【摘要】：随着供应链企业间的关系越来越紧密，企业间的信息共享显得尤为重要，供应链必须建立在信息共享上面，才能促进信息的流通。供应链信息共享是指供应链中的上下游各个企业相互共享自己的信息以期达到协调整个供应链，实现整个供应链效率最优化。由于缺乏有效、可靠的量化评价模型,往往不容易确定供应链信息共享程度。使得供应链节点企业不能清楚认识自己所处的供应链的真实运营状况,在信息共享程度偏低时也很难意识到和采取有效的对策,从而导致供应链整体运营成本升高和竞争能力下降,逐渐丢失市场优势。软集合理论（Soft Set Theory）是一种新兴的处理不确定问题的工具。它可以克服传统传统数学方法传统数学方法概率论，模糊集理论，区间数学理论，粗糙理论处理不确定问题时参数化不合理的缺陷。软集合描述对象的方法非常灵活。本文将软集合理论应用于供应链信息共享评价的研究中，弥补了传统的供应链信息共享评价模型在考虑定量信息和定性信息的多种信息融合的情况下应用的局限。本文的主要研究内容和成果如下：首先，本文在相关文献的基础上对供应链信息共享评价和软集合的研究现状综述，归纳总结出来几种常用的供应链信息共享评价模型的特点和不足，引入了软集合的概念。第二，本文在供应链信息共享评价指标体系构建的原则下，归纳得到一套供应链信息共享评价指标体系。第三，本文介绍了软集合和双射软集合及双射软集合决策系统以及依赖度、重要度的相关定义，并且介绍了一种基于系统重要度的约减方法。第四，根据供应链信息共享方案各指标对应的实数值对8种供应链信息共享方案进行了聚类分析，通过把定量信息转化成了定性信息来构造双射软集合，再通过计算双射软集合的参数约简找出影响供应链信息共享结果的关键因素，并且计算出了每个参数的重要度，把每个参数的重要性量化，得出了一种全新供应链信息共享评价的新方法，丰富了现有的供应链信息共享评价研究体系。
[Abstract]:With the increasingly close relationship between supply chain enterprises, the information sharing among enterprises is particularly important. Supply chain must be based on information sharing in order to promote the flow of information. Supply chain information sharing refers to the upstream and downstream enterprises share their own information with each other in order to coordinate the whole supply chain and realize the optimization of supply chain efficiency. Due to the lack of effective and reliable quantitative evaluation model, it is difficult to determine the degree of information sharing in supply chain. So that the supply chain node enterprises can not clearly understand the real operation of their supply chain, when the degree of information sharing is low, it is difficult to realize and take effective countermeasures. As a result, the overall operating cost and competitive power of the supply chain are increased and the market advantage is gradually lost. Soft set theory (Soft Set Theory) is a new tool for dealing with uncertain problems. It can overcome the defects of the traditional mathematical methods, such as probability theory, fuzzy set theory, interval mathematics theory and rough theory in dealing with uncertain problems. The method of describing objects by soft sets is very flexible. In this paper, the soft set theory is applied to the evaluation of supply chain information sharing, which makes up for the limitation of traditional evaluation model of supply chain information sharing under the condition of considering quantitative and qualitative information fusion. The main contents and achievements of this paper are as follows: firstly, this paper summarizes the research status of supply chain information sharing evaluation and soft set on the basis of relevant literature. The characteristics and shortcomings of several common evaluation models of supply chain information sharing are summarized and the concept of soft set is introduced. Secondly, based on the construction of supply chain information sharing evaluation index system, a set of supply chain information sharing evaluation index system is concluded. Thirdly, this paper introduces the decision system of soft set and bijective soft set and the definition of dependency and importance, and introduces a reduction method based on system importance. Fourthly, according to the real values of each index of the supply chain information sharing scheme, this paper makes cluster analysis of eight supply chain information sharing schemes, and constructs a bijective soft set by transforming quantitative information into qualitative information. Then the key factors that affect the result of information sharing in supply chain are found out by calculating the parameter reduction of double soft set, and the importance degree of each parameter is calculated, and the importance of each parameter is quantified. A new evaluation method of supply chain information sharing is obtained, which enriches the existing research system of supply chain information sharing evaluation.
