DEVICE AND METHOD FOR PREDICTING RELIABILITY AND MAINTENANCE COST OF APPARATUS

Japanese Patent JP2023108670

A

To provide a device and method for predicting reliability and maintenance costs of an apparatus, which can improve reliability of a facility and reduce maintenance costs.SOLUTION: A device 10 for predicting reliability and maintenance costs of an apparatus includes evaluation object setting means 11, failure rate input means 12, maintenance characteristic input means 13, cost input means 14, a basic condition generation unit 15, operation and maintenance record input means 16, operation and maintenance schedule input means 17, plotting means 18, evaluation condition input means 19, and simulation means 20. The simulation means 20 calculates a time function of a failure rate of the apparatus based on records and schedules of operation and maintenance, a time function of maintenance costs, and a time function of an expected value of failure recovery costs and locates them with respect to time. The evaluation condition input means 19 designates an evaluation period and changes the schedule of maintenance or operation located with respect to time by the plotting means 18.SELECTED DRAWING: Figure 1
