摘要
针对突发事件造成的节点失效会严重影响地铁运营的效率这一问题,提出了一套基于复杂网络理论的地铁线网脆弱性分析方法。以武汉市现阶段地铁线网为例,采用Pajek构建了涵盖58个站点,57条连接边的当前城市地铁线网拓扑结构图,系统分析了随机攻击和蓄意攻击模式下城市地铁网络的静态与动态脆弱性水平。结果表明:累计节点蓄意攻击对地铁线网破坏性最大,随机攻击次之,单个节点蓄意攻击最小,度大节点为线网中的脆弱点。
Aiming at the problem that node failure caused by the emergencies will seriously affect the efficiency of the subway operations, to solve the problem, an analysis method was proposesed to analyze the vulnerability of subway network based on complex network theory. By taking current Wuhan subway network for example, by used of Pajek tool, a topological struc- ture of the current city subway network was established ,which covered 58 stations and 57 connecting edges to systematically analyze the static and dynamic vulnerability levels of urban subway network in case of facing random attack and purposeful attack . The results show the successive purposeful attacks on nodes will cause most damages to railway network, random attacks will cause secondary damages and purposeful attack on single node point will cause minimum damage to the railway network. The node point of bigger degree is the vulnerable point in the line network.
