摘要

A comparison expression calculator (10) calculates a comparison expression by performing approximate calculation on data strings each connecting the value of a subject factor changing according to a user or an environment to an applied stress measurement measured when a subject apparatus is used. An applied load calculating means (20) calculates an applied load applied to the subject apparatus in accordance with the comparison expression and index data on the subject factor. A failure rate calculating means (40) calculates a failure rate of the subject device according to the applied load and a characteristic value distribution of the subject device.
