That is, as the procedure S1 in FIG. 2, the maintenance department 3 sends the part delivery request information (part number specifying the part, customer name to which the part is delivered, and the number of parts, etc.) to arrange the necessary parts in the terminal device. 3A, the component delivery request information is transmitted to the information processing apparatus 1a of the component management section 1 via the network 5, so that the component inventory information is extracted from the component inventory information section 6c of the database 7 as step S2. In step S3, the part reproduction information is extracted from the part reproduction information section 6b, and in step S4, the customer information is extracted from the customer information section 6a. It is determined whether there is a delivery designation. As a result, when it is determined that there is a new part delivery designation, as a step S6, a new part delivery is instructed and the part delivery operation is terminated.

On the other hand, when it is determined in step S5 that there is no new part delivery designation, in step S7, the maintenance contract for the equipment is capable of delivering the recycled part with reference to the customer information. Is determined. Here, there are maintenance contracts that provide all parts free of charge for parts that need to be replaced due to wear or deterioration, and maintenance contracts that provide only consumable parts free of charge. There are maintenance contracts that limit the number of parts to be replaced to new parts and maintenance contracts that can be used with refurbished parts in order to keep the cost of repair parts inexpensive. Is to check if it is.

If it is determined in step S7 that the maintenance contract allows the retrieval of the remanufactured parts, it is determined in step S8 whether the remanufactured parts are in stock by referring to the parts inventory information. As a result, when it is determined that there is a stock of the recycled component, the process proceeds to step S9 in FIG. If it is determined in step S7 that the maintenance contract is not a maintenance contract that allows the retrieval of a recycled part, and if it is determined in step S8 that there is no inventory of the recycled part, the process proceeds to step S6 to instruct the release of a new part.

If it is determined in step S8 that the recycled parts are in stock, in step S9, a rank designation for the use of the recycled parts is performed based on the contract information included in the customer information and the part reproduced information. A rank determination process for determining the presence / absence is performed, and as a result, when a rank is specified for the use of the reproduction component, the reproduction rank is specified by referring to the corresponding rank based on the contract information and the component reproduction information in step S10. Thereafter, in step S11, the reproduction part numbers to be delivered out in the sorted order of the designated rank are selected. Also, when the rank is not specified for the use of the reproduction component in the step S9, the process proceeds to the step S11 to select a reproduction component number to be delivered to the retrieval order in the sort order of the reproduction component. In addition,
When there is no stock of the regenerated parts of the specified rank specified in the above-mentioned step S11, designation of new parts delivery is performed.

Next, as step S12, the customer information and the part history information are referred to, and a collection source confirming process for comparing the customer code of the collection source of the selected reproduced part with the customer code requiring the part delivery is performed. Here, equipment components, such as printed circuit boards, have different characteristics, and failures may occur due to compatibility with the equipment. By putting a check function to prevent
Do not attach the recycled parts to the same equipment again,
The same failure is prevented from recurring.

If the result of the determination in step S12 is that the customer code of the source of the reclaimed parts is the same as the customer code for which the parts need to be delivered, the procedure goes to step S13 where the customer code is excluded from the candidates for the delivery of the parts. Return. When the customer code of the source of the reclaimed parts is different from the customer code requiring the part delivery in the above step S12, in step S14, a delivery part designation is performed by designating the number of the part to be delivered and a series of part delivery operations. To end.
