FACILITY EVALUATION DEVICE, FACILITY EVALUATION METHOD AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To evaluate performance degradation of a facility over a long period considering the whole life cycle.SOLUTION: A facility evaluation system includes: estimation means for estimating a probability density distribution of a parameter indicating performance of an object facility on the basis of measurement data of the object facility measured until each of a plurality of time points; acquisition means for acquiring a use pattern of the object facility; storage means for storing the use pattern by associating it with the probability density distribution of the object facility; and evaluation means for specifying the use pattern of the object facility similar to the use pattern of a first facility that is different from the object facility and evaluating the performance degradation in future of the first facility by using a probability density distribution group corresponding to the specified use pattern.SELECTED DRAWING: Figure 1
