摘要

为了减少城市冷链物流配送过程中不必要的浪费和成本,本文构建了一种改进的车辆路径问题的同时送取模型。该模型考虑了配送过程中的实时外部温度,并优化了运输、货物损坏和冷藏的总成本。采用遗传算法求解该模型,确定成本最优的分配路径。最后,对模型的有效性和算法的有效性进行了数值验证。

An Optimization Model for Vehicle Routing in Urban Cold-Chain Logistics
In the present study, we construct an improved vehicle routing problem with simultaneous delivery and pick-up model to reduce unnecessary waste and cost in urban cold-chain logistics distribution. This model considers real-time outside temperature during distribution and optimizes the total cost of transportation, cargo damage and refrigeration. The model is solved using a genetic algorithm to determine the distribution path with the optimal cost. Finally, the validity of the model and the effectiveness of the algorithm are numerically tested.
