FAILURE RISK ASSESSMENT SYSTEM AND FAILURE RISK ASSESSMENT METHOD

摘要

A failure risk assessment system equipped with: a history acquisition unit for acquiring the failure history of an overall system comprising a plurality of sub-systems and the maintenance history of one or more sub-systems selected from among the plurality of sub-systems; and a failure risk assessment model calculation unit which obtains the failure risk of a sub-system for which there is no maintenance history by calculating a failure risk assessment model for assessing the failure risk of said sub-system on the basis of the failure history of the overall system and the acquired maintenance history of the one or more sub-systems.
