Supply Chain Information Sharing Evaluation Based On Soft Set Theory

With the relationship between supply chain becoming more close, informationsharing among enterprises is particularly important. In order to facilitate the flow ofinformation, Supply chain must be established on information sharing. Supply chaininformation sharing refers to the upstream and downstream companies of supply chainto share their information with each other,in order to achieve the coordination andoptimal efficiency of the entire supply chain. Because of the lack of effective andreliable quantitative evaluation model,it is not easy to determine the extent of thesupply chain information sharing usually.and make the supply chain node enterprisescan’t realize their operating conditions of the supply chain clearly. When the level ofinformation sharing become low,it is difficult to realize and take effective measures,resulting in the increase of costs and decline of competitiveness,the supply chainlosing market advantage gradually. Soft Set Theory is an emerging tool to deal with theproblem of uncertainty. It can overcome the problem of parametric unreasonable whenthe traditional methods of traditional mathematical methods,such as traditionalmathematical probability theory, fuzzy set theory, interval mathematic theory, roughtheoretical, dealing with unreasonable problem.The objects described method of softsets described method is very flexible.In this paper, the soft set theory is applied in theevaluation research of supply chain information sharing.Making up the the limitationsof traditional supply chain information sharing evaluation model considering theintegration information including a variety of quantitative and qualitativeinformation.The main contents and results are as follows:Firstly,this paper review the research status of soft set and supply chaininformation sharing evaluation on the basis of the relevant literature, summarizing outthe features and shortcomings of common evaluation models of supply chaininformation sharing, introduce the concept of soft set. Second,it propose a new supplychain information evaluation index system under the construction principle.Third,itintroduces the definitions of soft set,bijective soft set,significance,dependency、decisionsystem of two bijective soft, and presents a reduction approach of bijective soft setbased on the decision system.Fourth, according to the real value corresponding to theevaluation index of eight kinds supply chain information sharing to cluster analysis,Byquantitative information is transformed into qualitative information to constructbijective soft decision system. Then calculating a parameters reduction of bijective soft set to identify the key factors that affect the supply chain information sharing results,and quantified the significance of each parameter, a new evaluation of the supply chaininformation sharing is obtained,enrich the existing supply chain information sharingevaluation research system.
