【摘要】：在供应链中，配送中心连接着供应商和客户，在两者之间起着重要的桥梁作用，配送中心的位置在供应链物流网络中发挥着重要作用,对物流网络的效率提高也有重要经济影响。供应商管理库存（VMI）是提高供应链效率、降低库存成本的重要方式。文章介绍了国内外配送中心选址的研究动态，分析了目前研究结合库管理决策的选址问题，对配送中心选址的影响因素、综合决策设施选址、产品配送和多产品的库存控制策略进行了研究，从而建立了基于VMI的多产品需求环境下的选址-库存联合决策模型。模型以选址成本、运输成本和库存成本综合最小为目标，同时在一定服务水平上决定配送中心的位置、数量、服务范围及其库存控制参数。该模型属于混合整数规划问题，文中给出了求解该问题的遗传算法求解过程，在VS2008平台上编程并进行仿真求解，通过数值算例测算，，结果表明该算法可以有效地求解该问题；最后在不同服务水平条件下对模型求解，结果表明服务水平对模型选址结果也有一定的影响。
[Abstract]:In the supply chain, the distribution center connects the supplier and the customer, and plays an important role in the bridge between the two. The location of the distribution center plays an important role in the supply chain logistics network. The efficiency of the logistics network also has an important economic impact. VMI (VMI) is an important way to improve supply chain efficiency and reduce inventory cost. This paper introduces the research trends of distribution center location at home and abroad. The influencing factors of distribution center location, the comprehensive decision facility location, the product distribution and the inventory control strategy of multi-product are studied. Thus, a joint site-inventory decision model based on VMI is established. The model aims at minimum location cost, transportation cost and inventory cost, and at the same time determines the location of distribution center at a certain service level. The model belongs to the mixed integer programming problem. The genetic algorithm for solving the problem is given in this paper. The process of solving the problem is programmed and simulated on the VS2008 platform. The results show that the algorithm can solve the problem effectively, and finally the model is solved under different service levels. The results show that the service level also has a certain effect on the model location.
