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

Traditionally, scraps and defective products generated in each process have been melted down and used as recycled raw materials (recycled products) for new manufacturing processes. Previously, the melted recycled raw materials were inspected for their components, and the decision on which recycled raw material part number to transfer to in accordance with the specifications was made by human judgment, resulting in a process that was very secular. Furthermore, previously, inventory valuation differed depending on the metal component ratio of the recycled product, so it was necessary to transfer to the correct recycled raw material part number. Furthermore, previously, there were many cases of mistakes in the part number to transfer and processing errors. Furthermore, previously, the part number of the recycled product to transfer to was determined by human judgment based on the inspection results of the re-melted part number, resulting in a lot of secularism and mistakes in the transfer destination.

In this embodiment, we focus on narrowing down the part numbers to be transferred by managing the product number specifications of recycled raw materials in a master file, and on preventing commonality and mistakes caused by listing them. We provide a system that manages the product number specifications of recycled raw materials in a master file and lists the product numbers of recycled raw materials that fall within the specifications based on the inspection results of melted recycled raw materials.

2. Configuration
An example of the configuration of a remanufactured product management device 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of a remanufactured product management device 100 according to this embodiment.

As shown in FIG. 1, the recycled product management device 100 is a commercially available desktop personal computer. Note that the recycled product management device 100 is not limited to a stationary information processing device such as a desktop personal computer, but may also be a portable information processing device such as a commercially available notebook personal computer, PDA (Personal Digital Assistant), smartphone, or tablet personal computer.

The recycled product management device 100 includes a control unit 102, a communication interface unit 104, a memory unit 106, and an input/output interface unit 108. Each unit included in the recycled product management device 100 is connected to each other so that they can communicate with each other via any communication path.

The communication interface unit 104 communicatively connects the recycled product 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 the function of communicating data with other devices via the communication line. Here, the network 300 has the function of connecting the recycled product 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).

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 functions as a pointing device in conjunction with a mouse. Note that, below, 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.

The memory unit 106 stores various databases, tables, files, and the like. The memory unit 106 stores computer programs that work in conjunction with the OS (Operating System) to issue commands to the CPU (Central Processing Unit) to perform various processes. The memory 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 memory unit 106 includes a part number master 106a, an inspection pattern master 106b, and a raw material database 106c.

Product number master 106a is a master that sets product numbers. Here, product number master 106a may set the product number of the recycled raw material or product, and the inspection pattern.

Inspection pattern master 106b is a master that sets inspection patterns for recycled raw materials. Here, inspection pattern master 106b may set inspection patterns that link the components that make up the recycled raw materials and the standard ranges of the components. Furthermore, the components may be metal elements, non-metal elements, inorganic compounds, or organic compounds.

The list acquisition unit 102c acquires recycled raw material candidate list data in which the manufacturing raw materials are set. Here, the list acquisition unit 102c may acquire recycled raw material candidate list data set by linking the manufacturing raw materials with inspection patterns that satisfy the specification range. Furthermore, if the list acquisition unit 102c determines, based on the inspection pattern master 106b, that the blending ratio of each component of the manufacturing raw materials set in the provisional inspection performance data satisfies the specification range of the inspection pattern, it may acquire recycled raw material candidate list data set by linking the manufacturing raw materials with the inspection pattern based on the provisional inspection performance data. Furthermore, the list acquisition unit 102c may display selectable manufacturing raw materials that are compatible with the recycled raw materials set in the recycled raw material candidate list data. Furthermore, the list acquisition unit 102c may output the recycled raw material candidate list data. Furthermore, the recycled raw material candidate list data may be set by linking the lot number and the inspection date. Furthermore, when a lot number and inspection date are set on the recycled raw material candidate list screen, the list acquisition unit 102c may output (display or print out) recycled raw material candidate list data that is set by linking the manufacturing raw material of that lot number inspected on that inspection date and the inspection pattern.

The manufacturing history acquisition unit 102d acquires manufacturing history data that sets the manufacturing history quantity of manufacturing raw materials that are compatible with recycled raw materials. Here, the manufacturing history acquisition unit 102d may acquire manufacturing history data that sets the manufacturing history quantity of manufacturing raw materials that are compatible with recycled raw materials and the input quantity of recycled products (reused products) used in the production of the manufacturing raw materials. Furthermore, when a manufacturing raw material that is compatible with recycled raw materials set in the recycled raw material candidate list data is selected, the manufacturing history acquisition unit 102d may acquire manufacturing history data that sets the manufacturing history quantity of manufacturing raw materials that are compatible with recycled raw materials and the input quantity of recycled products used in the production of the manufacturing raw materials.

