系统失效树定量分析的新方法

A NEW METHOD OF QUANTITATIVE ANALYSIS IN FAULT TREES

本文利用最小割集矩阵求系统失效树最小割集方法的基础上,进一步定义了不交化最小割集矩阵,并提出了利用它对系统失效树进行定量评价的新方法,系统地给出了利用割集矩阵对系统失效树进行定性定量分析的全过程,并通过多种实例开发和运行了计算机辅助分析软件。结果表明,运算简便,软件通用可靠。

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.
