摘要
为全面分析了解地铁网络抗毁性问题,保障地铁网络安全平稳运行。采用复杂网络级联失效理论对城市地铁网络抗毁性进行研究。以北京地铁网络为例,构建北京地铁网络级联失效模型,通过MATLAB软件实现级联失效模型的仿真运算,对比分析不同节点攻击策略北京地铁网络抗毁性。仿真结果表明:随机攻击策略对地铁网络破坏性相对较小,而面临节点重要度和介数的两种蓄意攻击策略时,地铁网络抗毁性较弱。并进一步为地铁网络建设以及运营管理提供理论支持。
In order to comprehensively analyze and understand the invulnerability of the subway network,the subway network is guaranteed to operate safely and smoothly.The incompatibility of urban metro networks is studied by using complex network cascade failure theory.Taking Beijing subway network as an example,the cascading failure model of Beijing subway network is constructed.The simulation operation of cascading failure model is realized by MATLAB software,and the damage resistance of Beijing subway network with different node attack strategies is compared and analyzed.The simulation results show that the random attack strategy is relatively less destructive to the metro network,and the subway network is weaker when faced with two deliberate attack strategies of node importance and median.And further provide theoretical support for subway network construction and operation management.
