分销网络设计的连续近似模型

对分销网络设计的离散模型和连续近似模型进行比较，指出两者的优缺点及它们之间的互补关系，在已有连续近似模型的基础上，从客户服务因素—周期服务水平—出发，构建了整合库存控制的分销网络设计的连续近似模型，该模型的目标函数不仅包括了分销中心的固定费用、运营费用、运输费用，而且引进了实际中关注的存储费和订货费；该模型在决定分销网络结构的同时，确定了各分销中心的库存策略(订货点和订货量)。最后文章给出了此模型的解法和一个数值例子。

Continuous approximation model of distribution network designing

This paper presents an overview of discrete and continuous approximation models of the distribution network designing, as well as the models' strong points and shortcomings. It is proposed that discrete and continuous modeling approaches complement each other. Based on customer service item-cycle service lever, a new continuous approximation model of distribution network designing that integrates inventory control, and its solution framework are proposed in this paper. Through the model, we can get the solutions of distribution network, the reorder point and order amount of distribution centers' inventory strategies at the same time. At the end of this paper, a numerical example is given.
