摘要
多阶段任务系统(PMS)若考虑单元可修则难以采用传统方法评估其可靠性,根据蒙特卡洛仿真理论及离散事件仿真方法提出可修PMS的可靠性建模思路,并利用仿真平台ExtendSim建立仿真模型,对每个单元只使用一个ShutDown模块模拟其状态,解决单元跨阶段状态依赖的问题,最后以一个马尔科夫链可解的可修PMS为例,证明了模型的正确性。建立的模型可以使用任意的故障时间分布和修理时间分布,具有适用性强和建模难度低的优点。
Taking account of repairable units, it is difficult to evaluate the reliability of Phased-Mission System（PMS）. The repairable PMS reliability modeling solution was given based on Monte Carlo simulation and discrete event simulation. The simulation model was built using ExtendSim simulation platform. The problem of units state consistency between phases was solved by simulating the state of one unit with one ShutDown module. Finally ,taking a Markov solvable repairable PMS for example,the comparison proved the correctness of the model. The breakdown interval and repair time of units could be subjected to arbitrary distributions, which makes the model has the features of strong suitability and easy-to-build.
