fuzzy decision variable

In this paper a new method is proposed to find the fuzzy optimal solution of fuzzy multi-objective linear programming problems (FMOLPp) with fuzzy right hand side and fuzzy decision variables. Due to the imprecise nature of available resources، determination of a definitive solution to the model seems imposible. Therefore، the proposed model is designed in order to make fuzzy decisions. The model resolves the deficiencies of previous models presented in this field and its main advantage is simplicity. To illustrate the efficiency of the proposed method، it is applied to the problem of allocating orders to suppliers. Due to the nature of the fuzzy solutions obtained from solving the model، the decision maker will be faced with more flexibility in decision making.
