ABSTRACT
Analytic hierarchy process (AHP) has been extended by many researchers using ordinary fuzzy sets since the 1980s. Recently, ordinary fuzzy AHP has been extended to intuitionistic fuzzy AHP, hesitant fuzzy AHP, and type-2 fuzzy AHP. In this chapter, we focus on recently developed type-2 fuzzy AHP methods and apply the type-2 fuzzy AHP method developed by us for the wind turbine selection.
