| Abstract: | This paper introduces projection for vector,and discusses the problem of index sequences of triangle fuzzy numbers,including both interval numbers and triangle fuzzy numbers respectively.Based on the optimal sequence,the ranking of alternatives can be expressed by projection values,and the linear characteristics of projection are proved.This method solves the ranking problems of sequences containing different number types.And the method's practicality and feasibility is proved by example. |
