摘要: 为提高区域轨道交通系统(RRTS)正常运营下的可靠性和故障情况下的弹性,分析区域轨道交通网络(RRTN)的拓扑特性,构建拓扑结构弹性评价模型,实现突发条件下系统弹性的定量评价;提出一种基于系统弹性的结构评价方法,根据节点重要度评价,识别出系统关键节点;应用弹性损失三角形,进行多种故障情况下系统最优恢复策略研究。结果表明:RRTN在Space L 模型下具有无标度网络特性;系统弹性分析结合科普兰评分法,可以提高RRTS节点重要度评价的准确性;最优故障恢复策略从全局角度寻求不同恢复策略下系统弹性的最大值,优化了RRTS结构弹性和系统恢复能力。

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.

Key words: regional rail transit system(RRTS), system resilience, node connectivity, evaluation of node importance, optimal recovery strategy
