| 摘 要： | 为完善基于贝叶斯网络的故障树分析方法,提出了保持贝叶斯网络拓扑结构不变、扩展某些事件节点的状态空间、保持事件节点状态空间不变、调整贝叶斯网络的拓扑结构,两种将存在房形事件的故障树转化为贝叶斯网络的方法.对这两种方法的优劣进行了比较,通过对简化的核电站辅助给水系统的分析,验证了上述方法的正确性.

| Abstract: | In order to consummate fault tree analysis based on Bayesian networks,two methods of mapping fault trees with house events into Bayesian networks are proposed.The first method is to enlarge the state space of some event nodes in order to keep the invariance of the network topological structure.However the second method is to adjust the network topological structure in order to keep the invariance of the state space of event nodes.The comparison between the two methods is carried out.The correctness of the two methods is illustrated by means of a simplified example of the nuclear power plant auxiliary feedwater system. |
