First, the control unit 22 of the maintenance management device 20 sets the maintenance contract database 32 or the parts during a predetermined time predetermined from the previous determination (in the case of the first time, when the maintenance contract database 32 is first registered). It is determined whether or not the contents of the inventory database 36 have changed (step B1 in FIG. 11). If there is no change in the content (NO in step B1), the process ends.

When the content changes (YES in step B1), the control unit 22 of the maintenance management device 20 identifies each maintenance target device based on the maintenance contract database 32, and determines the quantity of each specified maintenance target device. Calculate (step B2 in FIG. 11).

Next, the control unit 22 of the maintenance management device 20 identifies each replacement component with reference to the replacement component database 37 based on each maintenance target device identified in step B2 (step B3 in FIG. 11).

Next, the control unit 22 of the maintenance management device 20 refers to the failure history database 39 based on the quantity of each maintenance target device calculated in step B2 and each replacement part specified in step B3. The appropriate inventory quantity (appropriate inventory quantity) of each replacement part is calculated (step B4 in FIG. 11).

Here, in the calculation of the appropriate stock quantity of each replacement part, the number of each replacement part is calculated with reference to the failure history database 39 based on each replacement part specified in step B3, and each replacement is calculated. This is performed by accumulating the quantity of each maintenance target device calculated in step B2 corresponding to the number of parts.

Next, the control unit 22 of the maintenance management device 20 calculates the actual inventory quantity (actual inventory quantity) of each replacement part with reference to the parts inventory database 36 based on each replacement part specified in step B3. (Step B5 in FIG. 11).

Next, the control unit 22 of the maintenance management device 20 determines whether or not the actual inventory quantity of each replacement part is equal to or greater than the appropriate inventory quantity (step B6 in FIG. 11). When the actual inventory quantity of each replacement part is equal to or more than the appropriate inventory quantity (YES in step B6), the replacement parts are not out of stock within a predetermined period, so that the process ends.

If the actual inventory quantity of any of the replacement parts is less than the appropriate inventory quantity (NO in step B6), the control unit 22 of the maintenance management device 20 will run out of stock for the corresponding replacement parts within a predetermined period. , The shortage quantity of replacement parts is calculated from the difference between the actual stock quantity and the appropriate stock quantity for each shortage replacement part (step B7 in FIG. 11).

Next, the control unit 22 of the maintenance management device 20 places an order for adding (ordering) the calculated shortage quantity of replacement parts (a quantity obtained by adding a predetermined quantity to the shortage quantity is also possible) for each shortage replacement part. Generate a calligraphy (step B8 in FIG. 11).

Finally, the control unit 22 of the maintenance management device 20 outputs the generated purchase order (step B9 in FIG. 11), and then ends. Based on the output purchase order, the manager of the maintenance management device 20 will perform paperwork for ordering replacement parts.

The paperwork for ordering may be performed by the control unit 22 of the maintenance management device 20.

In addition, regarding the paperwork of ordering, in the case of parts used only for equipment subject to new maintenance contracts, it is necessary to determine in advance the number of replacement parts for each part due to repair occurrence within a predetermined period from past actual values, etc. The quantity may be ordered. Here, the required quantity is the number of replacements of the parts, and even if a plurality of the replacement parts are replaced in one replacement operation, only one tool is required for the replacement.

In addition, regarding the paperwork of ordering, in the case of common replacement parts that are also used in other equipment, the number of replacement parts due to repairs including other equipment is determined from past actual values, etc., and the required quantity is ordered. You may.

In addition, regarding the paperwork of ordering, the order processing is performed to add the shortage quantity as described above for the increase in the appropriate stock quantity due to the increase in the maintenance contract, and the obtained parts are used for the equipment of the maintenance contract. The address in the maintenance contract database 32 of the above may be sent to the parts warehouse in charge of the address. Here, the warehouse in charge may be the nearest parts warehouse.

In addition, regarding the paperwork of ordering, not only replacement parts but also tools and jigs, using the maintenance contract database 32, parts inventory database 36, and failure history database 39, appropriate inventory quantity and actual inventory of tools and jigs. Calculate and compare the quantity, and if there is a shortage, calculate the shortage quantity for each shortage tool or jig, and perform the order processing to add the shortage quantity of the shortage tool or jig. You may.

In addition, regarding the paperwork of ordering, in the case of tools used only for the maintenance target equipment and replacement parts of the new maintenance contract, the failure history database corresponding to the maintenance target equipment and replacement parts similar to the maintenance target equipment and replacement parts. The appropriate inventory quantity may be calculated with reference to the data in 39, and the shortage quantity, which is the difference from the actual inventory quantity (here, 0), may be ordered.

Further, since the tools are usually used in common among the devices, it is not necessary to increase the number of the devices to be maintained, and it is sufficient to increase the number of maintenance contracts of the devices to be maintained by a predetermined ratio. However, it is necessary to newly obtain tools that are used only for specific equipment and parts. Here, the necessary tool is a tool required for each part, and includes a jig necessary for maintaining the device. In addition, the increase in the number of maintenance contracts is that when parts are replaced by periodic inspections of the same model with the same maintenance contract, the required quantity of tools to be performed at the same location is a maintenance contract that includes equipment subject to maintenance with the same parts. It may be a number. Moreover, the predetermined ratio may be the same number.

In addition, if the number of required tools used at the same time is less than the number of bases in charge corresponding to the warehouse, the warehouse should be shipped together with the necessary tools when parts are used, instead of being stored or inventoried at the base in charge. However, it may be stored or stocked.

Further, when the quantity of tools used at the same time is smaller than the number of parts warehouses, it may be stocked in the parts warehouse.

In addition, even if the number of equipment under maintenance contracts increases, it is not necessary to increase the parts inventory and the quantity of required tools in proportion to it. Determine the inventory quantity of replacement parts and the inventory quantity of tools so that the period from the occurrence of a failure to the recovery will not run out of parts inventory and necessary tools. Here, the period until warehousing is the period until returning the tool in the case of a tool.

According to the first embodiment, it is possible to contribute to suppressing the excess or deficiency of the inventory quantity of replacement parts due to the fluctuation of the maintenance contract. That is, the maintenance management device 20 does not need to increase the inventory quantity of replacement parts in proportion even if the maintenance contract increases, and each replacement part has a period from the average order to warehousing and the occurrence of a failure of the equipment. By setting an appropriate inventory quantity of replacement parts so that the replacement parts will not run out during the period until the restoration of the product, it is possible to prevent excess or deficiency of the replacement parts.
