基于时效性的冷链配送中心选址问题

摘要

In this paper, on the basis of a summary of the current research literatures on the location of the agricultural produce distribution centers, we introduced a series of constraints to build the location model of cold-chain distribution centers that fitted with the timeliness characteristics of the agricultural produce and then through an analysis of the overall cost of a three-echelon two-stage cold chain system, built the corresponding hybrid integer nonlinear location model. At the end, we applied the model to a numerical example.%在总结和分析以往农产品配送中心选址相关研究成果的基础上，引入腐坏货损成本、车辆制冷能耗成本及顾客对流通时间的限制，尝试进一步探索符合时效性农产品特点的冷链配送中心选址问题。通过对三级两阶段冷链整体成本进行分析，建立混合整数非线性选址模型，结合算例将其与一般选址模型进行对比分析，验证了兼顾经济性和时效性的选址模型在整体成本上更具优势，而且更符合时效性农产品显著时效性的实际要求。
