Abstract:
A method of evaluating a failure occurrence likelihood of a manufacturing workshop, comprising:a workshop database preparation step of creating previously a workshop evaluating database to be stored for preparation, said workshop evaluating database indicating correspondence relations between a plurality of workshop-conditioned failure influential items set previously and failure occurrence ratio indexes at least for standard manufacturing works at standard workshop facility levels for said workshop-conditioned failure influential items, respectively; a step of extracting from said workshop evaluating database prepared in said workshop database preparation step those failure occurrence ratio indexes which correspond to workshop facility levels of an inputted evaluation-undergoing manufacturing workshop for the workshop-conditioned failure influential items, respectively; and a workshop evaluation step of evaluating through estimation the failure occurrence likelihood in said evaluation-undergoing manufacturing workshop by totalizing the extracted failure occurrence ratio indexes for a plurality of concerned workshop-conditioned failure influential items to thereby determine arithmetically the indexes indicating the failure occurrence ratios for the standard manufacturing works, respectively, in said evaluation-undergoing manufacturing workshop.
