考虑级联失效与恢复策略的中欧班列网络恢复研究

Research on the Recovery of the China Railway Express Network Considering Cascading Failures and Recovery Strategies

摘要: 本研究聚焦于中欧班列网络在级联失效情境下的恢复性，系统评估了不同恢复策略对网络恢复效果的影响。鉴于中欧班列网络规模庞大且节点与边的高度依赖性，其在外部冲击或内部故障时易发生级联失效，对网络稳定运行构成重大威胁。为此，本文基于中欧班列拓扑结构构建了恢复性模型，结合仿真分析，探讨了恢复时间步、恢复节点比例与失效节点扩展之间的交互作用。研究结果表明，不同恢复策略在应对特定突发事件时具有显著差异，合理的恢复时机与策略选择可显著提升网络的稳定性和恢复效率。本文为优化恢复策略、提升中欧班列网络在突发事件中的韧性提供了理论支持和实践指导。

Abstract: This study focuses on the resilience of the China Railway Express (CR Express) network under cascading failure scenarios, systematically evaluating the impact of different recovery strategies on network recovery performance. Given the large scale of the CR Express network and the high interdependence between nodes and edges, it is prone to cascading failures during external shocks or internal faults, posing a significant threat to the network's stable operation. To address this, a resilience model based on the CR Express topology was developed, and combined with simulation analysis, the interactions between recovery time steps, the proportion of recovered nodes, and the expansion of failed nodes were explored. The results show that different recovery strategies exhibit significant differences in responding to specific emergencies. Proper timing and strategy selection for recovery can significantly enhance the network’s stability and recovery efficiency. This study provides theoretical support and practical guidance for optimizing recovery strategies and improving the resilience of the CR Express network in the face of emergencies.
