On clustering approach to intuitionistic fuzzy sets
Qi Chen · Kongzhi yu juece · 2007
To investigate the problems of clustering intuitionistic fuzzy sets,the concept of intuitionistic fuzzy similarity degree is defined,and intuitionistic fuzzy similarity matrix and intuitionistic fuzzy equivalence matrix are constructed.A compound operational law of intuitionistic fuzzy similarity matrix is defined and an approach to transforming the intuitionistic fuzzy similarity matrices into the intuitionistic fuzzy equivalence matrices is given.Moreover,λ-cutting matrices of the intuitionistic fuzzy similarity matrix and intuitionistic fuzzy equivalence matrix are given,and then an approach to clustering intuitionistic fuzzy sets is proposed.Finally,a numerical example is given to illustrate and analyze the proposed approach.
