Abstract
A multi-state degraded system based on the mixed maintenance mode of minimal repairs and incomplete preventive maintenance is studied.Based on the reliability theory and Markov process theo-ry,the operation mode and maintenance mode of the system in a period are analyzed,and the probabilis-tic transition diagram of the system state is drawn.According to the state probabilistic transition dia-gram,differential equation group of state probability is derived.The Laplace transformations formula of state probability is obtained by using the crammer rule in algebra,and then the explicit expression of state probability is derived by Laplace inversion.Finally,the results of the important index of reliability are obtained from the concept of reliability.关键词