The inspection record acquisition unit 102e may also acquire the blending ratio of each component of the manufacturing raw materials that are compatible with the recycled raw materials and the inspection record data set by linking the inspection pattern. The inspection record acquisition unit 102e may also acquire the blending ratio of each component of the manufacturing raw materials that are compatible with the recycled raw materials and the inspection record data set by linking the inspection pattern based on the provisional inspection record data and inventory data.

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

[Recycled product management process]
An example of a remanufactured product management process in this embodiment will now be described with reference to Fig. 2. Fig. 2 is a flowchart showing an example of a process performed by the remanufactured product management device 100 in this embodiment.

As shown in FIG. 2, the provisional inspection performance acquisition unit 102b acquires provisional inspection performance data that sets the blending ratio of each component of the manufacturing raw materials produced by reusing the product (step SA-1).

Then, the list acquisition unit 102c determines, based on the inspection pattern master 106b, whether the composition ratio of each component of the manufacturing raw materials set in the provisional inspection performance data satisfies the specification range of the inspection pattern (step SA-2).

Then, if the list acquisition unit 102c determines that the blending ratio of each component of the manufacturing raw materials set in the provisional inspection performance data does not meet the specification range of the inspection pattern (step SA-2: No), it terminates the process.

On the other hand, if the list acquisition unit 102c determines that the blending ratio of each component of the manufacturing raw materials set in the provisional inspection performance data meets the specification range of the inspection pattern (step SA-2: Yes), it transitions to step SA-3.

Then, the list acquisition unit 102c acquires recycled raw material candidate list data that links manufacturing raw materials and inspection patterns that meet the specification range based on the provisional inspection performance data (step SA-3).

Then, the list acquisition unit 102c prints out the recycled raw material candidate list data, which is linked to the manufacturing raw materials and inspection patterns, via the output device 114 (step SA-4).

Then, when the user selects a manufacturing raw material that is compatible with the recycled raw material set in the recycled raw material candidate list data via the input device 112, the manufacturing history acquisition unit 102d acquires manufacturing history data that sets the production history quantity of the manufacturing raw material that is compatible with the recycled raw material and the input quantity of the recycled product used to produce that manufacturing raw material, and registers inventory data of the manufacturing raw material that is compatible with the recycled raw material in the raw material database 106c based on the manufacturing history data (step SA-5).

Then, based on the provisional inspection performance data and the inventory data stored in the raw material database 106c, the inspection performance acquisition unit 102e acquires the blending ratio of each component of the manufacturing raw material that is compatible with the recycled raw material, and the inspection performance data linked to the inspection pattern (step SA-6), and then ends the process.

Here, an example of the recycled product management process in this embodiment will be described with reference to Figures 3 to 10. Figures 3 to 10 are diagrams showing an example of the recycled product management process in this embodiment.

In this embodiment, as shown in FIG. 3, a product number master 106a is set that links specification data (inspection pattern) to product number data (recycled raw materials), and as shown in FIG. 4, an inspection pattern master 106b is set that manages specifications for each inspection pattern. As shown in FIG. 5, the system manages inventory for scraps and defective products by product number and lot, and when the scraps and defective products are melted to produce recycled raw materials and the blending ratio of metal components in the recycled raw materials is inspected by an analytical device, data on the blending ratio of metal components is shared from the analytical device, as shown in FIG. 6.

In this embodiment, as shown in Figure 7, each inspection item is checked to see if it falls within the specifications (as an example, each inspection pattern is checked for provisional inspection result number = K0001), and all inspection patterns that fall within the specifications are obtained. As shown in Figure 8, recycled raw materials that fall within the specifications are listed for the provisional inspection results.

As shown in Figure 9, in this embodiment, the recycled raw material selected from the candidate list is specified and accepted. Here, as shown in Figure 9, the recycled raw material with lot number: M0001 corresponds to multiple recycled products, but recycled product S002 is specified.

As shown in Figure 10, in this embodiment, inventory is recorded by inputting manufacturing results, and inspection results are entered for that inventory, enabling inspection results management of recycled raw materials (lot units).

An example of the list output process in this embodiment will be described with reference to Figures 11 and 12. Figure 11 is a diagram showing an example of a recycled raw material candidate list screen in this embodiment. Figure 12 is a diagram showing an example of a recycled raw material candidate list in this embodiment.

In this embodiment, when the user sets the lot number and/or analysis date on the recycled raw material candidate list screen as shown in Figure 11, recycled raw material candidate list data is output as shown in Figure 12.
