Abstract
Z-numbers are expressed by a restriction function and a reliability function. In the literature, Z-numbers have been extended by intuitionistic fuzzy sets but not by other fuzzy sets. This paper extends Z-numbers by using single valued spherical fuzzy sets. Later, spherical fuzzy Z-numbers are used in the development of Z fuzzy AHP methods. These methods are applied to a supplier selection problem.
