摘要: 物流配送需求的快速增长使得集送货问题的应用越来越广泛。针对配送过程中货物载重影响运输成本的情况,研究考虑载重成本的有时间窗的集送货问题。构建该问题的最小化车辆数量和总运输成本的双目标混合整数规划模型,在该模型中,运输成本为车辆载重量与车辆行驶距离的函数。设计两阶段自适应大邻域搜索算法对其求解,通过设计基于模型特点的多种高效的破坏算子和修复算子,引入模拟退火接受准则避免陷入局部最优解来提高算法性能。测试不同规模及特点的标杆算例,结果表明,所提出的两阶段自适应大邻域搜索算法能够高效求解小规模、中等规模和大规模算例,并分析了货物载重以及不同运量系数对运输成本的影响,为物流企业的集送货车辆路径优化提供参考。

Abstract: The rapid growth of logistics distribution demand makes an increasing wide application of pickup and delivery. A pickup and delivery problem with time windows and weight-related cost is studied, considering that the cargo weight has an effect on the transportation cost in the distribution process. A bi-objective mixed integer programming model of the problem is formulated to minimize the number of vehicles and the total transportation cost, in which the transportation cost is a function of vehicles’ load capacities and travel distances. A two-stage adaptive large neighborhood search algorithm is designed to solve the model, where the performance is improved by designing multiple efficient destroy and repair operators and introducing a simulated annealing strategy to avoid local optimal. Instances with different scales and characteristics are tested, showing that the proposed two-stage adaptive large neighborhood search algorithm can solve small-scale, middle-scale and large-scale instances effectively. Also, the impact of cargo weight and different transport coefficients on transportation cost is analyzed, providing reference for logistics enterprises to optimize the route of pickup and delivery vehicles.

Key words: pickup and delivery problem, weight-related cost, time window, adaptive large neighborhood search algorithm
