摘要: “新冠肺炎”疫情突发严重危及了人们的生活安全,而物流保障在疫情防控、保民生活、稳定社会方面却起到了重要支撑作用。以保证民生的零售物流配送为背景,本文研究考虑订单释放时间的车辆路径优化问题,以配送完工时间与运输成本的加权之和最小为目标,构建了线性规划模型,并设计了改进的迭代局部搜索求解算法。该算法采用基于多种邻域结构和改进的US算法的局部搜索过程以增强算法的寻优能力,通过引入大路径和最优分割过程获得高质量的初始解和打破机制以增强算法的搜索效率。同时,提出一些性质用于拉格朗日松弛算法,为本文研究问题提供高质量的下界。最后,数值实验部分通过求解标杆算例和文中算例验证了模型和算法的有效性,并对订单释放时间和模型参数进行灵敏度分析,结果表明本文模型和算法能够为零售物流配送的效率提升和成本控制提供有效的决策支持。

Abstract: The epidemic outbreak of“COVID 19” seriously endangers people’s life security, while logistics security plays an important supporting role in epidemic prevention and control, protecting people’s lives and stabilizing society.Based on the background of retail logistics distribution to ensure people's livelihood, the vehicle routing problem considering order release dates is studied, and a linear programming model with the goal of minimizing the weighted sum of delivery completion time and transportation costis constructedand an improved iterative local search solution algorithm is designed.In this algorithm, the local search process based on a variety of neighborhood structures and the improved US algorithm is adopted to enhance the optimization ability of the algorithm, and the large path and the optimal split procedure to obtain high-quality initial solution and the breaking mechanism to enhance the search efficiency of the algorithm are introduced.At the same time, some properties for Lagrange relaxation algorithm are proposed to provide a high quality lower bound for the problem in this paper.Finally, the effectiveness of the model and algorithm by solving the benchmark and the numerical instances are verified in the paper, and sensitivity analysis on the order release dates and model parameters are carried out. The results show that the model and algorithm in this paper can provide effective decision support for the efficiency improvement and cost control of retail logistics distribution.In this research, not only a theoretical basis for enterprises to make efficient decision plans in different periods of operation requirements is provided, but also some enlightening significance to the similar problems with the requirement of time and transportation cost balance in practice is provided.
