摘要

在简要介绍复杂系统可靠性评估最新进展的基础上，介绍了组合法和状态法。针对这两种方法的不足，提出了一种基于故障树分析(FTA)和贝叶斯网络(BN)的可靠性评估方法。通过应用复杂系统的自由贸易区结果，采用自由贸易区向自由贸易区转换的方法，建立了复杂系统可靠性评估的自由贸易区模型。以某导弹发动机为例，验证了该模型在系统可靠性评估中的有效性和优先性。

Assessment of complex system reliability based on FTA-BN method

On the basis of a brief introduction about the recent progress of reliability assessment of complex systems, combined methods and state methods are introduced. In view of the shortcomings and deficiencies of these two kinds of methods, a reliability assessment method is put forward which based on fault tree analysis (FTA) and Bayesian network (BN). By applying the results of FTA of a complex system and adopting the transforming method of FTA to BN, BN model for reliability assessment of the complex system is established. A missile engine is taken for example and the effectiveness and the priority of the model in reliability assessment of system is verified.
