摘要: 为保障铁路快捷货运运营面对突发事件时的稳定性,采用复杂网络及鲁棒优化理论,研究铁路快捷货运网络(REFN)拓扑特性及鲁棒性。首先,计算网络特征统计参数,分析REFN拓扑特性;然后,评价REFN中的重要节点,建立基于线路等级、度值、介数的综合评价指标;最后,计算不同攻击方式下的鲁棒性指标,对比分析有无级联失效情况下REFN鲁棒性。结果表明:与传统复杂网络节点重要性评价指标相比,考虑线路等级计算出的重要节点对网络鲁棒性影响更大;REFN在随机攻击下具有鲁棒性,在蓄意攻击下表现出较强的脆弱性,在考虑级联失效的情况下网络的脆弱性更加突出。

Abstract: In order to ensure operation stability of railway express freight transport in the face of emergencies, theories of complex network and robust optimization are used to study topological characteristics and robustness of REFN. Firstly, statistical parameters of network characteristics were calculated and topological characteristics of REFN were analyzed. Then, important nodes were evaluated before a comprehensive evaluation index was established based on route grade, degree value and betweenness. Lastly, robustness evaluation index under different attack modes was calculated and REFN robustness with or without cascading failure was compared and analyzed. The results show that in contrast to traditional evaluation index of node importance for complex networks, important nodes calculated based on route grade have a greater impact on network robustness. REFN is robust under random attacks, but shows greater vulnerability under intentional attacks, and even more prominent vulnerability when there is cascading failure.

Key words: railway express freight network (REFN), robustness, cascading failure, topological characteristics, evaluation index
