[0018] Embodiments of the present invention will be described in detail based on the drawings. Note that the present invention is not limited to these embodiments.

[0019] [1. Overview] First, an overview of the present invention will be described.

[0020] Conventionally, in the building materials industry, inventory management by size such as width, length, and thickness for the same product is an essential requirement. Since the unit of size is unified within the company, there are cases where it is different from the unit of transactions with customers. Specifically, in the construction field, there are cases where "shaku" is used. Although the size management within the company is carried out in "cm", when conducting transactions with customers in shaku, since 3 shaku is converted to 90.909 cm, when searching for inventory, it is not known whether the inventory is registered in 90 cm or 91 cm, so it is necessary to search both sizes, making the operation inefficient and complicated. Also, conventionally, in order to perform a search considering the decimal places during unit conversion, a From~To search could be considered, but a From~To search was required even for product types where no unit conversion occurred.

[0021] Therefore, in this embodiment, even in cases where the customer management unit is not registered in the customer master (sales destination master), the inventory search will be performed using the company's own management unit, but a mechanism is provided that will still find a hit in the search as long as the size error of the search value is within the acceptable range set in the master. For example, in this embodiment, when converting from shaku to centimeters, the product will be found whether you search using 90 cm or 91 cm, so you can search efficiently without worrying about rounding up, rounding down, or rounding to the nearest whole number during unit conversion.

[0022] Furthermore, in this embodiment, (1) the size units managed by the trading partner can be registered on the trading partner master screen. Also, in this embodiment, (2) a unit conversion master and a tolerance range master are provided and parameters can be set for unit conversion or tolerance range search after unit conversion. In this embodiment, in order to allow for batch adjustment in cases where tolerance range is unnecessary, the tolerance range is too wide, or the tolerance range is too narrow for products other than those related to construction, the tolerance range can be set on a per-product basis. Also, in this embodiment, (3) when searching by sales destination and size as extraction conditions on the inventory search screen, the search is performed using the size units managed by the trading partner, converted to the company's size units, and inventory within the tolerance range can be displayed as a search result. In this embodiment, if a sales destination is not specified in the extraction conditions, the search will be performed using the company's size units instead of the trading partner's size units, but even in this case, inventory within the tolerance range can be displayed as a search result.

[0023] [2. Structure] An example of the configuration of the inventory search device 100 according to this embodiment will be described with reference to Figures 1 to 6. Figure 1 is a block diagram showing an example of the configuration of the inventory search device 100 in this embodiment.

[0024] As shown in Figure 1, the inventory search device 100 is a commercially available desktop personal computer. However, the inventory search device 100 is not limited to stationary information processing devices such as desktop personal computers, but may also be portable information processing devices such as commercially available notebook personal computers, PDAs (Personal Digital Assistants), smartphones, or tablet personal computers.

[0028] The storage unit 106 stores various databases, tables, and files. The storage unit 106 also stores computer programs that work in cooperation with the OS (Operating System) to give instructions to the CPU (Central Processing Unit) to perform various processes. The storage unit 106 can be, for example, a memory device such as RAM (Random Access Memory) or ROM (Read Only Memory), a fixed disk device such as a hard disk, a flexible disk, or an optical disk. The storage unit 106 includes an inventory management database 106a.

[0029] The inventory management database 106a stores inventory management data. Here, the inventory management database 106a may store current inventory data linked to products, inventory size and inventory quantity according to the company's management units, a customer master with customer management units set for each customer, a unit conversion master with conversion values ​​according to the company's management units for each customer management unit, and / or a tolerance range master with tolerance values ​​that define the size tolerance range of products. The inventory management database 106a may also store a product master linked to products and product types. The tolerance range master may also be set linked to product types and tolerance values. The company's management units may be millimeters, centimeters, meters, inches, hands, feet, yards, chains, rin, bu, sun, shaku, ken, jo, or cho. The customer management units may also be millimeters, centimeters, meters, inches, hands, feet, yards, chains, rin, bu, sun, shaku, ken, jo, or cho. Furthermore, the goods may be building materials or enamel products. In addition, the inventory management database 106a may store order data, sales data, purchase data, incoming goods data, and / or outgoing goods data.

[0030] Here, an example of the data structure in this embodiment will be described with reference to Figures 2 to 6. Figures 2 to 6 are diagrams showing an example of the data structure in the embodiment.

[0031] As shown in Figure 2, this embodiment includes a customer master (sales customer master) that links customer codes (sales customer codes), customer names (sales customer names), and customer management units (customer units). As shown in Figure 2, Company I uses the same CM management as the company itself, so the customer unit is not registered (NULL).

[0032] As shown in Figure 3, this embodiment includes a unit conversion master in which the source unit and the converted value are linked and set.

[0033] As shown in Figure 4, this embodiment includes a product master in which product codes, product names, and variety codes are linked and configured.

[0034] As shown in Figure 5, this embodiment includes a tolerance range master in which a variety code and an tolerance value are linked and set.

[0035] As shown in Figure 6, the inventory management database 106a of this embodiment stores current inventory data linked to the storage location (warehouse), product code, product name, lot number, width, length, and inventory quantity.

