<p><P>PROBLEM TO BE SOLVED: To provide a failure probability calculation device, method, and program obtaining failure probability of equipment by using only failure records and the like obtained after the equipment starts operation. <P>SOLUTION: A reliability analysis part 15 obtains a failure rate curve according to a reliability analysis by using a failure record of a population to be a set of equipment regarded as a same kind with specific equipment among a plurality of equipment and obtains the failure rate when the specific equipment is used. An incidence calculation part 16 obtains a sub-set of equipment being used at the same level as the specific equipment among the population and, in this sub-set, obtains an incidence of the equipment indicating a measurement value of the same level as the specific equipment and an incidence of the equipment indicating the measurement value of the same level as the specific equipment actually in failure. A failure probability calculation part 17 obtains the failure probability of the specific equipment by using the failure probability obtained by the reliability analysis part 15 and the incidence obtained by the incidence calculation part 16. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
