产品销售物流配送中心布局方法研究

论述了产品销售物流配送中心布局规划的重要性,分析了配送中心布局规划现有数学模型的不足,然后提出了基于经济规模理论的配送中心布局规划方法。在考虑配送中心经济规模的前提下,建立了确立配送中心布局方案的数学模型,模型以总费用最小为规划目标函数,并可利用遍历算法对该模型进行求解。经过实例验证,说明运用经济规模理论在确定配送中心个数的范围之后,该模型能在物流中心位置和路网条件已知的情况下对配送中心的个数、位置和规模进行定量确定,对生产企业在较大范围内规划其销售物流的配送系统有重要的理论价值和实用意义。

Research on the planning of logistics distribution center

Authors discuss the importance of the logistics distribution center allocation plan of product sale,present the shortage of the existing mathematical model of distribution center allocation plan,then,put forward the method of distribution center allocation plan based on the theory of economics scale.Considering economics scale of distribution center,authors establish the mathematical model of determining distribution center location scheme.The model's target function is minimal total expenses,and it can make use of the ergodic method to proceed the model.Through example certification, it proves that after applying economics scale theory to determine the number's range of distribution center,this model can accurately fix to the number, position and scale of the distribution center in terms of the position of logistics center and road network condition which have already been known, and it also has important theoretical value and practical meaning for planning manufacturing enterprise's distribution system in large range.
