• Marginal checking of a Markovian degradation unit is treated when time interval to the next checking is not fixed but obeys a certain general distribution. The problem of determing the optimal set of the states at which the unit is replaced with a new one (marginal set) is discussed. It is solved by using Markov-renewal programming with modified policy iteration cycle. It is showed that control limit rule holds for the optimal policy. The expected cost associated with preventive maintenance and corrective maintenance when the unit is operated in an infinite time span (cost rate) is derived. The unimodality of the cost rate with respect to the control limit is discussed, and a necessary and sufficient condition for preventive replacement to be effective is given.
