solving fully fuzzy linear programming problems with unrestricted variables

Abstract

In the past few years, a growing interest has been shown in fuzzy linear programming and currently there are several methods for solving FFLP. However, due to the limitation of these methods, they cannot be applied for solving fully fuzzy linear programming (FFLP) with unrestricted fuzzy coefficients and fuzzy variables. In this paper a new efficient method for FFLP has been proposed, in order to obtain the fuzzy optimal solution with unrestricted variables and parameters. To show the efficiency of the proposed method a numerical example have been illustrated.
