Abstract

In this study, hesitant fuzzy graph (HFG) structure and some concepts related to HFGs such as homomorphism, isomorphism, weak isomorphism and co-weak isomorphism are introduced. Also, operations of Cartesian product, direct product, lexicographical product and strong product between two HFGs are defined, and examples are given related these operations. Finally, a decision making algorithm and an application of HFGs in decision making are given.
