程利来商贸公司库存管理策略研究【摘要】 我国乳品行业市场竞争激烈，虽然市场不断扩大，但是全行业中只有不到四分之一的企业赢利。2005年以来，随着牛奶、饲料、包装材料、乳糖成本的不断上涨，乳制品企业所承受的压力更是越来越大。为了扩大市场份额，许多企业在保证一定服务水平的基础上，以低价格作为主要的竞争手段。因此，如何在提供完善服务的基础上降低成本，完善库存管理策略成为企业面临的最紧迫问题。物流管理在企业降低成本的过程中被称为“第三利润源泉”。本文首先总结了该领域主要的研究成果，在此基础上论述了论文的理论研究意义；然后阐述了本文涉及的相关理论。在第三章，我们分析了程利来商贸公司的基本情况以及面临的外部环境；我们重点利用ABC法，对三鹿奶粉产品的物流过程进行了成本分析，找出了影响物流成本较大的、没有附加价值的活动，并进一步通过删除、合并等方法进行优化。研究发现，库存量成为影响奶粉物流过程中的重要因素，因此，在第四章我们构建了奶粉产品的库存模型，通过仿真运行进行成本分析。进而设计了新的库存策略(s ,S)，同样建立了Arena模拟模型，并利用optquest找寻到最优的(s ,S)组合值。 本文通过分析影响奶制品成本的物流中的主要因素，在降低物流成本和总成本具有重要的研究意义和现实意义。【关键词】物流系统；价值增值链分析；库存策略；ARENA 仿真；OptQuest[Abstract] Chinas dairy industry market competition is fierce, although the market continues to expand, but the whole industry is only less than 1/4 of the enterprise profit. Since 2005, with the rising cost of milk, feed, packaging materials, lactose, dairy companies are under pressure to bear more and more. In order to expand the market share, many enterprises to ensure a certain level of service on the basis of low prices as the main means of competition. Therefore, how to reduce the cost and improve the inventory management strategy is the most pressing problem faced by enterprises on the basis of providing perfect service. Logistics management in the process of enterprises to reduce costs is known as the third profit source. At first, this paper summarizes the main research results in this field, and then discusses the theoretical significance of the thesis. In the third chapter, we analyze the process Lilai trading company basic situation and facing the external environment; we focus on the use of ABC method, cost analysis of the logistics process of Sanlu milk powder products, find out the effect of logistics cost greatly, no added value to the activities, and further by removing and merging method was optimized. It is found that inventory is an important factor in the process of milk powder logistics. Therefore, in the fourth chapter, we build a model of milk powder products, and an
