基于供应中断的多源采购策略研究 摘 要 随着经济全球化的发展，供应链管理也不断地朝着精益化和全球化的方向发展，供应链在时间和空间上同时都得到了延伸，但是其复杂度和脆弱性也随之日益加剧，供应链中断风险也随之加剧。目前供应中断风险管理已经成为一个研究热点,但是关于它的研究还处于摇篮阶段，理论研究不够成熟。在供应链的采购领域，关于单源和多源采购策略的争论喋喋不休，持续了数十年，对二者的优势和不足的定性研究分析也已经相当的丰富，但是对于两种策略如何选择的定量模型较少，而且在供应中断情况下研究两者的选择策略就更少了，本文可以弥补供应链中断风险研究的不足，还能进一步完善供应链管理体系，因此对本课题的研究有着非常重要的理论价值和意义。 本文通过考虑需求是随机的，建立双供应商-单制造商模型，并将双供应商分为供应商同质和不同质两种情况，分别求得最优解，并且以需求服从平均分布为例，进行算例分析，从而验证了模型。通过比较同质和不同质供应商两种情况下的期望收益，得出多源采购策略下选择不同质供应商对企业较为有利的结论。 关键词：多源采购；供应中断；实物期权；最优订货批量 The Research of multiple Source Procurement Strategy Based on Supply Disruption ABSTRACT With the development of global economic, supply chain management trends to lean production and globalization, the supply chain has been extended in both time and space, but meantime its complexity and fragility is raised and the probability of supply chain disruption is also increased. Currently, study on supply chain risk management has become a hot spot, but it is still in a fledgling stage. In the field of supply chain procurement, monoclonal and multiple-source procurement policy debate for decades, the qualitative analysis of advantages and disadvantages of the two also is quite rich, but the two strategies to choose between a quantitative model is less, and even based on the research of supply disruptions, this paper can make up for the shortage of the supply chain disruption risk research, also can further improve the supply chain management system, so the study of this subject has very important theoretical value and significance. This paper proposes the optimal order quality under multiple souring strategies, from the perspective of maximization of revenues, based on the risk of supply disruption. We demonstrate the optimal order quantity and allocation though numerical examples, when the demand is evenly distributed. The results indicate that it is more profitable to select heterogeneous suppliers than homogeneous suppliers under multiple sourcing strategy. Key Words: multiple
