Abstract:

In order to improve the mission completion capability of complex multi-state system, reducing maintenance resource consumption, a maintenance decision method for multi-state system based on Semi-Markov model were provided, using Semi-Markov model describes the degradation process of components, the universal generating function was used to analyze the reliability indicator of system. Based upon the imperfect maintenance decision model, from "the perspective of system maintenance", an imperfect maintenance decision method is proposed combined preventive maintenance with corrective maintenance, ensure that the system obtains maximum net benefit in the limited service period. and verification and illustration are conducted with aero-engine compressor subsystem. This method can effectively combine preventive maintenance and corrective maintenance advantages, enhances the mission completion capability of system, and has a strong versatility and engineering application value.

Key words: multi-state system, Semi-Markov model, preventive maintenance, corrective maintenance, maintenance decision
