In these systems, a deterioration limit is usually pre-determined for each part and the considered part is replaced while reaching this limit. In this paper, replacement conditions of these parts were examined according to the replacement times in the past. Using dynamic programming, for every deterioration rate of part 1, there is a deterioration limit for part 2, after which either part 2 or both parts should be replaced.
