.

  Even in the case where the return mode of parts varies depending on the reason of delivery, inventory management can be appropriately performed.

[Embodiment 1]
A system configuration example according to the first embodiment of the present technology is shown in FIG.

  A call center system 3 and an inventory management system 5 are connected to a network 1 such as the Internet or an in-house LAN (Local Area Network). The call center system 3 is further connected to a terminal device 7 (such as 7a and 7b in FIG. 1) used by an operator via a network 13 such as an in-house LAN. There is no limit to the number of terminal devices 7. The inventory management system 5 is also connected to a terminal device 9 (9a and 9b in FIG. 1) via a network 15 such as an in-house LAN. There is no limit to the number of terminal devices 9.

  The call center system 3 includes a delivery request unit 31 and a component data storage unit 33 as parts related to the present embodiment. For example, when an operator hears an error message for specifying the cause of a failure from a customer who has requested repair because a failure has occurred in a computer or the like and inputs the error message to the terminal device 7a, the terminal device 7a The data of the error message is output to the exit request unit 31. The unloading request unit 31 specifies a pair of a component identifier (for example, a number) and a unloading reason code corresponding to the received error message data and used for repair from the component data storage unit 33, and outputs the pair to the terminal device 7a. . Then, when a delivery instruction is given by an operator's instruction, the delivery request unit 31 outputs a delivery request including one or more pairs of a delivery reason code and a part identifier to the inventory management system 5. The delivery request includes data such as the identifier of the repair request and the CE in charge. When there are a plurality of parts centers, the delivery request includes the identifier of the parts center in charge.

  The component data storage unit 33 stores data as shown in FIG. 2, for example. In the example of FIG. 2, a part name, a part number that is an identifier of a part, a shipping reason code for each part, and one or a plurality of error messages for each shipping reason code are registered. The shipping reason code is set for each error message combination. In the present embodiment, the exit reason code is a code that represents the reason for the failure in combination with the part number, but may be a unique code for all parts. In this embodiment, an example of a component-based data structure is shown, but in this embodiment, data that outputs one or a plurality of pairs of a corresponding part number and a shipping reason code by a combination of error messages. It may be a structure.

  The inventory management system 5 includes an inventory management unit 51, an outgoing data storage unit 52, an inventory DB (database) 53, a processing unit 54, a data storage unit 55, an ordering data storage unit 56, and a log data storage unit 57. And an update unit 58. The inventory management unit 51 receives a delivery request including one or more pairs of a part number and a delivery reason code from the delivery request unit 31 of the call center system 3, and updates the delivery data storage unit 52 and the inventory DB 53 based on the received data. To do. Further, when the update process is performed, the inventory management unit 51 stores the update log in the log data storage unit 57. Furthermore, the inventory management unit 51 also outputs an instruction to the worker who actually performs the work of delivering the parts from the data included in the delivery request.

  Further, after the repair at the customer is completed, upon receiving a repair completion notification including data of used parts and unused parts among the delivered parts from the terminal device 9a or the like, the inventory management unit 51 stores the inventory. The DB 53 and the outgoing data storage unit 52 are updated. The repair completion notification includes, for example, a repair request identifier, one or more pairs of the identifier of the part that has been issued and the issue reason code of the part, and one of the identifier of the return part and the issue reason code of the return part. Or a plurality of pairs are included. In response to such data, the inventory management unit 51 stores the update log in the log data storage unit 57.

  The inventory DB 53 stores data as shown in FIG. 3, for example. In the example of FIG. 3, the part name, the part number, and the current actual stock quantity are registered for each part center. When a part is issued, the actual stock quantity is reduced accordingly, and when a part is returned unused, the actual stock quantity is increased accordingly. Further, if parts are replenished, the actual stock quantity increases accordingly.

  Further, the outgoing data storage unit 52 stores data as shown in FIG. 4, for example. In the example of FIG. 4, a part name, a part number, a shipping reason code and a number of outgoings for each part are registered. The outgoing data storage unit 52 holds data for which a repair completion notification has not been received. That is, when a delivery request is received, the number of outgoings for a pair of a part identifier and a delivery reason code included in the outgoing request is increased. In addition, when the repair completion notification is received, the number of outgoings for the pair of the return part identifier and the return reason code included in the repair completion notice is reduced.

  The processing unit 54 uses the data stored in the outgoing data storage unit 52, the inventory DB 53, and the data storage unit 55 to perform processing for ordering parts.

