A DEMATEL Method of Linguistic Distribution Assessment and Its Application in the Analysis of Key Factors About Sustainable Cycle Partners
Decision-making trial and evaluation laboratory(DEMATEL)methods are used to analyze the relationship between interacting factors and identify key fac-tors.In view of the incomplete judgment and the element of linguistic distribution assessment elements in the direct influence relation matrix,this paper proposes the improved DEMATEL method to deal with linguistic distribution assessments and lin-guistic term sets with different semantics.Firstly,this paper defines the similarity formula of linguistic distribution assessment under the numerical scale,and uses the weighted average operator of linguistic distribution assessment(DTWA)to complete the incomplete elements.Secondly,this paper uses the numerical scale of the lin-guistic term set to numeralize the expert's linguistic distribution assessments.The DEMATEL process is carried out by synthesizing the numerical decision information of all experts to obtain the weight of each factor and the influence relationship be-tween the factors.The factors are divided into two groups:The cause group and the effect group.Finally,the proposed method is applied to a practical case of sustainable cycle partner selection.
