Abstract: In this paper, a new method for the representation of concept in factor space by using type-2 fuzzy sets, and the composition method of states of factors is developed. A general model of multifactorial decision making based on type-2 fuzzy sets is formulated, and the comprehensive evaluation problem based on type-2 fuzzy sets is analyzed. Finally, two applied instances are given to demonstrate the effectiveness of the proposed methods.
