A new method for solving fully fuzzy linear fractional programming with a triangular fuzzy numbers

In this paper, we propose a method of solving the fully fuzzy linear fractional pro-gramming (FFLFP) problems, where all the parameters and variables are triangular fuzzynumbers. In the proposed method, the given FFLFP problem is decomposed into three crisplinear fractional programming (CLFP) problems with bounded variables constraints, threeCLFP problems are solved separately and by using its optimalsolutions, the fuzzy optimalsolution to the given FFLFP problem is obtained. Fuzzy ranking functions and addition ofnonnegative variables were not used and there is no restriction on the elements of coefficientmatrix in the proposed method. Finally, numerical example are used in order to show theefficiency and superiority of the proposed method.
