Publication number: 20210089928Abstract: The remaining life of a component of a mechanical system is predicted with high accuracy. A failure probability evaluation system evaluates a failure of a component of each mechanical system for a mechanical system group including a plurality of mechanical systems, and includes a failure history database for accumulating past failure history data about the mechanical system. A time-series operation database stores time-series physical quantity data representing an operating state of the mechanical system. A failure rate function identification unit calculates a failure rate function of a mechanical system by statistical processing based on the failure history data, and a damage model generation/update unit having a function of generating an explanatory variable expression of a failure rate function which minimizes a variation in life is defined by the failure rate function using the time-series physical quantity data.Type: ApplicationFiled: January 24, 2019Publication date: March 25, 2021Inventor: Yosuke UEKI