[0036] Returning to Figure 1, the control unit 102 is a CPU or similar component that comprehensively controls the inventory search device 100. The control unit 102 has internal memory for storing control programs such as the OS, programs that define various processing procedures, and required data, and executes various information processing based on these stored programs. Functionally, the control unit 102 comprises an order acquisition unit 102a and an inventory search unit 102b.

[0037] The order acquisition unit 102a acquires order data. Here, the order acquisition unit 102a may acquire order data that is set by linking the order size and order quantity of goods from the trading partner. Alternatively, the order acquisition unit 102a may acquire order data that is set by linking the order size and order quantity of goods for each trading partner management unit from the trading partner.

[0038] The inventory search unit 102b performs an inventory search. The inventory search unit 102b may output (display or print) the inventory search results. The inventory search unit 102b may also display inventory search results that are set by linking the inventory size and inventory quantity of inventory items based on order data, current inventory data, customer master, unit conversion master, and tolerance range master. Alternatively, the inventory search unit 102b may convert the order size of the customer management unit set in the order data to the converted size of the company's management unit using the conversion value set in the unit conversion master for the customer management unit set in the customer master, and then display inventory search results that are set by linking the inventory size and inventory quantity of inventory items based on the converted size, current inventory data, and tolerance range master. Furthermore, the inventory search unit 102b may convert the order size of the customer management unit set in the order data to the converted size of the company's own management unit using the conversion value set in the unit conversion master for the customer management unit set in the customer master, identify current inventory data for which the inventory size is set within the size tolerance range from the lower limit obtained by subtracting the tolerance value set in the tolerance range master from the converted size to the upper limit obtained by adding the tolerance value to the converted size, identify inventory search results set by linking the inventory size and inventory quantity of the inventory product from the current inventory data, and display the inventory search results. In addition, if the input size of the product is set in the company's own management unit, the inventory search unit 102b may display inventory search results set by linking the inventory size and inventory quantity of the inventory product based on the input size, current inventory data, and tolerance range master. Furthermore, when the inventory search unit 102b obtains order data from a customer whose company management unit is set as the customer management unit in the customer master by the order acquisition unit 102a, it may identify current inventory data in which the inventory size is set within a size tolerance range from the lower limit obtained by subtracting the tolerance value set in the tolerance range master from the order size set in the order data to the upper limit obtained by adding the tolerance value to the order size, and then display the inventory search results that associate the inventory size and inventory quantity of the inventory items based on the current inventory data.Furthermore, the inventory search unit 102b may convert the order size of the customer management unit for the product set in the order data to the converted size of the company's management unit using the conversion value set in the unit conversion master for the customer management unit set in the customer master, identify the product variety set in association with the product in the product master, identify the tolerance value set in association with the product variety in the tolerance range master, identify the current inventory data in which the inventory size is set within the size tolerance range from the lower limit obtained by subtracting the tolerance value from the converted size to the upper limit obtained by adding the tolerance value to the converted size, identify the inventory search result set in association with the inventory size and inventory quantity of the inventory product from the current inventory data, and display the inventory search result.

[0039] [3. Specific Examples] A specific example of this embodiment will be described with reference to Figures 7 to 9.

[0040] [Inventory management processing] Now, with reference to Figure 7, an example of inventory management processing in this embodiment will be described. Figure 7 is a flowchart showing an example of processing by the inventory search device 100 in this embodiment.

[0041] As shown in Figure 7, the order acquisition unit 102a acquires order data from a trading partner, linking the order size and order quantity of the trading partner management unit for the goods (Step SA-1).

[0042] Then, the inventory search unit 102b converts the order size of the customer management unit for the product set in the order data to the converted size of the company's management unit using the conversion value set in the unit conversion master for the customer management unit set in the customer master, identifies the product type set in association with the product in the product master, identifies the tolerance value set in association with the product type in the tolerance range master, identifies the current inventory data in which the inventory size is set within the size tolerance range from the lower limit obtained by subtracting the tolerance value from the converted size to the upper limit obtained by adding the tolerance value to the converted size, identifies the inventory search result set in association with the inventory size and inventory quantity of the inventory product from the current inventory data, displays the inventory search result on the output device 114 (step SA-2), and ends the process.

[0043] Here, an example of inventory management processing in this embodiment will be described with reference to Figures 8 and 9. Figures 8 and 9 are diagrams showing an example of inventory management processing in this embodiment.

[0044] As shown in Figure 8, in this embodiment, when an order data for 100 sheets of "1x3" size MDF is obtained from Company H, (1) Company H's customer code is set as the planned customer on the inventory inquiry screen to identify the customer unit registered in the customer master, (2) the size of the customer unit is set on the inventory inquiry screen, and (3) the unit is converted from shaku to cm using the conversion value from the unit conversion master, the product type is referenced from the product code in the product master, and a from~to inventory search is performed using the tolerance value + / - from the tolerance range master.

[0045] Furthermore, as shown in Figure 9, in this embodiment, when an order data for 100 sheets of "1x3" size MDF is obtained from Company H, and the user has converted the input size (cm) from "1 (shaku) x 3 (shaku)" and set it on the inventory inquiry screen, (1) the product code is used to refer to the product type in the product master, and a from~to inventory search is performed using the tolerance value of the tolerance range master by adding / subtracting.
