【摘要】：现代企业在经济全球化不断发展的时代背景下纷纷采取供应链管理模式。但是，在追求精益化的过程中，由于受到自然灾害、人为等因素的威胁，供应中断现象的发生变得日益频繁。采购环节处于供应链的源头，受供应中断风险的危害最大，一旦发生供应中断，不仅会影响企业自身的生存和发展，而且还会给供应链下游企业造成巨大损失，甚至会影响整个供应链运行效率的提高。因此，，在供应中断风险下制定一个合理有效的订货策略、保证供应链的正常运行有着很大的现实意义。论文首先介绍了研究背景和意义，总结了国内外关于供应链中断风险管理、供应中断风险下的订货策略等研究现状，阐述了供应中断风险下订货策略相关理论；其次，介绍了A公司的订货现状及存在的问题；再次，以A公司和n家备选供应商组成的二级供应链为研究背景，站在A公司的角度，建立了其在需求确定下不考虑供应中断风险、需求确定下考虑供应中断风险、需求不确定下考虑供应中断风险三种情形下的整数规划模型，通过LINGO11.0软件对供应商数量和订单分配数量进行求解，将结果进行对比分析并得出结论，验证了该研究问题和模型的可行性和现实性；最后，对A公司目前存在的问题提出了进一步改进的措施，完善A公司在供应中断风险下的订货策略。
[Abstract]:Under the background of economic globalization, modern enterprises adopt supply chain management mode one after another. However, in the process of pursuing Lean, supply interruption has become more and more frequent due to the threat of natural disasters and human factors. The procurement link is at the source of the supply chain, and the risk of supply interruption is the most harmful. Once the supply interruption occurs, it will not only affect the survival and development of the enterprise itself, but also cause huge losses to the downstream enterprises of the supply chain. It will even affect the efficiency of the whole supply chain. Therefore, it is of great practical significance to formulate a reasonable and effective ordering strategy under the supply interruption risk to ensure the normal operation of the supply chain. Firstly, this paper introduces the research background and significance, summarizes the domestic and foreign research status of supply chain interruption risk management, supply interruption risk ordering strategy, and expounds the relevant theory of supply interruption risk ordering strategy. Secondly, it introduces the order status and existing problems of A company. Thirdly, taking the secondary supply chain composed of A company an dna lternative suppliers as the research background, from the perspective of A company, this paper establishes that the supply interruption risk is not considered under the demand determination, and the supply interruption risk is considered under the demand determination. The integer programming model considering supply interruption risk under uncertain demand is solved by LINGO11.0 software. The results are compared and analyzed. The feasibility and reality of the model are verified. Finally, further improvement measures are put forward for the problems existing in company A, and the ordering strategy of company A under the risk of supply interruption is improved.
