Abstract

In this paper, we first introduce notion of linguistic intuitionistic fuzzy relations. This notion may be useful in situations when each correspondence of objects is presented as two labels such that the first expresses degree of membership, and the second expresses degree of non-membership as in the intuitionistic fuzzy theory. Sanchez's approach for medical diagnosis is extended using linguistic intuitionistic fuzzy relation.
