【Abstract】 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.更多还原
