中文摘要：	自上世纪90年代，科学技术的进步和经济全球化的发展，使市场转换成买方的市场，客户的需求也向个性化、多样化以及多层次性转变，企业之间的竞争不断加剧。企业的竞争优势的获得已经由传统的对企业内部资源有效的管理，转向对整个供应链的资源的有效管理和整合上，企业与企业的竞争已转化为整个供应链的竞争。而在供应链管理中，一方面，由于组成供应链的成员企业都是以独立的经济体而存在，以利益最大化为目标，从而导致供应链不协调的“双重边际化”或“多重边际化”现象出现；另一方面，企业面临越来越多的不确定性，如信息不对称、供应商或零售商不稳定、外部环境的不确定性和供应链节点企业的风险态度等，也对供应链的管理带来负面的影响。 本文首先在无风险状况下，面对具有双重不确定性的市场环境，对由单一生产商和单一零售商所组成的供应链系统，基于传统的报童问题模型建立了风险中性的生产商和零售商在数量弹性契约约束下的生产决策模型和订货决策模型，并根据模型对生产商和零售商的最优生产决策和最优订货决策进行了分析。然后，通过数值算例分析了数量弹性契约对于供应链协调的贡献和影响。 之后将模型扩展到考虑生产商为风险规避的情况，在模型中引入下方风险对生产商的风险厌恶程度进行描述，并建立了生产商相应的生产决策模型，在此基础上，探讨生产商的最优生产决策，并分析了风险对于生产商的生产决策和零售商的订货决策的影响。文章还对生产商为风险中性和生产商为风险规避型下的相关供应链成员的决策进行了比较。然后，通过数值算例分析了风险对供应链的相关成员企业的决策的影响。 本文最后对前文进行总结，概述了本文的研究结论和创新点，同时指出研究中存在的不足和进一步研究的方向。
英文摘要：	Since the 90s of the 20th century, with the innovation of technology and continuous deepening of global and regional economy, the traditional market has become the buyer’s, and the customer’s demand has also been personalized, diversified and multilevel, which lead to the drastic competition. So, the most of enterprises begin to turn their focus to the entire supply chain management, instead of the management of the enterprise’s internal resources. During the process of supply chain management, the supply chain composed of the independent economic entity who have themselves’ business purpose and decision-making power, so they pursuit to maximize their own interests. Then the phenomenon of “Double marginalization” or “Multiple marginalization” appears, and leads to the incoordination of supply chain. On the other hand, with the continuous changes of environment, enterprises are facing the more and more risks of uncertainty, such as information asymmetry, supplier or retailer unstable, the uncertain external environment and the company’s attitude of risk. Those also bring the incoordination to the supply chain. In this paper, first of all, the research object is the supply chain composing of one manufacturer and a single retailer. Under the risk-free condition and facing the dual uncertainty market environment, based on the traditional “newsvendor problem” and the quantity flexibility contract, we build the model of production decision to manufacturer and ordering decision to retailer. Then, according to those models, we analyze the optimal production decision of supplier and the optimal ordering quantity to retailer. At last, the contribution of the quantity flexibility contract on coordinating the supply chain is proved by numerical analysis. After that, the model mentioned above is extended to the situation in which the manufacturer is considered as the risk aversion. In the model, we introduce the Downside-risk to describe the degree of supplier’s risk aversion, and establish the new model of manufacturer. Then, under the new model, we analyze the supplier’s new production decision again, and the influence from the Downside-risk on the optimal production decision and ordering decision. At the end of the paper, we compare the former decisions under the free-risk condition to the decisions considering the Downside-risk. After this, according to the numerical analysis, we find the influence from the risk. The last chapter summarizes this dissertation, outlining the conclusions and innovations of this research and pointing out some shortcomings and directions that are worthy of being further corrected and studied.
