摘要:

针对速度时变下多越库中心协同的库门分配及车辆路径优化问题,综合考虑多越库中心共同配送、车辆行驶速度时变、客户服务时间窗等因素,以集配货及仓库间转运的车辆派遣成本、车辆能耗成本、库内运输成本以及客户惩罚成本之和最小化为目标,建立优化模型。根据问题特征设计变邻域搜索算法求解,在集货、配货、库门分配阶段进行区间内的邻域搜索,通过插入、交换、2-opt等邻域结构寻优,以提高算法搜索速度、改善求解质量。通过多组算例验证了算法的有效性,并针对越库中心数量、多越库配送模式、车辆行驶速度、车辆类型进行相应的敏感性分析,研究结果表明:(1)考虑多越库中心协同配送得出的车辆调度及库门分配方案能有效降低越库中心运营成本,提高物流配送效率;(2)本文设计的变邻域搜索算法通过区间内邻域搜索增强了算法的寻优能力,提高了求解质量;(3)采用电动车配送比燃油车或混合车队配送节约运输成本,各物流企业应加大对电动车辆的使用,优先考虑派遣电动车进行配送服务。本文的研究结果不仅丰富了越库配送模式下的车辆路径问题研究,也为物流企业科学制订配送方案提供理论依据。

Abstract:

The thesis is about the optimization of time-dependent vehicle routing problem with multiple cross-docks and door assignment, considering collaborative distribution of multiple cross-docks, time-dependent speed and time windows of customers. An optimization model is established to minimize the sum of pick up, delivery and transfer vehicles’ dispatching cost, vehicles’ energy cost, forklifts’ transportation cost and penalty cost on earliness and tardiness. A variable neighborhood search algorithm is designed according to the characteristics of the problem. In order to improve algorithm’s searching speed and solving quality, neighborhood search is simultaneously carried out in the interval of pick up, delivery, door assignment and cross-docking operation process, and the neighborhood structure includes inserting, switching and 2-opt. The validity of the algorithm is verified by multi-group examples. The results show that: (1) Considering the time-dependent vehicle speed and collaborative distribution of multiple cross-docks, the vehicle scheduling and cross-dock door assignment scheme could effectively reduce the operation cost and improve logistics distribution efficiency of urban areas. (2) The neighborhood search within each interval enhances the optimization ability of variable neighborhood search algorithm designed in this paper, improves the solution quality and provides an effective algorithm for solving the cross-dock door assignment and vehicle routing problem optimization. (3) Compared with fuel vehicle delivery and mixed fleet vehicle delivery, electric vehicle delivery could save cost. Therefore, logistics enterprises should increase the use of electric vehicles and give priority to dispatching electric vehicles for delivery services. The research results expand and enrich the research of vehicle routing problem with cross-docking, and provide theoretical basis for logistics enterprises to formulate the decision distribution scheme scientifically.

Key words: multiple cross-docks, dock-door assignment, time-dependent speed, cross-docking transfer, variable search algorithm
