Research on the Reliability Modeling and Analysis Method of Phased-Mission System Based on GO Method

A reliability modeling and analysis method is proposed in this paper based on Goal-oriented(GO) methodology for the Phased-Mission systems. Firstly, the Phased-Mission system is analyzed, and the theory and steps of the reliability modeling and analysis method of GO method for the Phased-Mission system are given. Then, taking a Phased-Mission nuclear power plant as an example, the GO method proposed in this paper is used for quantitative calculation and qualitative analysis. Finally, by comparing the results with the Fault Tree method and Monte Carlo simulation method, the feasibility and correctness of GO method for reliability modeling and analysis of Phased-Mission system are proved.
