基于CML的城市地铁网络相继故障分析

分析和掌握城市地铁网络的基本特性，有助于规划和运营管理者对地铁进行运输组织和紧急情况的处理。基于复杂网络理论，采用matlab仿真分析，对城市地铁网络相继故障进行了研究。结果表明：在相继故障扩散过程中蓄意攻击比随机攻击具有较快的传播速度，但在扰动幅度和故障规模关系中呈现出相似的变化趋势，蓄意攻击效果并不明显；多目标随机攻击加快了地铁网络相继故障的扩散进程，但对于最终引起的故障规模则影响不大。

Cascading Failures Analysis of Urban Subway Network Based on CML

To better organize the subway transportation and deal with the emergency situations for the planning and operation managers, basic characteristics of subway network should be analyzed and obtained. Based on complex network theory, subway networks are analyzes in terms of cascading failure through matlab simulation methods. The results indicate that deliberate attack has a faster transmission speed than random attack in the diffusion of cascading failure in the urban subway networks, but presents a similar trend in the relationship in the scale of failure and the perturbation amplitude, the effect of deliberate attack is not obvious; multi-target random attack speed up the process of the diffusion of cascading failure in subway networks, but has little effect on the scale of failure.
