Abstract
An apparatus for evaluating performance of a device includes: an overall performance function acquisition part configured to obtain an overall performance function which indicates a change over time in performance index of an evaluation target device, based on data acquired during operation of the evaluation target device; an individual performance function definition part configured to define a plurality of individual performance functions each of which indicates a change over time in the performance index caused by a plurality of change factors of the performance index, respectively; and a model generation part configured to generate a performance estimation model for the evaluation target device by performing superposition of the plurality of individual performance functions. The model generation part determines a coefficient of each of the plurality of individual performance functions in the superposition so the superposition of the plurality of individual performance functions becomes close to the overall performance function.
