物流配送及回收混合网络的优化模型

The Optimization Model for Integrated Logistics Network Design of Distribution and Recovery Center

为提高管理物流网络的效率,基于混合整数规划的方法,建立了单产品、单周期、有能力限制的产品配送及回收混合物流网络的双层优化设计模型。双层模型从配送、回收方及客户两方的利益考虑,使得在两方相互协调的情况下最大限度地获得能使两方都满意的选址方案及配送、回收的物流分配。最后,通过具体算例验证了该模型的有效性。

This paper set up a mixed logistics network of distribution and recovery center which improves the logistics management efficiency using bi-level programming. The programming is suitable for the single commodity, the single period, limited capability location problem. Considering the profit of the two parties, logistics center and client, the problem is solved in bi-level pro- gramming. In the bi-level programming, the top and the underside will assort with each other in order to obtain a location project and logistics distribution which is satisfying to the two sides. Finally, an example was presented to demonstrate the validity of the bi-level programming of location problem.
