[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0018] [1. Overview] First, an overview of the present invention will be described with reference to Fig. 1 to Fig. 3. Fig. 1 is a diagram showing an example of conventional status management. Fig. 2 is a diagram showing an example of status linking master in this embodiment. Fig. 3 is a diagram showing an example of status management in this embodiment.

[0019] Traditionally, in the electrical equipment industry and other industries, returned products were stored on shelves separate from regular inventory, but because there were many products handled, managing regular and returned inventory became complicated, and returned inventory often ended up remaining in inventory. In addition, traditionally, there was no function to automatically change the status, and since they had the same status, it was often difficult to distinguish between regular and returned products and to manage them properly. Traditionally, returned products were assessed by a supplier, and once the assessment was completed, they were classified as either to be discarded or to be shipped again.

[0020] Therefore, in this embodiment, when a product is returned, its status is differentiated from that of a normal product, control is applied to prevent it from being shipped, and retained inventory management is implemented to check whether the returned inventory is left behind, thereby providing a mechanism to improve the accuracy of returned inventory management.

[0021] For example, as shown in Figure 1, in the past, products were managed as normal, shippable items at all times: when sales were recorded, when they were returned, and after evaluation by the supplier.

[0022] Here, as shown in FIG. 2, in this embodiment, the status classification of the product is divided into three categories, A, B, and C (A: no control is applied on each input screen, B: a warning message can be issued when sales input and shipment input are performed, and C: a stop is applied when sales input and shipment input are performed), and the master is set. In this embodiment, a status can be added arbitrarily, and a status classification can be set for each. In this embodiment, a shipping check can be performed by the shipping category (0: shipping possible, 1: warning, 2: shipping impossible). In this embodiment, a status can be specified at the time of arrival or shipment. In addition, conventionally, defective products, which are products that are judged to be defective during inspection at the time of new arrival, or retained products, which are products that have missed the chance of production or shipment due to seasonal or cyclical fluctuations, were classified as status B (or C). That is, conventionally, if a product cannot be used as a single product, or a product that cannot be shipped at present but is functionally usable as a production part or service part, the status classification of these products was B (or C).

[0023] Therefore, as shown in Fig. 3, in this embodiment, the product status is managed separately at the time of recording sales, at the time of return, and after the supplier's appraisal, so that (1) when recording the return slip, the status is automatically changed to "waiting appraisal" and the inventory is recorded, (2) when the supplier's appraisal is completed and shipping is possible, the status is changed to "after appraisal" on the status change screen, and (3) it is possible to check from the inquiry screen how much of the returned inventory has been held up as inventory since it was recorded. As a result, in this embodiment, after the return, an appraisal request is made to the supplier, and shipping can be controlled until the appraisal is completed, and since the system allows the setting of whether shipping is possible for each status, shipping can be controlled by changing the status, and since inventory can be managed for each status, it is possible to grasp how many returned products there are.

[0024] [2. Configuration] An example of the configuration of the returned stock management device 100 according to this embodiment will be described with reference to Fig. 4. Fig. 4 is a block diagram showing an example of the configuration of the returned stock management device 100 according to this embodiment.

[0025] 4, the returned goods inventory management device 100 is a commercially available desktop personal computer. The returned goods inventory management device 100 is not limited to a stationary information processing device such as a desktop personal computer, but may be a portable information processing device such as a commercially available notebook personal computer, a PDA (Personal Digital Assistant), a smartphone, or a tablet personal computer.

[0026] The returned goods inventory management device 100 includes a control unit 102, a communication interface unit 104, a storage unit 106, and an input / output interface unit 108. The units included in the returned goods inventory management device 100 are connected to each other so as to be able to communicate with each other via any communication path.

[0027] The communication interface unit 104 communicably connects the returned inventory management device 100 to the network 300 via a communication device such as a router and a wired or wireless communication line such as a dedicated line. The communication interface unit 104 has a function of communicating data with other devices via the communication line. Here, the network 300 has a function of connecting the returned inventory management device 100 and the server 200 so that they can communicate with each other, and is, for example, the Internet or a LAN (Local Area Network).

