Abstract |
Based on the analysis of railway accidents and safe operation, a dynamic multi-ring evaluation index (DMEI), whose structure was dynamic and reconfigurable logically, was proposed in the paper. And, Based on the structure of this evaluation index system, an analysis method based on accident chain analysis, which was improved from the order relation analysis method, was proposed in this paper. The improved method can be applied to the safety assessment of railway operation system. Last, by using the safety evaluation method proposed in this paper, the evaluation simulation of railway system operation was done, and then the evaluation results were analyzed and explained in theory. |
