摘 要: 提出了适用于功能可靠性仿真分析的一种模型描述方法——Fra Nets( functional reliability analysis Nets) ,介绍了 Fra Nets定义、组成、特点 ,以及在功能可靠性仿真中的建模应用 ,并用实例加以说明。 The functional reliability simulation technique (FRST) is a comprehensive reliability design and analysis technique to conduct analysis according to logic thought of traditional speciality. It is able to analyze systematic reliability and performance based on model and single simulation environment, and to deal with the physical failure and parameter deviation of the system. Also it is able to resolve some reliability problems, such as correlation, multistates, non-coherent of system, which is not easy to be resolved by traditional reliability analysis method. This paper presents a new modeling method FraNets (Functional reliability analysis Nets) about FRST for performance and reliability comprehensive analysis. FraNets's concise definition, composition element and their meanings, operational principle and its feature are introduced, and then some application examples of FraNets are explained. In conclusion,the ability of FraNets is demonstrated with a practical example.
