A new method for solving fully fuzzy linear Bilevel programming problems

Abstract in this paper, a new method is proposed to find the fuzzy optimal solution of fully fuzzy linear bilevel programming (fflblp) problems by representing all the parameters as triangular fuzzy numbers. in the proposed method, the given fflblp problem is decomposed into three crisp linear programming (clp) problems with bounded variables constraints, the three clp problems are solved separately and by using its optimal solutions, the fuzzy optimal solution to the given fflblp is obtained. the proposed method is easy to understand and to apply for ?nding the fuzzy optimal solution of fflblp occurring in real life situations.