  For example, data as shown in FIG. 5 and data as shown in FIG. 6 are stored in the data storage unit 55. FIG. 5 shows an example of the reference value table. In the example of FIG. 5, for each part center, a part name, a part number, a maximum reference value for the inventory quantity, and a minimum reference value for the inventory quantity are registered. In the present embodiment, when the value falls below the minimum reference value, it is set in advance for each part in order to increase the stock so that the maximum reference value is reached.

  FIG. 6 shows an example of the return rate table. In the example of FIG. 6, a part name, a part number, a shipping reason code for each part, and a return rate for each combination of the part and the shipping reason code are registered. The return rate is the return rate of parts that can be used again. However, the usage rate may be registered. That is, (1-return rate) = usage rate. The exit reason code and the part identifier (number) are the same as those stored in the part data storage unit 33.

  In addition, from the data accumulated in the log data storage unit 57, the update unit 58 recalculates the return rate for each combination of the part and the shipping reason code, and the return rate table stored in the data storage unit 55 The data may be updated. However, since such processing may be performed by other means without providing the update unit 58, it is indicated by a dotted line block in FIG.

  Next, processing contents of the processing unit 54 will be described with reference to FIGS. 7 and 8. The following processing is performed in units of parts centers, for example, at a predetermined timing (for example, once a day).

  The processing unit 54 identifies one unprocessed part among the parts registered in the inventory DB 53 (step S1). Further, the processing unit 54 reads out the current actual stock quantity of the specified component from the inventory DB 53, and reads out the minimum reference value of the specified component from the reference value table of the data storage unit 55 (step S3).

  The processing unit 54 determines whether the current actual stock quantity is larger than the minimum reference value (step S5). In the present embodiment, when the current actual stock quantity is larger than the minimum reference value, stock replenishment is not performed, and therefore the process proceeds to step S21 in FIG.

  On the other hand, when the current actual stock quantity is less than or equal to the minimum reference value, the processing unit 54 reads the maximum reference value of the specified part from the reference value table of the data storage unit 55 (step S7). Further, the processing unit 54 calculates the provisional replenishment number by the maximum reference value−the current actual inventory number (step S9). Then, the processing unit 54 determines whether the provisional replenishment number exceeds 0 (step S11). If the provisional replenishment number is 0 or less, the replenishment is not performed, and the process proceeds to step S21 in FIG.

On the other hand, when the provisional replenishment number exceeds 0, the processing unit 54 reads out the number of outgoings for each outgoing event code for the specified part from the outgoing data storage unit 52, and returns the rate rate table of the data storage unit 55. From the above, the return rate for each delivery reason code is read for the specified part (step S13). Thereafter, the processing unit 54 calculates the replenishment number by the provisional replenishment number−Σshipping _{reason code} shipping number × return rate (step S15). In other words, the sum of the results of obtaining the product of the number of issues and the return rate for each issue reason code is subtracted from the provisional replenishment number. The sum of products of the number of issues and the return rate for each issue reason code represents the number of parts that are assumed (expected) to be returned, that is, the expected number of returned parts. Since the assumed number of parts to be returned is a potential inventory quantity, an assumed inventory quantity (that is, an assumed inventory quantity) can be obtained by adding to the current actual inventory quantity. Specifically, the number of provisional replenishment is: replenishment number = maximum reference value−current actual inventory number−assumed return part number = maximum reference value− (current actual inventory number + assumed return part number) = maximum reference value−assumed inventory. Transformed with numbers. Furthermore, since the provisional replenishment number is the replenishment number according to the conventional method, it can be said that the replenishment number according to the present embodiment is calculated after correcting the replenishment number according to the conventional method based on the number of assumed return parts. The processing shifts to the processing in FIG.

  Shifting to the description of the processing in FIG. 8, the processing unit 54 determines whether the replenishment number is greater than 0 (step S <b> 17). If the replenishment number is 0 or less, no replenishment is performed, and the process proceeds to step S21. On the other hand, when the replenishment number is larger than 0, the processing unit 54 stores data for placing an order for the specified parts by the replenishment number in the order data storage unit 56 (step S19). In the present embodiment, order data including the part identifier and the number of replenishments is stored in the order data storage unit 56. This data is later transferred to a purchasing system, for example.

  Thereafter, the processing unit 54 determines whether there is an unprocessed part among the parts registered in the inventory DB 53 (step S21). If there is an unprocessed part, the process returns to step S1 in FIG. On the other hand, if there is no unprocessed part, the process ends.

