【摘要】 随着科学技术的高度发达、信息技术的迅速发展和市场竞争的日益激烈，供应链管理已经成为企业的核心战略竞争资源。供应商管理库存(Vendor Managed Inventory，VMI)产生于二十世纪八十年代，现在已被越来越多的公司成功推行。作为供应链环境下的一种库存模式，VMI将供应链上下游企业的库存管理联系起来，通过供需双方需求预测和库存决策等信息的共享和相互协作，有效抑制了传统库存管理模式下存在的信息不对称、预测偏差大、提前期长、库存成本高等问题，以系统、集成的管理思想进行库存控制，推动整个供应链能够同步高效地运行。论文首先介绍了研究背景及意义，提出供应链管理环境下的供应商管理库存和库存管理的国内外研究情况；其次阐述了库存管理的必要性和传统库存管理存在的问题，提出VMI是缓解牛鞭效应的有效方式；接下来建立了四个涉及线性时变需求、指数时变需求、部分短缺量拖后、变质、有限顾客耐烦期、资金(或费用)时值等因素的VMI模型，拓展了原有模型的应用范围，并通过数值算例确定了计划期内订货商和供应商的最优订购次数，同时对模型中的主要参数进行了灵敏度分析。结果显示，顾客服务水平、变质率、丢单系数、顾客耐烦期长度和贴现率等参数对VMI系统的各项成本均有不同程度的影响，其影响程度和影响趋势为供应链管理库存系统的科学决策提供了有力的理论依据。在论文的最后对整篇文章进行了总结和展望。本论文在前人研究的基础上，建立了更具实用性、可行性、操作性的四个VMI模型，扩充了VMI的理论研究，为供应链管理领域理论和实践的发展做出贡献。更多还原

【Abstract】 With the highly developed science and technology, rapidly developed information technology and greatly changed market competition, supply chain management has become the key strategic competition resource of enterprises. VMI came into being in the 1980s, and is successfully being carried out by more and more companies. As an inventory model under supply chain management, VMI connects the companies in the supply chain and avoids the problems such as asymmetric information, big forecast errors, long lead time and high inventory costs engendered under the traditional management models. The buyers share the forecasting data and information of inventory with the vendors in the VMI model, then by controlling the inventory with systematic and integrated management, the supply chain can work synchronously and efficiently.The thesis firstly introduces the research background and significance of this article, summarizes the research home and abroad on vendor managed inventory under supply chain management; Secondly the thesis elaborates the necessity of inventory management and the problems engendered in the traditional inventory management, proposes that VMI is an effective way to deal with the bullwhip effect. Then four VMI models considering the linear time-varying demand, exponential time-varying demand, partial backlogging, deteriorating items, time-limited free back-orders, time value of costs are constructed, which widen the applying range of the former models. The optimal order times of buyers and a vendor are confirmed in the numerical examples and sensitivity analyses are presented to illustrate the models. The results demonstrate that each main parameter has different sensitivity to the costs of each VMI system, which can provide for the VMI system to make better management decision. At last, the summarization and future directi of the thesis are outlined.Four VMI models with high practicality, feasibility and operation are built based on the studies before. The thesis expands the theory on this field, which makes a great contribution to the development of supply chain management.更多还原
