两级供应链分销模型的研究

本文探讨了最具代表性的两级供应链的分销模型,在前人研究的基础上通过构建与求解连续近似模型,得出分销中心的数目及其服务区域的面积,并通过模型的解来分析整个系统的成本结构。算例表明,模型的求解结果与事实相符,且将订货费同建设费、运营费、运输费一同考虑更能精确描述系统的成本结构。

Study on Distribution System Model with Two-echelon Supply Chain

This paper discusses the most representative distribution model with two-echelon supply chain.On the basis of previous research,it constructs a continuous approximation model and solves it to get the amount of distribution center and the sizes of their service area.And then it analyzes the cost structure of the whole system through the solution of this model.Examples show that the results of the model solution are consistent with the facts.And considering ordering charges together with construction cost,operating cost and transportation cost,the cost structure of system could be described more accurately.
