Variable weights multifactor decision making based on linguistic factor state values
Deqin Li · Systems Engineering - Theory & Practice · 2014
A new 2-tuplc linguistic decision-making model based on pure linguistic labels is presented by applying the classical 2-tuple fuzzy linguistic representation model and the continuous linguistic model synthetically.Furthermore,two transforming functions between the extended linguistic set and the interval of[0,1]are defined,and the concept of linguistic utility vector of linguistic label is introduced.Later,linguistic variable weight vector and linguistic state variable weight vector are constructed by using utility vector of linguistic label and classical variable weight vector as well as classical state variable weight vector.Simultaneously,the formula for calculating variable weights based on linguistic labels and the variable weights synthesis decision-making models are proposed.Finally,an example of group decision-making is presented.
