| Abstract: | Based on the method of seeking minimal cut sets of fault trees by minimal cut sets matrix, non-intersect minimal cut sets matrix is further defined in this paper. Using non-intersect minimal cut sets matrix, a new method of quantitative assessment in fault trees is presented. As a result, all process of both qualitative and quantitative analysis in fault trees is systematically given, using cut sets matrix. The software of computer-aided analysis'is developed and run in many examples.The results show that the software, simple and reliable, is easy to be popularized and used. |
