摘　　要：复杂冗余系统的共因失效一直是工程中亟待解决的问题.针对传统共因失效模型的缺点,利用超图概念和矩阵相似度的原理,在充分考虑了不同共同原因冲击耦合问题的基础上,提出了一种新的共因失效模型.该模型从实际统计数据出发,不需要专家分析,可以精确计算出不同共同原因冲击对系统的影响,且在实际应用中更加简单.The common cause failure（CCF） of the complex redundant system is an urgent problem in the project.On the basis of the thorough consideration of the different common cause impacts coupling,this thesis proposes a new model of CCF by using the concept of hypergraph and principle of similarity of matrices,aiming at the defects of the traditional model of CCF.The model is built on the practical statistical data and can accurately calculate the impact of different common cause pinch on system without the experts＇ analysis. This model is simpler in the practical usage.
