| Abstract: | ATS system is characterized by fault tolerance,redundancy,sequential correlation and so on,but there is no traditional reliability analysis method that can accord with the requirement on the analysis of ATS system. To make up for this deficiency,the thesis introduced the fault tree analysis method in the field of the reliability simulation analysis of ATS system. Meanwhile,by means of the fault tree reduction strategy which combines the Faunet simplified method with the DFLM algorithm,the thesis carried out qualitative analysis and quantitative calculation about the fault tree,and utilized the method into the reliability research of ATS system of Beijing Metro line 2. The experimental results show that with this method,the reliability indicators of ATS system can effectively be calculated and the corresponding results of data analysis can be obtained. |
