| 摘 要： | 针对反导系统的可靠性评估问题,给出了反导系统任务可靠性的定义,采用任务剖面描述任务时序逻辑关系,建立了各阶段任务的贝叶斯网络（phase-Bayesian networks,phase-BN）任务可靠性模型,并将其组合为多阶段任务系统贝叶斯网络（phased mission system Bayesian networks,PMS-BN）模型,讨论了PMS-BN模型的求解方法。最后通过算例分析,求得反导系统的可靠性,并与Mark-ov以及故障树模型进行比较,分析了结果的精度与计算复杂度。

| Abstract: | In order to evaluate mission reliability of missile defense system(MDS),the definition of mission reliability for MDS is given.The phase-Bayesian networks(phase-BN) reliability model is built.Then,the phase-BN composes to phased mission system Bayesian networks(PMS-BN) and calculation methods are discussed.The solution accuracy and calculation complexity are analyzed by comparing the solution with Markov model and Fault Tree. |
