On solving fully fuzzy linear programming problems

In this article, we focus on a general model of fuzzy linear programming which all parameters are a kind of fuzzy numbers. As we know, there are a few approach in the literature to solve these problem. Here, we are going to first give a general classification of all fuzzy linear programming models and then investigate fully fuzzy linear programming problems. In particular, we present a new method for solving Fully Fuzzy Linear Programming (FFLP) problems. Although, it has been considered and expanded from many various points of view in more than a decade, but still it is useful to develop new procedures to present better fit into real world problems as much as possible. After introducing FFLP, we propose a new method to solve these kinds of problems. The method is based on the definition of membership function and using the convenient techniques for solving the classical multi-objective programming. We will explore some shortcomings of the exist approaches and then give a new approach to overcome these problems.
