基于复杂网络的西北地区铁路换乘网连通可靠性分析

Connectivity Reliability Analysis of Railway Transfer Network in Northwest China based on Complex Network Theory

基于复杂网络理论,对西北地区铁路换乘网使用节点的度分布、累计度分布、平均最短距离、聚集系数和介数等网络静态几何量进行分析。通过案例的研究发现,如果能够通过迂回模式抵达目的地,蓄意攻击对西北铁路换乘网络效率的影响很小。经过比较,乌鲁木齐南站和西安站是整个网络中最脆弱的关键点。

Based on complex network theory, this paper analyzes static geometric quantities of railway transfer network in Northwest China from aspects including degree distribution, cumulative degree distribution, average shortest distance, aggregation coefficient and betweenness of the nodes. An example study shows that if the destination can be reached in a roundabout way, the influence of intentional attack on the efficiency of railway transfer network in the northwest area is very small. By comparison, Urumqi Station and Xi＇an Station are the most vulnerable key points in the transfer network.
