为了给可修部件预防性维修提供科学合理的理论依据，基于随机理论中的连续时间马尔科夫过程，建立了可修部件的预防性维修模型，分析和仿真了预防性维修模型中的维修率及检查率变化对模型稳态值影响。基于可修部件的预防性维修模型，也就是其状态转移图，计算出预防性维修模型的稳态值，分析检查率及维修率对稳态值影响，得出维修率及检查率对可修部件预防性维修模型影响的理论依据。最后借助Matlab软件对所分析出的结果进行了仿真验证。结果表明，理论分析与仿真结果是一致的。明白参数对可修部件预防性维修模型稳态值的影响对正确的选取参数，从而对获得期望的稳态值有一定的帮助。

In order to provide the scientific and reasonable theoretical basis for preventive maintenance of repairable part, based on continuous time markov process, repairable part’s preventive maintenance model is established, and the repair rate and checking rate’s influence on preventive maintenance model are analyzed and simulated in this paper. Based on it’s preventive maintenance model, i.e. it’s state transition diagram, it’s steady state values are calculated, and the repair rate and checking rate’s influence on preventive maintenance model are analyzed, and these are theoretical basis. At last, with the help of Matlab software, the analysis of the results are simulated. The results show that theoretical analysis and simulation results are consistent. To understand the parameters’s influence on stability index for selecting correct parameters to obtain the desired steady-state values has some help.
