Some fuzzy multicriteria methods have recently been developed by using type-2 fuzzy sets. Fuzzy TOPSIS is one of these methods. While these need excessive arithmetic operations with respect to type-1's, they can handle the uncertainty in defining membership functions. We modified Buckley's fuzzy AHP method by using type-2 fuzzy sets.