[0028] An input device 112 and an output device 114 are connected to the input / output interface unit 108. The output device 114 may be a monitor (including a touch panel), a speaker, or a printer. The input device 112 may be a keyboard, a mouse, a microphone, or a monitor that cooperates with a mouse to realize a pointing device function. In the following, the output device 114 may be referred to as the monitor 114 or the printer 114, and the input device 112 may be referred to as the keyboard 112 or the mouse 112.

[0029] The storage unit 106 stores various databases, tables, files, and the like. The storage unit 106 records computer programs for cooperating with an OS (Operating System) to give instructions to a CPU (Central Processing Unit) to perform various processes. For example, memory devices such as RAM (Random Access Memory) and ROM (Read Only Memory), fixed disk devices such as hard disks, flexible disks, and optical disks can be used as the storage unit 106. The storage unit 106 includes a status matching master 106a and an inventory database 106b.

[0030] The status matching master 106a is a master that sets the status of the product. Here, the status matching master 106a may be set by matching the product status indicating whether it is a normal product, awaiting evaluation by the supplier, or after evaluation by the supplier, and the shipping possibility category indicating whether it can be shipped.

[0031] The inventory database 106b stores inventory data of products. Here, the inventory database 106b may store inventory data that is set by linking the product status (product, regular product, awaiting evaluation by the supplier, or after evaluation by the supplier), the number of stocks, and the last arrival date. In addition, the inventory data may be set by linking the lot number.

[0032] The control unit 102 is a CPU or the like that performs overall control of the returned goods inventory management device 100. The control unit 102 has an internal memory for storing control programs such as an OS, programs that define various processing procedures, required data, etc., and executes various information processing based on these stored programs. In terms of functional concepts, the control unit 102 includes a sales acquisition unit 102a, a status change unit 102b, an inventory registration unit 102c, an instruction acquisition unit 102d, and an inventory inquiry unit 102e.

[0033] The sales acquisition unit 102a acquires sales data of a product. Here, the sales acquisition unit 102a may acquire sales data that is set by linking the product status, the sales date including the return date, and the sales number including the number of returns. The sales acquisition unit 102a may also identify the product status based on the status linking master 106a, and acquire sales data that is set by linking the status, the sales date including the return date, and the sales number including the number of returns.

[0034] The status change unit 102b acquires status change data that sets a request to change the status of the inventory data. Here, when the appraisal of a product waiting for appraisal at a supplier is completed, the status change unit 102b may acquire status change data that sets the post-change status of the product and the number of changes.

[0035] The inventory registration unit 102c registers inventory data. Here, the inventory registration unit 102c may register the inventory data based on sales data. The inventory registration unit 102c may also update the inventory data based on status change data. The inventory registration unit 102c may also update the last arrival date set in the inventory data to blank when the inventory quantity set in the inventory data becomes 0 based on the status change data.

[0036] The instruction acquisition unit 102d acquires an inventory inquiry instruction for a product. Here, the instruction acquisition unit 102d may acquire a retained inventory inquiry instruction set by linking a reference product and a reference status. The instruction acquisition unit 102d may also acquire a retained inventory inquiry instruction set by linking a reference period, a reference product, and a reference status.

[0037] The inventory inquiry unit 102e displays inventory inquiry detail data. Here, the inventory inquiry unit 102e may display the slow inventory inquiry detail data set by linking the inventory quantity of the inquiry product in the inquiry status with the slow inventory period based on the inventory data and the slow inventory inquiry instruction. The inventory inquiry unit 102e may also display the slow inventory inquiry detail data set by linking the inventory quantity of the inquiry product in the inquiry status with the slow inventory period that satisfies the inquiry period based on the inventory data and the slow inventory inquiry instruction. The inventory inquiry unit 102e may also display the slow inventory inquiry detail data set by linking the inventory quantity of the inquiry product in the inquiry status for each lot number with the slow inventory period based on the inventory data and the slow inventory inquiry instruction.

[0038] [3. Specific Examples] A specific example of this embodiment will be described with reference to FIGS.

