冷链物流配送中心选址的多目标优化模型

针对冷链物流所配送物品易腐坏的特性,综合考虑了物流总成本和物流服务可靠度,建立了冷链物流配送中心选址多目标规划模型。通过主要目标法将此模型转化为单目标优化模型,并运用lingo软件对优化模型进行验证,最后通过实例计算,证明了该模型在冷链物流配送中心选址问题中的可行性和通用性。

A Multi-objective Optimization Model for the Cold Chain Distribution Center Location Problem

In view of the perishable nature of the goods in cold chain distribution,the paper considers comprehensively the total logistics cost and logistics service reliability and establishes a multi-objective optimization model for the cold chain distribution center lcoation problem.Using primary objective method,the paper converts the model into a single-objective model and tests it using software LINGO.Finally,in a numerical example,it proves the feasibility and applicability of the model in the location problem of cold chain distribution centers.
