Abstract
This paper proposes a GO method by taking into consideration the typical characteristics. Then, taking a hoisting mechanism as an example, its steady state availability analysis and qualitative analysis are conducted based on this paper's GO method. In order to illustrate the advantages, reasonability, and feasibility of GO method, the results calculated by GO method are compared with the result of FTA, and the result of MCS. The analysis process of example by using GO method also shows its advantages in establishing reliability model and conducting reliability analysis for complex Phased-Mission Nuclear Power Equipment. All in all, this study not only widens the application of GO methodology; but also provides a new approach for reliability analysis of PMNPE by taking into consideration the typical characteristics.
