Abstract :
The paper deals with an approach to applications of e-approximate representation of type-2 fuzzy sets using triangulated irregular network (TIN). Geometric algorithms are designed for operations of type-2 fuzzy sets without using manner of upper or lower surfaces. Operations involving meet under minimum, join under minimum, negation, inference process of type-2 fuzzy sets are presented as applications of geometric representation to operations of type-2 fuzzy sets.
