Résumé: A T-spherical fuzzy (T-SF) graph (T-SFG) structure is a generalization of the spherical fuzzy graphs (SFGs) and other extensions of the fuzzy graphs (FGs). In this paper, we define the strong product, cross product, lexicographic product, modular product, and homomorphic product operations between two T-SFGs and investigate some of their properties. We give examples to make the defined operations more understandable. We also propose a multi-criteria group decision-making (MCGDM) method under the T-SF-environment. Besides, a numerical example is given to show the progress of the proposed method.
