基于复杂网络理论的铁路换乘系统鲁棒性分析

Robustness analysis of railway transer system based on complex network theory

基于赋权二部图和复杂网络理论,构建铁路换乘系统的铁路线路网络模型和铁路站点网络模型,定义了站点节点和线路节点的权重计算方法,并结合节点度和节点权重,设计了铁路换乘网络针对异常攻击的鲁棒性分析方法。最后,分别对铁路线路网络模型和铁路站点网络在随机攻击和蓄意攻击下的可靠性进行了实验分析。实验结果表明,铁路换乘系统对于随机攻击具有较强的鲁棒性,而对于蓄意攻击则表现出极强的脆弱性。

Based on weighted bipartite graph and complex network theory, this paper established the railway line network mod- el and the railway station network model of railway transfer system, defined the weight calculating method of station node and line node, and combining the degree and weight of node, designed a reliability analysis algorithm to study the reliability of rail- way transfer network under unwonted attack. In the end, some experiments were set for researching the reliability of the railway line network and the railway station network under random attack and deliberate attack, the result of the present work implied that the railway transfer system is very robust to random attack, but vulnerable to deliberate attack.