[0039] [Return inventory management processing] An example of returned stock management processing in this embodiment will now be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of processing of the returned stock management device 100 in this embodiment.

[0040] As shown in FIG. 5, when the user sets the sales date and the number of returns via the input device 112, the sales acquisition unit 102a identifies the status of the product based on the status linking master 106a, and acquires sales data set by linking the status, the sales date including the return date, and the sales number including the number of returns (step SA-1).

[0041] Then, the inventory registration unit 102c registers inventory data of the product in the inventory database 106b based on the sales data (step SA-2).

[0042] Then, when the appraisal of the product waiting for appraisal at the supplier is completed, the status change unit 102b acquires the status change data in which the post-change status of the product and the number of changes are set (step SA-3).

[0043] Then, the inventory registration unit 102c updates the inventory data stored in the inventory database 106b based on the status change data (step SA-4).

[0044] Then, when the user sets the inquiry period, the queried item, and the inquiry status on the slow-moving inventory inquiry screen via the input device 112, the instruction acquisition unit 102d acquires the slow-moving inventory inquiry instruction that is set in association with the inquiry period, the queried item, and the inquiry status (step SA-5).

[0045] Then, based on the inventory data stored in the inventory database 106b and the delayed inventory inquiry instruction, the inventory inquiry unit 102e causes the output device 114 to display the delayed inventory inquiry detail data, which is set by linking the inventory quantity for each lot number of the inquired product in the inquiry status and the delayed inventory period (step SA-6), and ends the processing.

[0046] Here, an example of returned goods inventory management processing in this embodiment will be described with reference to Fig. 6 to Fig. 9. Fig. 6 to Fig. 9 are diagrams showing an example of returned goods inventory management processing in this embodiment.

[0047] In this embodiment, when the status linking master 106a is set as shown in Fig. 6 and inventory data of the product is registered in the inventory database 106b, as shown in Fig. 7, in the event of a sale or return, the sales data is acquired and the inventory data is registered in the inventory database 106b based on the sales data. Here, as shown in Fig. 7, in this embodiment, in the event of a return, the status of the sales data is automatically set to "1: waiting for appraisal." Also, in this embodiment, when entering sales or shipment, an error message is output for inventory with status = "1: waiting for appraisal" (inventory registration not possible), and a warning message is output for inventory with status = "2: after appraisal" (inventory registration possible).

[0048] In this embodiment, as shown in Fig. 8, a request for appraisal of the returned item is made to the supplier, and when the appraisal is completed by the supplier, status change data is acquired and the status set in the inventory data of the returned item is changed to a rank that allows shipment, as shown in Fig. 9. Here, in this embodiment, as shown in Fig. 9, when the inventory quantity set in the inventory data becomes 0, the last arrival date set in the inventory data is deleted.

[0049] An example of the slow inventory confirmation process in this embodiment will be described with reference to Fig. 10. Fig. 10 is a diagram showing an example of the slow inventory confirmation process in this embodiment.

[0050] As shown in FIG. 10, in this embodiment, the period from arrival to shipment is considered to be retention, and the most recent arrival date for each product is compared with the current accounting year and month, and the difference in months is determined as the retention month. That is, as shown in FIG. 10, in this embodiment, for a product with product code: S0001, arrival occurred most recently on 2023 / 1 / 15, and as of May 2023, shipment has not yet occurred. Therefore, the retention month is determined to be "4 (months)" based on the formula "month of current accounting year and month - month of last arrival date". Here, in this embodiment, even if the last arrival date is 2023 / 1 / 28, the retention month will be the same "4". In addition, in this embodiment, the current accounting year and month is obtained from the basic information table.

[0051] As shown in Figure 10, in this embodiment, a backlog inventory inquiry screen is output based on the basic information table and inventory data, and the items "Status" to "Number of months backlogged" at the top of the screen set by the user become the extraction conditions for retrieving data, and data narrowed down by the extraction conditions is output in the details section.

[0052] [4. Contribution to the United Nations-led Sustainable Development Goals (SDGs)] This embodiment can contribute to improving business efficiency and promoting appropriate management decisions by companies, thereby contributing to goals 8 and 9 of the SDGs.
