A New TOPSIS with Triangular Fuzzy Number and Uncertain Weight Based on Cosines Similar Degree

Abstract

In order to study the interval multiple attribute decision making problem with triangular fussy number and uncertain weight, this paper presents a new method based on cosines similar degree. The detailed procedure of the proposed algorithm and numerical experiment are given. The proposed algorithm is also compared with an existed algorithm. Compared results show that the proposed algorithm are effective and rational.
