Abstract

A maintenance management system creating inspection plans for an inspection region wherein, a required cost for an inspection of an inspection object included within each management region from among the combinations of deadlines for the inspection of the inspection object included within each management region, and a required cost for inspection of an inspection object including an inspection object which exceeds the deadline for inspection in combinations of the deadlines of each inspection from among the objects for inspection that are included in an inspection cost for the inspection region is compared and one combination from the combinations of deadlines for inspection is output on the basis of the comparison result.

Claims

1. A maintenance management system that creates an inspection plan of inspection objects in a plurality of regions that are categorized, comprising:

a database for storing deadlines for inspections and position information of the inspection objects;

a first calculator for calculating a required cost for an inspection of the inspection object included within the each management region on the basis of the position information; and

a second calculator for calculating a required cost for an inspection of the inspection objects that are specific beyond the management region on the basis of the position information;

wherein the maintenance management system that, among combinations of the deadlines for inspections of the inspection objects included within the each management region, compares the inspection cost of the inspection region that includes a cost calculated by the first calculator and a required cost for an inspection of the inspection objects including an inspection object that exceeds the deadline for inspection in the combinations of the deadlines for inspections within the inspection objects, and

outputs one of the combinations of the deadlines for inspections on the basis of the comparison result.

2. The maintenance management system according to claim 1,

wherein a combination whose cost per unit time is the lowest is output as one among the combinations.

3. The maintenance management system according to claim 1,

wherein the cost calculated by the first calculator and the second calculator is a cost per unit time.

4. The maintenance management system according to claim 1,

comprising a priority calculator that calculates a priority of inspection of the inspection object on the basis of stored information of the database and calculates the deadline for inspection from the calculated priority.

5. The maintenance management system according to claim 4,

wherein the priority calculator calculates the deadline for inspection on the basis of significance when the inspection object fails, failure information by an installation environment of the inspection object, and history information that the inspection object was examined or failed in the past.

6. The maintenance management system according to claim 4,

wherein the deadline for inspection is determined on the basis of the inspection object whose priority is lower than the predetermined threshold and whose priority is also the highest in one inspection region among the plurality of inspection regions.

7. A maintenance management method that creates an inspection plan of inspection objects in a plurality of regions that are categorized, comprising:

a first step of storing deadlines for inspection and position information of the inspection objects;

a second step of calculating a required cost for the inspection of the inspection objects included within the each management region on the basis of the position information;

a third step of calculating a required cost for the inspection of the inspection objects that are specific beyond the management region;

a fourth step of, among combinations of the deadlines for inspections of the inspection objects included within the each management region, comparing an inspection cost of the inspection region that includes a cost calculated in the second step and a cost calculated in the third step required for the inspection of specific inspection objects including an inspection object that exceeds the deadline for inspection in the combinations of the deadlines in the inspection objects; and

a fifth step of outputting one of the combinations of the deadlines for inspections.

8. The maintenance management method according to claim 7,

wherein in the seventh step, a combination whose cost per unit time is the lowest is output as one of the combinations.

9. The maintenance management method according to claim 7,

wherein the inspection cost of the inspection region that is compared in the fourth step is a cost per unit time.
