Abstract In this paper, we discuss set operations on type-2 fuzzy sets (including join and meet under minimum=product t-norm), algebraic operations, properties of membership grades of type-2 sets, and type-2 relations and their compositions.

1. Introduction The concept of a type-2 fuzzy set was introduced by Zadeh [30] as an extension of the concept of an ordinary fuzzy set (henceforth called a type-1 fuzzy set). Such sets are fuzzy sets whose membership grades themselves are type-1 fuzzy sets; they are very useful in circumstances where it is di
