MONITORING METHOD, MONITORING DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2015/177840

A1

[Problem] To propose a monitoring method, a monitoring device, and a storage medium, whereby it is possible to readily provide the results of detection processing of a sign of future failure. [Solution] The present invention obtains measured values of a plurality of indices including reference indices and target indices from a system to be monitored, calculates predicted values of the reference indices, which are future values of the reference indices, on the basis of the measured values of the plurality of indices, then generates a system model of the system to be monitored and a sub-model which is a part of the system model, and estimates, on the basis of the predicted values of the reference indices and the generated sub-model, the probability that a measured value of each target index is equal to a predetermined value or falls within a predetermined range of values.
