摘　　要：地下物流系统是现有货运模式的有益补充,能有效缓解地面交通压力。考虑到车辆路径模型应用于地下物流系统的局限性,引入路线汇集节点。针对需求确定的情况,综合考虑地下通道建设成本、运输成本和车辆运载量限制,构建适用于地下物流系统的车辆路径模型。求解随机生成的案例并探讨关键参数的影响。研究结果表明:改进后模型可使总成本降低13.23%,其中通道建设成本权重的下降能够节约总成本,车辆数和车辆最大运载量的变化对总成本和车辆路径均产生影响。研究结果为地下物流系统的通道建设和车辆路径决策提供了参考依据。The underground logistics system is a beneficial supplement to the existing freight transportation mode and can effectively relieve the traffic pressure on the ground.Considering the limitations of applying the vehicle routing model to the underground logistics system,the route aggregation nodes were introduced.In the case of demand determination,considering construction cost of underground passages,transportation cost and vehicle capacity limitation,a vehicle routing model,which is suitable for underground logistics systems,was constructed.Randomly generated cases were solved and the impact of key parameters was discussed.The results show that the proposed model can reduce the total cost by 13.23%.The reduction in the weight of passages construction cost is able to save the total cost.The changes in the number of vehicles in the system and the maximum capacity of the vehicles will have an impact on both the total cost and the vehicle path.These findings provide a reference for passages construction and vehicle routing decision-making of underground logistics systems in the future.
