In this paper we discuss about nonzero solution of dual fully fuzzy linear system in form ˜ A ˜X = ˜B ˜X + ˜c. We apply the parametric form of dual fully fuzzy linear system (DFFLS) and propose all manners in four types of them, that based on the elements of ˜ A and ˜B that they can be positive or negative and we discuss on the nonzero solutions of four types of DFFLS. Finally we present numerical example to illustrate our method to solve DFFLS better. guidelines for 11th Iranian Conference On Fuzzy Systems
