【摘要】：经济全球化的快速推进对企业之间的关系也造成了巨大的影响,企业间日益激烈的竞争.已经成为目前发展.的趋势,而单一地企业之间的竞争.也已经逐渐演变为.供应链与供应链之间的竞争。如何有效地对供应链进行管理.是目前管理者关注的重点,库存管理作为供应链管理中必不可少的一环更是得到了众多学者的重视。集配中心模式是基于传统的分散式库存管理模式发展而来的,集配中心作为一个大型的零部件库存集中点,可以实现库存管理的统一化,但是如何制定合理的库存策略.使得库存成本和客户服务水平达到平衡,吸引更多地供应商加入其中,是目前库存管理中研究的重点。首先,本文从集配中心模式产生的背景入手,分析了研究的意义,并对目前国内外学者对集配中心模式进行的研究成果和进度做了总结分析,指出集配中心模式研究中所存在的还有待深入研究之处,从而得出本文研究内容。然后对文中涉及的一些基础的理论知识做了简单说明,着重介绍了集配中心相关概念、思想等。其次,采用(Q,R)和(R,S)两种库存策略,在充分考虑了供应链中供应商和制造商双方的利益的前提下,以达到利益最大化为目的,对研究的问题做了描述和假设,并建立了相关数学模型。之后利用Arena仿真软件建立集配中心模式下的库存系统仿真模型,分别研究了两种库存策略下,改变库存参数时库存成本和客户服务水平的变化。最后,利用遗传算法对仿真模型作进一步优化,通过Arena内置的VBA事件编写代码,运行仿真模型后将优化前后的结果进行对比,得出优化结果,找出能够使库存成本和客户服务水平达到平衡的最优库存策略,为集配中心模式下库存管理策略的选择和制定提出指导意见。
[Abstract]:The rapid advance of economic globalization also has a great impact on the relationship between enterprises, and increasingly fierce competition among enterprises. Has become the current development. The trend toward a single enterprise is competitive. Has also evolved into. Competition between supply chain and supply chain. How to manage the supply chain effectively. Inventory management, as an indispensable part of supply chain management, has been paid more attention by many scholars. The centralized distribution center model is based on the traditional decentralized inventory management model. As a large component inventory concentration point, the centralized distribution center can realize the unification of inventory management, but how to formulate a reasonable inventory strategy. It is the focus of inventory management to balance inventory cost and customer service level and attract more suppliers. First of all, this paper analyzes the significance of the research from the background of the generation of the distribution center model, and summarizes and analyzes the research results and progress of the current domestic and foreign scholars on the distribution center model. It is pointed out that the research on the pattern of set and distribution center needs to be further studied, and the research content of this paper is obtained. Then some basic theoretical knowledge involved in this paper is briefly explained, and the related concepts and ideas of set distribution center are emphatically introduced. Secondly, two inventory strategies (QR) and (RCS) are used to describe and hypothesize the problems studied, taking full account of the interests of both suppliers and manufacturers in the supply chain, in order to maximize the benefits. The related mathematical models are established. Then the simulation model of inventory system is established by using Arena simulation software, and the changes of inventory cost and customer service level under two inventory strategies are studied respectively. Finally, the simulation model is further optimized by genetic algorithm. After running the simulation model, the results before and after optimization are compared, and the optimization results are obtained. To find out the optimal inventory strategy which can balance inventory cost and customer service level, and provide guidance for the selection and formulation of inventory management strategy under the model of set and distribution center.
