基于复杂网络分析的铁路网技术评价

Railway Network Evaluation Based on Complex Network Analysis

摘要: 铁路交通网是典型的复杂网络，将复杂网络的拓扑性质应用于铁路网规划与评价中可以将铁路网形态、能力直观的展现出来。通过铁路评价模型，将拓扑理论应用到铁路网络技术评价中，能将铁路网技术评价的部分指标有更深刻的理论基础。按照实际铁路网构造了两个简单的复杂网络——中国华北和英国铁路网并主要针对复杂网络拓扑性质加以评价，评价结果与实际基本相符。

Abstract: Railway network is a typical complex one. Applying the topological properties of the complex networks to the planning and evaluation of railway network can show the network’s form and ability visually. Through railway evaluation model, applying the topological theory to the rail network’s technical evaluation can ensure a deeper theoretical basis to some indicators of railway network’s technical evaluation. Two simple complex networks—North China Rail Network and UK Rail Network, were constructed according to the actual railway network. And, when using the to-pological properties to evaluate the complex networks, the evaluation result is basically consistent with the actual index.
