【摘要】：随着经济全球化和科学技术的快速发展,导致产品从研发开始的寿命周期不断缩短,以消费者个性化与多样化需求为导向的企业间竞争日益加剧,企业所面临的市场形势越来越严峻。因此,企业通过缔结供应链战略联盟来增强竞争力、巩固市场地位成为必然选择之一。由于供应链各节点企业有着相对的独立性,往往因利益的博弈而造成供应链不能发挥应有作用。因此,研究科学合理的供应链契约来改善和制约节点企业合作关系、促使供应链的有效运行,是供应链管理的重要内容,具有十分重要的理论和实践意义。本文以随机需求的三级供应链为研究对象,研究数量折扣-价格补贴双契约机制下供应链协调问题。本文在阐述研究背景、目的及意义的基础上,综述国内外相关研究现状,分析三级供应链的结构与特点、供应链协调相关理论及常见的供应链契约形式与收益分配手段；在随机市场需求条件下,比较分散无协调控制与集中控制下的供应链收益状况,分析分散无协调决策下系统订购量与收益难以实现最优化；采用数量折扣和价格补贴双契约机制设计供应链协调模型,利用联合契约实现供应链整体目标的最优。并运用博弈理论进行供应链收益分配参数的设计,然后结合层次分析法和遗传算法对模型进行求解；最后通过算例分析,验证模型的合理性和可行性。本论文的目的,旨在通过对随机需求条件下三级供应链协调模型及利益分配的研究,从而找出供应链协调的优化模型和方法,为促进供应链协调管理效率与有序运行提供方法上的借鉴和理论指导。
[Abstract]:With the economic globalization and the rapid development of science and technology, the life cycle of products from the beginning of R & D has been shortened, and the competition between enterprises, which is guided by consumers' individualized and diversified needs, is becoming more and more serious. The market situation faced by enterprises is becoming more and more severe. Therefore, it is an inevitable choice for enterprises to strengthen their competitiveness and consolidate their market position through strategic alliance of supply chain. Because of the relative independence of each node enterprise in the supply chain, the supply chain is often unable to play its due role because of the game of interests. Therefore, it is an important content of supply chain management to study the scientific and reasonable supply chain contract to improve and restrict the cooperative relationship of node enterprises and to promote the effective operation of supply chain, which has very important theoretical and practical significance. In this paper, the supply chain coordination problem under the double contract mechanism of quantity discounting and price subsidy is studied by taking the three-level supply chain with random demand as the research object. Based on the background, purpose and significance of the research, this paper summarizes the current research situation at home and abroad, analyzes the structure and characteristics of three-level supply chain, the relevant theory of supply chain coordination, and the common forms of supply chain contract and the means of income distribution. Under the condition of stochastic market demand, the supply chain income under decentralized uncoordinated control and centralized control is compared, and it is difficult to optimize the system order quantity and income under decentralized uncoordinated decision. The coordination model of supply chain is designed by double contract mechanism of quantity discount and price subsidy, and the overall goal of supply chain is optimized by using joint contract. Then the model is solved by using the analytic hierarchy process (AHP) and genetic algorithm. Finally, the rationality and feasibility of the model are verified by the example analysis. The purpose of this paper is to find out the optimization model and method of supply chain coordination by studying the coordination model and benefit distribution of three-level supply chain under the condition of random demand. In order to promote the efficiency and orderly operation of supply chain coordination management to provide the method of reference and theoretical guidance.
