基于复杂网络的长三角地区高铁网络可靠性分析

Analysis of High-speed Railway Network in Yangtze River Delta Region Based on Complex Network

为研究长三角地区高铁网络可靠性,选取长三角地区94个站点信息,建立长三角高速铁路网络,将该网络按照功能划分为运输网和服务网。根据复杂网络基本原理,采用pajek软件绘制长三角地区高铁网络并进行分析。通过模拟仿真对该网络进行不同方式的攻击。仿真结果表明:长三角地区高铁服务网络可靠性较高,运输网可靠性较差,且无论是服务网络还是运输网络,在受到蓄意攻击下网络瘫痪速度都很快,且对节点攻击的破坏力度强于对边的攻击,该研究结果可为长三角地区高铁线路后期建设决策提供参考。

In order to study the reliability of the high-speed railway network in the Yangtze River Delta,selects 94 stations in the Yangtze River Delta to establish the high-speed railway network,and divides the network into transport network and service network according to the function.According to the basic principle of complex network,pajek software was used to draw and analyze the high-speed railway network in the Yangtze River Delta region,and then the network was attacked in different ways through simulation.Results show that the Yangtze river delta region of the high speed rail service network reliability is higher,the reliability of the network is bad,and whether is the service network or transport network,under the deliberate attacks,the network paralysis is fast,and damage to the node attack strength is stronger than on the edge of the attack,the research results can provide reference for the later construction decision of high-speed railway in Yangtze River Delta.
