Analysis of a Repairable System Subjected To Multiple Modes of Failure

Abstract Systems deteriorate over time and hence require maintenance. This paper discusses the operational performance of a repairable system subjected to several modes of failure. Unlike many models in the literature, where after each failure the system is perfectly repaired (replaced), it is assumed here that the system performance is declined after each failure, i.e., the performed repairs are imperfect. The paper presents a closed form expression for the long term probability that the system operates in the operational state.
