Type-2 triangular fuzzy matrices in medical diagnosis

The important and difficult process of medical diagnosis has promoted attempts to model it with the use of type-2 fuzzy numbers. In this paper, the model proposes two types of relations to exist between symptoms and diseases; an occurrence relation and confirmability relation. Also this paper addresses the parametric representation of type-2 triangular fuzzy numbers and arithmetic operations on type-2 triangular fuzzy numbers.
