A Chance Constrained Model for a Two Units Series Critical System Suffering From Continuous Deterioration

In this paper we focus on a continuously deteriorating two units series equipment which its failure can not be measured by cost criterion. For these types of systems avoiding failure during the actual operation of the system is extremely important. In this paper we determine inspection periods and maintenance policy in such a way that failure probability is limited to a pre-specified value and then optimum policy and inspection period are obtained to minimize longrun cost per time unit. The inspection periods and maintenance policy are found in two phases. Failure probability is limited to a prespecifiedvalue In the first phase, and in the second phase optimum maintenance thresholds and inspection periods are obtained in such a way that minimize long-run expected.
