【摘要】 故障树分析技术 ,因其在复杂系统可靠性的定性、定量研究中所表现出的优势而被广泛应用。但是 ,一般情况下的故障树分析都是事先假定元部件具有相互独立 ,确定分布的状态下使用 ,而在现实中 ,往往会出现非二态的系统失效模式。因此 ,对非二态情况的故障树的研究已成为当前的重要课题更多还原

【Abstract】 Fault Tree Analysis(FTA) is widely used for its desirable quality which apply for qualitative and quantitative research of complex system.In general,this technique is used in the condition which is supposed that components have dependent and definite distribution.However,in fact,no-binary state fault pattern often appear in variable systems.The research of mulistate fault tree analysis become an important subject at present.更多还原
