摘　　要： 分析了用ＣＰＮ建模、ＧＯ法和动态故障树进行可靠性分析的基本原理，指出了其各自的构造过程，给出２个ＣＰＮ模型、ＧＯ模型和动态故障树模型实例，并在适用对象、描述系统功能、工程适用性、多态性、发现故障隐患、非单调性等方面对这三种方法进行了对比分析。最后给出这三种方法的优点与不足，并指出这三种方法在描述系统时采用功能模块化的思想和遵循系统功能流程的原则是对传统可靠性理论的一个突破。 This paper,first of all,makes an description on fundamental theories of CPN,GO and dynamic FTA,points out their constructing procedure.Secondly,CPN,GO and dynamic FTA models based on two practical examples are given.Based on these models,we make a comparative analysis on CPN,GO and dynamic FTA in the following several repects concerned:description of system function;engineering suitability,system multi state;application scope;system nonmonotony;easiness to pick out system fault/error potentials.Finally, we give out the advantages and disadvantages of these three methods, and point out that it is a breakthrough to the traditional reliability theories that module concept is used to simulate a system and system functional flow process principle.
