Title: FAILURE RISK INDEX ESTIMATION DEVICE AND FAILURE RISK INDEX ESTIMATION METHOD
Abstract:
A model formula construction unit (4a) constructs a model formula that indicates a transition of a failure risk index according to a statistical distribution, on the basis of an FMEA result read from an FMEA result database (2) and statistic evaluation information A. On the basis of information read from the FMEA result database (2) and a predetermined operation interval database (3), a parameter estimation unit (4b) statistically estimates such a parameter value of the model formula that a difference between a maintenance operation interval calculated from the model formula and a predetermined maintenance operation interval is minimized.
