Simulation based reliability analysis of phased-mission system considering maintenance in system-level

In this paper, we presented a simulation based model to analysis the reliability of phased-mission system (PMS) with repairable components. Many researches on the repairable PMS supposed that failed components would be repairable only when the system is in a good state. It is different here that failed components can be repaired no matter what state is the system in. The mission successes if and only if the sum of Phase Work Time and Phase Maintenance Time is less than the limited time. The simulation model is an efficient method when the system becomes more and more complex. It can also solve the problem when the components' life and maintenance time have different distributions from exponential.
