摘　　要：在分析物流节点定义及其布局内涵的基础上,针对本文所研究的物流节点系统结构特点,构建了多时期、多物流节点、多种类型物流的物流节点系统动态布局优化模型,该模型考虑物流节点建设固定成本、物流处理费用和物流节点的规模经济效益等因素。针对该模型的特点,设计了基于扩展最小费用最大流的混合遗传算法。Based on the analysis of the definition of logistics node and intension of Logistics node spatial layout,the model constructed in this paper presented the character of logistics nodes system,which is consist of the first-class logistics node（logistics park） and second-class logistics nodes（including logistics center and distribution center）.According to the above analysis,a dynamic logistics nodes location model of multi-period,multi-type cargo flow and multiple logistics nodes was given.The optimization model considered the factors including fixed cost for logistics opening,handling cost and economic of scale of different type logistics nodes.An effective algorithm based on the heuristic rules and hybrid genetic algorithm was presented according to the characteristic of optimization problem
