A netting clustering analysis method under intuitionistic fuzzy environment

In this paper, we investigate the technique for clustering objects with intuitionistic fuzzy information. We first propose a formula to derive the intuitionistic fuzzy similarity degree between two intuitionistic fuzzy sets and develop an approach to constructing an intuitionistic fuzzy similarity matrix. Then, we present a netting method to make clustering analysis of intuitionistic fuzzy sets via intuitionistic fuzzy similarity matrix. Two numerical examples are given to illustrate and verify our method. (C) 2011 Published by Elsevier B.V.
