摘要:

为提升城市轨道交通的可靠性,提出一种基于区间修复的城市轨道交通故障恢复策略;以网络平均效率度量网络韧性性能函数,按不同折返区段分段处理失效线路,构建以网络韧性损失和恢复总时长最小为目标的城市轨道交通故障恢复模型,设计NSGA-Ⅱ算法求解模型;并以成都地铁网络为例,探讨环线失效和放射线失效2种场景下列车运行交路调整对网络恢复决策及网络恢复性能的影响。结果表明:提出的故障恢复方法能有效避免站点修复完成后仍需长时间等待其他站点修复完成才能接入线网运营的情况,考虑列车运行交路调整恢复方案的韧性损失比不考虑运行交路调整时减少28.3%;是否考虑列车运行交路调整对网络环线线路的故障恢复决策影响较大,对外围放射区域线路的故障恢复决策影响较小。

Abstract:

In order to improve the reliability of urban rail transit, a fault recovery strategy for urban rail transit was proposed. It was carried out based on interval restoration. The paper measured the network resilience performance function in terms of the global efficiency of the network. And the failed lines were segmented by different turnback intervals. Subsequently, an urban rail transit fault recovery model was constructed to minimize network toughness loss and total recovery time. An algorithm was designed to solve the failure recovery model, which was based on the global efficiency of the network. Finally, the fault recovery model was applied to the Chengdu metro network. Then the impact of train operation intersection adjustment on network recovery decision and network recovery performance under loop or radial line failure was discussed. The results show that the fault recovery method is effective. It can avoid the situation that the station is repaired but still needs to wait for other stations to be repaired for normal operation. The resilience loss of the recovery scheme considering train operation crossing adjustment is 28.3% less than that without considering operation crossing adjustment. Whether or not to consider train operation crossing adjustment has an important impact on the fault recovery decision for network loop lines, but has a small impact on the fault recovery decision for lines in the outer radial area.
