| Abstract: | In order to improve reliability under normal operation and resilience under failures of RRTS,topological characteristics of regional rail transit network(RRTN)were analyzed and a quantitative evaluation model for resilience of topological structure was proposed to achieve system resilience evaluation under failures.A structure evaluation method based on system resilience was proposed,and key nodes were identified based on the node importance evaluation.The resilience loss triangle was applied to find system’s optimal recovery strategy under various failures.The results show that RRTN has characteristics of typical scale-free networks under Space L model.The system resilience analysis combined with Copeland scoring method improves accuracy of node importance evaluation.Optimal fault recovery strategy seeks the maximum value of system resilience under different recovery strategies from global perspective and optimizes structural resilience and recovery capabilities of RRTS. |
