上海轨道交通网络的复杂网络特性及鲁棒性研究

Analysis of characteristics of complex network and robustness in Shanghai metro network

以上海轨道交通网络为研究对象,基于复杂网络理论,采用Space L方法构建上海轨道交通网络拓扑结构模型,通过计算网络的多个特征指标值,实证分析了其复杂网络特性;以网络全局效率相对值作为轨道交通网络鲁棒性的评价指标,研究了上海轨道交通网络的鲁棒性.研究表明:上海轨道交通网络在L空间中是小世界网络和无标度网络;上海轨道交通网络对站点遭遇随机故障的鲁棒性强于站点遭受蓄意攻击时的鲁棒性.

Taking the Shanghai metro network as objective, and based on the complex network theory, topology of Shanghai metro network is made by Space L method; the network characteristics are analyzed by calculating the characteristic indicators. The robustness of Shanghai metro network are analyzed by calculating the relative value of network global efficiency. The results indicate that Shanghai metro network is small-world network and scale-free network in Space L. The robustness of Shanghai metro network under random attacks is better than under malicious attacks.
