摘要
基于复杂网络特性,对香港城市轨道交通网络特征值:节点度、聚集系数、平均最短路径、节点和边介数、连通环进行分析。通过节点介数和节点度值,确定了香港地铁中较重要车站。以全网效能和乘客出行成功率为抗毁性指标,研究网络在随机攻击和选择性攻击下抗毁情况,发现网络在蓄意攻击下表现较弱的抗毁性,并且节点失效比边失效给网络造成的损毁更严重。
Based on the characteristics of the complex network,this paper analyzes the characteristics of the urban rail transit network of Hongkong,namely its nodal degree,aggregation coefficient,average shortest path,node-edge betweenness,and connected ring,etc.Through the node betweenness and node degree value,it determines the more important stations in the Hong Kong subway system.With full network performance and the success rate of passenger travel as the indicators of survivability,it studies the survivability of the system under random attacks and deliberate attacks and finds that the network suffers more damage under deliberate attacks,and node failure is more devastating to the network than edge failure.
