摘要
由于装备复杂程度的提高以及维修过程的不确定性,对复杂可修系统修复性维修(CM)过程的分析一般基于概念模型进行仿真。通过建立随机的维修功能框图(MFBD),考虑装备测试性设计对维修过程的影响,建立了支持多级多层(MIME)维修活动的仿真模型,同时该模型也支持维修活动间复杂层次及逻辑关系的描述。给出了考虑资源等待时间的复杂可修系统的平均修复时间仿真计算方法,建立了复杂可修系统的修复性维修过程仿真应用案例。通过对测试性设计参数等不同影响因素的调整进行敏感性分析,验证了模型的正确性和适用性。
Due to the increased complexity of the equipment and the uncertainty of the maintenance process,simulation based on a conceptual model is generally used to analyze a complex repairable system＇s corrective maintenance（CM） process.On the basis of building a maintenance process concept model,the modeling method via a stochastic maintenance function block diagram（MFBD） is presented.Testability characteristics are considered in the model and the simulation model can describe multi-indenture multi-echelon（MIME） system corrective maintenance,in which complicated hierarchy and logical relationship between the process are concentrated.Subsequently,a calculating simulation method of mean repair time of complex repairable system is given according to simulation objects status,which changed in the processes of system maintenance influenced by resources queueing,and finally,a simulation application case of complicated repairable system is constructed to illustrate the simulation,and correctness and applicability of the model is confirmed through the sensitivity analysis by ajusting the influenced factors such as testability design parameters.
