EQUIPMENT PERFORMANCE EVALUATION DEVICE, EQUIPMENT PERFORMANCE EVALUATION METHOD, AND EQUIPMENT PERFORMANCE EVALUATION PROGRAM

WIPO Patent Application WO/2023/047841

A1

This equipment performance evaluation device comprises: an overall performance function acquisition unit configured to obtain an overall performance function indicating a change in the performance index of equipment to be evaluated over time, on the basis of data acquired during operation of the equipment to be evaluated; an individual performance function definition unit configured to define a plurality of individual performance functions respectively indicating changes in the performance index over time caused by a plurality of change factors of the performance index; and a model creation unit configured to create a performance estimation model of the equipment to be evaluated by superimposing the plurality of individual performance functions, the model creation unit being configured to determine coefficients of each of the plurality of individual performance functions in the superposition such that the superposition of the plurality of individual performance functions approximates the overall performance function.
