To aim at some large-size complex equipments widely used in industrial enterprises, this paper analyzed the operation maintenance and management feature, and established the full life cycle model with four states, and then performed the reliability and security analysis on it. During modeling we not only considered all the possibly emerging states of the equipment such as working, storage, preventive maintenance, and corrective maintenance, but also still conducted the detailed analysis on the transfer relations among these states. Based on it, we constructed the non-Markov process model of the equipment, where the checking and repairing time were considered to follow the arbitrary distribution during preventive maintenance and corrective maintenance, and the failure time distribution was thought to be exponential. Hence, by the use of supplementary variables, we converted the non-Markov model into the Markov process model, and calculated the relative reliability and security indexes. Compared with classical two-state and three-state models, the results show the established model is accurate and effective, and possesses a broad adaptability.
