【摘要】：在当今全球经济一体化的国际化大环境下，任何有实力的企业都不可能独自完成企业的所有业务，而必须要联合其上下游企业协同完成全部业务过程。企业之间的竞争更多体现在供应链之间的竞争。然而，随着社会发展，供应链管理所面临的不确定性因素在不断地增加，从而引起供应链的不确定是企业所面临的众多挑战之一。因此供应链风险管理是供应链管理中的重要问题，是当今科学研究的热点，具有很强现实意义。本文基于粗糙集理论及模糊综合评价主要通过文献回顾对目前对供应链风险进行思考，并对供应链风险因素识别，供应链风险评估体系的构建进行了深入研究，具有较强的实用价值和参考意义。首先，本文从企业的实际客观出发对选题的背景和研究的意义进行了阐述，并对国内外研究现状进行回顾与总结，指出目前研究的不足和需要改善优化的地方。其次，对目前研究供应链风险和粗糙集的相关理论进行综述。从风险的内涵延伸到供应链风险的内涵与特征以及供应链风险的特征，并对粗糙集理论进行简单介绍，为下文做好理论基础。再次，介绍供应链风险识别的原则与方法，并选取指标构建供应链风险评估指标体系。结合模糊理论和粗糙集理论，确定模型的权重值，构建供应链风险评估模型。最后以河北某企业为例进行实证分析，分析企业目前的供应链状态，，并提出可靠有效的风险防范控制策略，为公司建立完整、科学、全面的供应链风险评估体系提供参考。
[Abstract]:In the international environment of global economic integration today, no strong enterprise can accomplish all its business on its own. However, with the development of society, the uncertainty of supply chain management is increasing. Therefore, supply chain risk management is an important issue in supply chain management. Based on rough set theory and fuzzy comprehensive evaluation, this paper mainly reviews the literature review on the supply chain risk, and the identification of supply chain risk factors, supply chain risk assessment system is deeply studied. It has strong practical value and reference significance. First of all, this paper expounds the background and significance of the topic, reviews and summarizes the current research situation at home and abroad, and points out the shortcomings of the current research and the areas that need to be improved and optimized. This paper summarizes the relevant theories of supply chain risk and rough set. It extends from the connotation of risk to the connotation and characteristics of supply chain risk and the characteristics of supply chain risk, and introduces the rough set theory briefly. Thirdly, it introduces the principles and methods of supply chain risk identification, and selects indicators to construct the supply chain risk assessment index system. Combined with fuzzy theory and rough set theory, the weight of the model is determined. Finally, taking an enterprise in Hebei as an example, the paper analyzes the current supply chain state of the enterprise, and puts forward a reliable and effective risk prevention and control strategy to establish the integrity and science for the company. A comprehensive supply chain risk assessment system provides a reference.
