PROBLEM TO BE SOLVED: To provide a method for sorting reusable components. SOLUTION: A component whose performance is equal to or more than a predetermined sorting performance Pon2Las, V2Las is sorted for reuse in operation performance Pon1, V1 of the total number (u) of components used in a first period W1. For setting the sorting performance Pon2Las, a component after use for the first period W1 is subjected to an accelerated degrading test for a second period W2, and the operation performance Pon2, V2 is measured. A distribution function approximated regarding the performance of components is found to determine, for example, a normal distribution. Based on the expression of the distribution function, accumulation probability qon2Las, where the operation performance Pon2 is given by Pon2Lar≤Pon2, is calculated for each performance Pon2Lar in a plurality of (k) types. A setting performance Pon2Las that is less than a first accumulation probability qonOLa and corresponds to a value qon2Las closest to the first accumulation probability qon1L is selected as sorting performance in the accumulation probability qon2Las.
