考虑时效与货损的多产品冷链物流配送中心选址与流量分配仿真

摘要

A mixed integer linear programming model is built to describe multi-product cold chain logistics distribution center location and flow allocation problem,in which,time utility and cargo damage are considered,and total costs of the construction of distribution centers,operation,transportation and cargo damage will be optimized.CPLEX is applied to solve this model and the influence of time utility and cargo damage on cold chain logistics network is analyzed based a real company case.The experiment results validate the effectiveness of the proposed method.%针对多产品冷链物流配送中心选址与流量分配问题,构建了考虑时效和货损的混合整数线性规划模型.以配送中心固定建造费用、运营费用、运输费用、货损成本在内的总成本最小为目标,运用CPLEX求解模型的最优结果.以某企业的运营情况为背景,分析时效性与货损性的变化对于冷链物流网络构建的影响,由此验证了本文所提方法的有效性.
