Maintenance system and method and program therefor
First Claim
1. A maintenance system that calculates a timing to make a visit for maintenance work of consumable parts of a machine to be maintained;
- the system comprising;
a visit-interval calculating section for calculating a visit interval to make a visit for maintenance work for each consumable part on the basis of a failure rate distribution;
a replacement-interval calculating section that calculates a replacement interval to replace the consumable parts for each consumable part on the basis of the failure rate distribution; and
a visit-timing calculating section that calculates a timing to actually visit the machine to be maintained on the basis of the visit interval calculated by the visit-interval calculating section and the replacement interval calculated by the replacement-interval calculating section.

Abstract
To provide a technique of reducing the costs for maintenance work and also the downtime of products. There is provided a maintenance system that calculates a timing to make a visit for maintenance work for consumable parts of a machine to be maintained. The maintenance system includes: a visit-interval calculating section for calculating a visit interval to make a visit for maintenance work for each consumable part on the basis of a failure rate distribution; a replacement-interval calculating section for calculating a replacement interval to replace the consumable parts for each consumable part on the basis of the failure rate distribution; and a visit-timing calculating section for calculating a timing to actually visit the machine to be maintained on the basis of the visit interval calculated by the visit-interval calculating section and the replacement interval calculated by the replacement-interval calculating section.

9. A maintenance method for calculating a timing to make a visit for maintenance work of consumable parts of a machine to be maintained, the method comprising:
-
a failure-rate-distribution calculating step of calculating the failure rate distribution of each consumable part on the basis of maintenance historical data, that is, history information on maintenance work performed for the machine to be maintained; a visit-interval calculating step of calculating a visit interval to make a visit for maintenance work for each consumable part on the basis of the failure rate distribution calculated in the failure-rate-distribution calculating step and the maintenance historical data; a replacement-interval calculating step of calculating a replacement interval to replace the consumable parts for each consumable part on the basis of the failure rate distribution calculating in the failure-rate-distribution calculating step and the maintenance historical data; and a visit-timing calculating step of calculating a timing to actually visit the machine to be maintained on the basis of the visit interval calculated in the visit-interval calculating step and the replacement interval calculated in the replacement-interval calculating step. - View Dependent Claims (10, 11, 12, 13, 14)

15. A computer-readable storage medium storing a maintenance program for a computer to execute a process of calculating a timing to make a visit for maintenance work for consumable parts of a machine to be maintained, the maintenance program including instructions which, when executed, cause the computer to perform actions comprising:
-
a failure-rate-distribution calculating step of calculating the failure rate distribution of each consumable part on the basis of maintenance historical data, that is, history information on maintenance work performed for the machine to be maintained; a visit-interval calculating step of calculating a visit interval to make a visit for maintenance work for each consumable part on the basis of the failure rate distribution calculated in the failure-rate-distribution calculating step and the maintenance historical data; a replacement-interval calculating step of calculating a replacement interval to replace the consumable parts for each consumable part on the basis of the failure rate distribution calculated in the failure-rate-distribution calculating step and the maintenance historical data; and a visit-timing calculating step of calculating a timing to actually visit the machine to be maintained on the basis of the visit interval calculated in the visit-interval calculating step and the replacement interval calculated in the replacement-interval calculating step. - View Dependent Claims (16, 17, 18, 19, 20)