  As described above, excess inventory can be suppressed by calculating the number of replenishments assuming that there is as much inventory as the number of expected return parts. By optimizing the number of stocks, in addition to logistics costs (transportation costs, packing costs, labor costs, etc.), storage space can be reduced.

[Embodiment 2]
It is also possible to calculate the number of replenishments with a processing flow different from that of the first embodiment. For example, a processing flow as shown in FIG. 9 may be used.

  The following processing is also performed in units of parts centers, for example, at a predetermined timing (for example, once a day).

  First, the processing unit 54 identifies one unprocessed part among the parts registered in the inventory DB 53 (step S31). In addition, the processing unit 54 reads the current actual inventory number of the specified part from the inventory DB 53, and reads the minimum reference value of the specified part from the reference value table of the data storage unit 55 (step S33).

  The processing unit 54 determines whether or not the current actual stock quantity is larger than the minimum reference value (step S35). In the present embodiment, when the current actual stock quantity is larger than the minimum reference value, stock replenishment is not performed, and therefore the process proceeds to step S45.

On the other hand, when the current actual stock quantity is less than or equal to the minimum reference value, the processing unit 54 reads the maximum reference value of the identified part from the reference value table of the data storage unit 55 and returns the data storage unit 55 From the rate table, the return rate for each delivery reason code is read for the specified part, and the number of outputs for each delivery reason code for the specified part is read from the delivery data storage unit 52 (step S37). In addition, the processing unit 54 calculates the number of replenishments based on the highest reference value−the current actual stock quantity−Σthe _{outgoing event code} outgoing number × the return rate (step S39).

  Then, the processing unit 54 determines whether or not the replenishment number exceeds 0 (step S41). If the replenishment number is 0 or less, no replenishment is performed, and the process proceeds to step S45.

  On the other hand, when the replenishment number exceeds 0, the processing unit 54 stores data for ordering the specified parts by the replenishment number in the order data storage unit 56 (step S43). In the present embodiment, order data including the part identifier and the number of replenishments is stored in the order data storage unit 56. This data is later transferred to a purchasing system, for example.

  Thereafter, the processing unit 54 determines whether there is an unprocessed part among the parts registered in the inventory DB 53 (step S45). If there is an unprocessed part, the process returns to step S31. On the other hand, if there is no unprocessed part, the process ends.

  As described above, the replenishment number similar to that of the first embodiment is calculated without calculating the provisional replenishment number, and the stock quantity is optimized.

[Embodiment 3]
Furthermore, the processing flow can be modified. An example is shown in FIG.

  First, the processing unit 54 identifies one unprocessed part among the parts registered in the inventory DB 53 (step S51). In addition, the processing unit 54 reads the current actual stock quantity of the identified part from the inventory DB 53, reads the return rate for each delivery reason code for the identified part from the return rate table of the data storage unit 55, and outputs the delivery data. From the storage unit 52, the number of outgoings for each outgoing reason code is read for the specified part (step S53).

Then, the processing unit 54 calculates the estimated inventory quantity by the current actual inventory quantity + _{Σexcavation reason code} delivery quantity × return rate (step S55). The estimated inventory quantity can be obtained by correcting the current actual inventory quantity by the number of Σ _{delivery reason codes} issued x return rate = assumed number of returned parts. By using the assumed stock quantity, it becomes possible to prevent the stock from being excessively held.

  Further, the processing unit 54 reads out the minimum reference value of the identified component from the reference value table of the data storage unit 55 (Step S57). Then, the processing unit 54 determines whether or not the assumed stock quantity is equal to or greater than the minimum reference value (step S59). If the estimated inventory quantity is equal to or greater than the minimum reference value, the inventory is not replenished, and the process proceeds to step S65.

  On the other hand, if the estimated inventory quantity is less than the minimum reference value, the processing unit 54 reads the maximum reference value of the identified component from the reference value table of the data storage unit 55 (step S60). Then, the processing unit 54 calculates the replenishment number by the maximum reference value−the assumed inventory number (step S61). Then, the processing unit 54 stores, in the order data storage unit 56, data for ordering the specified parts by the number of replenishments (step S63). In the present embodiment, order data including the part identifier and the number of replenishments is stored in the order data storage unit 56. This data is later transferred to the purchasing system.

  Thereafter, the processing unit 54 determines whether there is an unprocessed part among the parts registered in the inventory DB 53 (step S65). If there is an unprocessed part, the process returns to step S51. On the other hand, if there is no unprocessed part, the process ends.

