摘要: 针对复杂监控系统规模庞大及关键设备为双机冗余结构的特点,提出以动态故障树(DFT)为基础并结合蒙特卡罗方法对监控系统进行可靠性分析的混合方法。利用DFT建立系统可靠性模型,通过蒙特卡罗仿真算法对模型进行仿真计算,得到系统的可靠性指标。通过对地铁车站级监控系统的可靠性分析,证明了该模型的可行性和算法的有效性。

关键词: 监控系统, 动态故障树, 蒙特卡罗方法, 可靠性分析

Abstract: For dealing with the large scale characteristic of complex monitor system as well as redundant structures of critical components, a hybrid method of reliability analysis for monitor system is presented on basis of dynamic fault tree and in combination with Monte Carlo simulation algorithm. Dynamic Fault Tree(DFT) is used to establish the reliability model of monitor systems. Reliability indices can be obtained by Monte Carlo method, which is used to solve the reliability model. A special reliability analysis case of the subway station-level monitor system is proposed, it demonstrates the feasibility of the model and the effectiveness of the algorithm.

Key words: monitor system, Dynamic Fault Tree(DFT), Monte Carlo method, reliability analysis
