摘　　要：为了有效确定城市轨道交通(URT)网络的失效修复策略,提升URT网络的应急管理水平,考虑站点失效程度、修复资源总量及修复队伍数等因素影响,以最小化URT网络弹性损失为目标,提出了受损URT网络的模型修复策略,构建算法对所建立模型进行求解,获得了相应的模型修复策略。结果表明:与枚举法和遗传算法相比,所提算法具有更高的求解效率,能得到较优的求解结果;与常规修复策略相比,模型修复策略能够最小化URT网络性能损失,以较高的修复效率完成受损URT网络的修复工作;模型修复策略受站点平均失效程度、修复资源总量和修复队伍数影响,URT运营部门可以通过控制站点失效程度、增加修复资源储备及增设修复队伍数等措施来提升URT网络应对突发事件的能力。This paper intends to study the effective repair strategy for a damaged urban rail transit(URT) network and thus enhance its ability to respond to disturbances. By abstracting a URT network as an undirect network and introducing the definition of URT network resilience, we proposed the model repair strategy. The model repair strategy aims at minimizing URT network resilience loss and it was constrained by stations’ damaged level, the amount of repair resources, and the number of repair teams. A new solution algorithm was formulated to solve the model repair strategy. Finally, the damaged Chengdu subway network caused by natural disasters, random failures, and terrorist attacks were repaired by the model repair strategy and conventional repair strategy(random repair strategy, preference repair strategy, and key repair strategy), respectively. The effectiveness of the new solution algorithm, enumeration method, and genetic algorithm was discussed. The results imply that the new solution algorithm has the best solution efficiency and the best result in the three algorithms. Taking the damaged Chengdu subway network caused by natural disasters as an example, the resilience of model repair strategy, random repair strategy, preference repair strategy, and key repair strategy are 0.173, 0.203, 0.227, and 0.211, respectively, and the average repair efficiency of model repair strategy, random repair strategy, preference repair strategy, and key repair strategy are 12.60×10;, 6.45×10;, 5.69×10;and 178.96×10;m;·h;, respectively. It indicates that the model repair strategy can effectively minimize the resilience loss of the URT network and repair the damaged URT network with relatively higher efficiency. The effectiveness of the model repair strategy is affected by stations’ damaged level, the amount of repair resources, and the number of repair teams. To enhance the URT network’s ability to respond to disturbances, the URT operation department can take measures such as reducing stations’ damaged levels, increas