  The replenishment number is calculated based on the assumed inventory number, the replenishment number similar to that of the first embodiment is calculated, and the inventory number is optimized.

  Although the embodiment of the present technology has been described above, the present technology is not limited to this. For example, the system configuration diagram shown in FIG. 1 is an example, and may not necessarily match the actual program module configuration. Similarly, the configuration of the data storage unit may not match the actual file configuration. The data storage unit and the DB may be combined into one, or may be divided into a larger number of storage units, but this is an implementation problem.

  Further, the processing flow can be variously changed as long as the processing result does not change, and the order of the steps may be changed or the steps may be executed in parallel. Further, the system may be implemented by one or a plurality of computers (that is, information processing apparatuses).

  Further, in the example described above, the case where the processing flow is executed at a predetermined timing has been shown. However, for example, a predetermined condition (for example, when the stock quantity becomes less than the minimum reference value) for individual parts is set. If it is satisfied, the number of replenishments may be calculated.

  Note that the call center system 3 and the inventory management system 5 described above are computer devices, and as shown in FIG. 11, a memory 2501, a CPU (Central Processing Unit) 2503, and a hard disk drive (HDD). A bus 2519 connects a display control unit 2507 connected to 2505, a display device 2509, a drive device 2513 for the removable disk 2511, an input device 2515, and a communication control unit 2517 for connecting to a network. An operating system (OS: Operating System) and an application program for executing the processing in this embodiment are stored in the HDD 2505, and are read from the HDD 2505 to the memory 2501 when executed by the CPU 2503. The CPU 2503 controls the display control unit 2507, the communication control unit 2517, and the drive device 2513 according to the processing content of the application program, and performs a predetermined operation. Further, data in the middle of processing is mainly stored in the memory 2501, but may be stored in the HDD 2505. In an embodiment of the present technology, an application program for performing the above-described processing is stored in a computer-readable removable disk 2511 and distributed, and installed from the drive device 2513 to the HDD 2505. In some cases, the HDD 2505 may be installed via a network such as the Internet and the communication control unit 2517. Such a computer apparatus realizes various functions as described above by organically cooperating hardware such as the CPU 2503 and the memory 2501 described above and programs such as the OS and application programs. .

  The above-described embodiment can be summarized as follows.

  In the information processing method according to the present embodiment, (A) the part return rate or the part usage rate for each delivery reason related to the part is stored for each part, and each delivery reason related to the part for each part. A process of reading out the part return rate or part usage rate and the number of parts issued for each specific reason from the data storage unit storing the number of parts issued, and (B) for each read reason And correction processing for correcting the replenishment number of the specific product or the inventory number of the specific product based on the sum of the product of the part return rate or (1-part usage rate) and the number of parts issued.

  In this way, it is possible to avoid unnecessary stock replenishment by the sum of the product of the part return rate or (1-part usage rate) and the number of parts issued for each delivery reason. As a result, the cost can be reduced.

  Note that the data storage unit described above may further store the current actual inventory number and the first reference value for inventory for each component. In this case, the correction process described above calculates the first value obtained by subtracting the sum of the current stock quantity stored in the data storage unit and the above sum from the first reference value stored in the data storage unit. You may make it include the process to calculate. In this way, a first value representing an appropriate number of replenishments can be obtained.

  Further, in the information processing method, when the first value described above is a positive integer, a process of placing an order for a specific part may be performed.

  Further, the data storage unit described above may further store the current actual stock quantity for each part. In this case, the correction process described above may include a process of calculating a second value obtained by adding the current actual inventory number stored in the data storage unit and the total sum. In this way, it is possible to grasp the realistic prospective inventory quantity.

  Furthermore, the data storage unit described above may further store a second reference value for inventory for each component. In this case, if the second value is less than the second reference value stored in the data storage unit, a process of placing an order for a specific part may be further included. The replenishment of parts can be suppressed, and the number of stocks is optimized.

  The data storage unit described above may further store a second reference value that is smaller than the first reference value for each component. In such a case, when the actual stock quantity currently stored in the data storage unit is lower than the second reference value stored in the data storage unit, the correction process described above is performed. Also good.

  It is possible to create a program for causing a computer to carry out the processing described above, such as a flexible disk, an optical disk such as a CD-ROM, a magneto-optical disk, and a semiconductor memory (for example, ROM). Or a computer-readable storage medium such as a hard disk or a storage device.
