中文摘要：
针对多态元件组成的二态系统可靠性定量分析的难点，提出了一种基于贝叶斯网络的分析方法．该方法首先将多态故障树转化成贝叶斯网络，然后利用该网络计算各事件发生概率和元件重要度．同时利用该贝叶斯网络还可以得到其他一些有意义的结果，可用于系统故障诊断和实时监控．通过一个供电系统实例说明了该方法的有效性．
英文摘要：
According to the difficulty of quantitative reliability analysis for binary-state system with multi-state components, a new method based on Bayesian networks is proposed. Multi-state fault tree was converted into Bayesian networks firstly, then the probability of each event and the importance of each component were calculated. And additional information used for failure diagnosis and realtime monitoring was obtained at the same time. The correctness of this method was validated through an example of power supply system.
