城市轨道交通网络的级联失效研究

应用复杂网络理论,构建城市轨道交通网络的级联失效模型,考虑点和边的混合动态模型,对蓄意破坏和随机失效两种情况进行分析,得出相同边承载能力条件下蓄意破坏对网络的传输效率影响最大,以及不同边承载能力对网络的运输效率具有很大影响,这有助于把握真实网络的动力学特征,对提高整个网络的可靠性具有很重要的意义。

Research on the Cascading Failures of Urban Track Transportation Network

With the help of the theory of complex network,the paper builds a mode of cascading failure of the urban track transportation network,which is a dynamic mixture of points and sides,and analyzes the two situations of sabotages random failures,reaching the conclusion that sabotages have the greatest effect on the transmission efficiency of the network with the bearing capacity of the same side,while the bearing capacity of different sides have great effect on the transmission efficiency,which is helpful for the grasping of the dynamic characteristics of the real network and is of significance for the reliability promotion of the whole network.
