Abstract: After the introduction of fuzzy sets by Zadeh, several researchers were conducted on the generalization of fuzzy sets. The notion of intuitionistic fuzzy sets was introduced by Atanassov as a generalization of the notion of fuzzy sets. An intuitionistic fuzzy set for a given universal set is defined by a degree of membership function and a degree of non-membership function. The notion of ternary polygroup is a generalization of the notion of polygroup in the sense of Comer. In this research, we study the concept of intuitionistic fuzzy ternary subpolygroups of a ternary polygroup.
