【摘要】 90年代,由于经济全球化,需求的个性化与多变性,市场竞争已转变为基于时间的竞争,快速反应正成为供应链竞争的焦点。其核心思想就是缩短反应需求的提前期。有效地缩短提前期,可以降低安全库存水平,节约库存投资,提高客户服务水平,并快速响应生产计划的变化,同时也能很好地满足供应链时间竞争的要求。在另一个方面,供应链已由以产品为中心的推式管理模式转变为以顾客为中心的拉式管理模式。面对复杂多变的需求,制造商、供应商和客户必须进行合作,从供应链的角度进行决策和管理,市场竞争由企业和企业之间的竞争发展为供应链与供应链之间的竞争。因此对供应链进行整体优化具有重要意义。论文首先分析了提前期的相关理论,发现提前期主要是由几个独立的要素组成,然而各个要素对提前期的影响是不相同的,因此应用了灰色关联方法来分析提前期的构成要素,以确定哪些构成要素对提前期的影响较大,那些构成要素对提前期的影响较小,从而确定出哪些构成要素是提前期管理的焦点,压缩提前期的重点。提前期的要素理论是可控提前期的基础,论文紧接着利用可控提前期的相关理论,建立较为简单的一个供应商对多零售商的供应链优化模型以及多个供应商对多个零售商的供应链优化模型,并进行算例分析,得到的分析结果与前面学者研究的理论相符,缩短提前期可以降低库存水平,节约供应链成本。更多还原

【Abstract】 Since 1990s, as a result of globalization, the individual and various demands exist the same time which makes market be updated by competition of time. Quick response which means reduce the lead time is the core competition of supply chain. Shorten lead time could reduce safe stock, decrease inventory, raise the customer service level, and responses to the change of product plan.In another aspect, supply chain has transformed from pushing management for taking product as the center to pulling management for taking customer as the center. And now the competition in the market inclines to base on the whole supply chain rather than the only one manufacturer or retailer. Therefore it has great significance to optimize the supply chain.After studying the lead-time related theories, we find that the lead time is composed by several independent integrants. However ,to the lead-time, each integrant does not affect the same, so the gray connection method is used to analysis the integrant of lead time, value the significance of these integrants, and then find out the key point of lead time management.Then the thesis establishes optimization model composed by one supplier to multi-retailers as well as multi-suppliers to multi-retailers based on the controllable lead-time theory. By making a numerical study on the established model, the thesis concludes that shorten lead time could reduce stock and save cost according to researches of other scholars.更多还原
