| Abstract: | The fault tree analysis is applied to analyze three choose two railway signal microcomputer interlocking system,and the model of the three choose two is established.The theory of minimum cut sets and its application in accident analysis are described with emphasis on putting forward the importance analysis of the weighted structure in sequence gradation of the bottom events of the fault tree.The weighted structure is used to provide a new method for the system safety analysis. |
