【摘要】 在竞争日益激烈的今天,科技的进步和消费者需求的个性化发展,导致竞争模式也发生了改变,速度已成为当今市场上最有力的竞争武器,随着客户需求的更加多变和对时间敏感性的进一步增强,必将要求供应链企业提供更快的响应能力和更高的内部协调能力。因此,从缩短交货期的角度来研究供应链企业相关交货决策以及协调运作问题,对于增强企业竞争力,提高企业收益以及优化各节点企业和整个供应链的运营成本都具有十分重要的理论价值和现实意义。本文分析了供应链运作中交货期压缩相关的问题,研究了缩短交货期的方法及其在供应链运作中的作用,在此基础上从两种不同的角度研究了面向缩短交货期的相关决策模型:基于价格补偿的交货期相关定价模型和基于新增费用分担的交货期相关决策模型。第一个模型从定义供应链企业与客户对交货期要求的估计概率入手,在时间敏感需求的假定下,以单位时间预期收益最大化为目标,构建了供应链企业基于价格补偿的交货期相关定价模型,然后对模型的最优性进行分析,并给出了相应的决策策略。第二个模型以一个供应商和一个零售商组成供应链系统为研究对象,从介绍下游零售商控制交货期决策权并完全承担缩短交货期费用的决策模型着手,以单位时间内企业订货成本优化为目标,建立了供应商先公布交货期零售商再决定订货批量,缩短交货期的新增费用由上下游双方按一定比例共同分担的决策模型,并通过解析方法和数值算例对两种决策模型下最优决策进行了分析和比较。更多还原

【Abstract】 In the environment of intensifying competition recently, the development of technology and individual customers’requirement leads to the great change of competition pattern which makes speed to be the most powerful advantage in the competition market. With an increase of demand character in variability and time sensitive, supply chain firms are compelled to enhance their capability of quick response and inter-coordination. So in order to improve the competitive capability and increase the revenue for supply chain firms, it makes important theoretical value and actual significance to study the decision of delivery and coordination from the aspect of shortening delivery time.This thesis analyzed the relative issues about delivery time compression in supply chain. The techniques to shorten delivery time and the impact of delivery time compression were discussed, based on which two decision models oriented to shorten delivery time were built from different aspect. At first a premium-based model of lead time-contingent pricing was introduced with defining different estimated probabilities of requirement for lead time between customers and supply chain firms. It was under the assumption of time-sensitive demand with the objection of maximizing the expected profit. In the following the existence of the optimal solution was analyzed and the optimal decision-making strategies were advanced. The second model was based on a supply chain consists of a supplier and a retailer. After the introduction of decision model in which retailer takes charge of the delivery decision and delivery time crashing cost, a new model in which retailer decides order quantity after supplier declares delivery time and delivery time crashing cost are sharing in certain proportion by both of them was built to optimize the ordering cost in unit time. And then, the optimal decisions in two models has been analyzed and compared through analytical method and numerical example.更多还原
