- Stratified simplex method for solving fuzzy multi-objective linear programming problem Qiumei Liu(liuqiumei1981163.com) Abstract: The objective of this paper is to deal with a kind of fuzzy multi-objective linear programming(FMOLP)problems involving symmetric trapezoidal fuzzy numbers. Several methods has been proposed in the literature in order to obtain fuzzy efficient solution to FMOLP problem. In this paper, we change the FMOLP problem into the complete stratified fuzzy linear programming problem, then use the stratified simplex method to obtain the fuzzy optimal solution directly without converting them to crisp linear programming problem. We then prove that this fuzzy optimal solution is the fuzzy efficient solution of the original FMOLP problem. A numerical example is given to illustrate the proposed method.
