基于复杂网络的我国西部铁路客运网可靠性研究

随着我国西部铁路网建设的推进,路网特性愈加复杂,为保障网络运行效率及安全,运用复杂网络理论,构建铁路客运复杂网络模型,设计各项拓扑参数,分析网络可靠性。以我国铁路旅客列车时刻表为基础,选取西部地区105个站点,构建我国西部铁路客运复杂网络,采用不同攻击策略对西部铁路客运网进行攻击,分析不同攻击策略下西部铁路客运网可靠性。结果表明:我国西部铁路客运网的基本可靠性较差,受到攻击时网络瘫痪速度较快,服务可靠性较好,但部分节点压力较大,在日常运行中需重点保护,为我国西部铁路客运高效安全运行提供理论参考。

A Study on the Reliability Evaluation of Western China Railway Passenger Transport Network based on Complex Network

With the development of railway network in Western China, the characteristics of railway network become more and more complex. To ensure the operation efficiency of the network, a model of complex network is built with complex network theory, and each topological parameter is designed to evaluate the reliability of the network. Using the date of the passenger train timetable in Western China including 105 stations, a complex network model is built to simulate the attacks on the network under different attack strategies, and the reliability of the network is evaluated accordingly. The results show that the basic reliability of the railway passenger transport network in Western China is poor. When being attacked, the network breaks down quickly, and the service reliability is good. However, some nodes are under great pressure and need to be protected in daily operation. This study provides the theoretical reference for the safe operation of the passenger trains in the west.
