Supplier selection is a problem of selecting the right supplier and finding the right number of units will be purchased from selected supplier. In this thesis, supplier selection problem is defined as multiobjective linear programming. In real situation, decision maker does not have precise and crisp information related to the goals and the constraints. Fuzzy multiobjective linear programming is used to overcome the imprecision of the information. In some cases, the goals and the constraints have different importance to decision maker. To solve this problem we use nonsymmetrical fuzzy decision on fuzzy multiobjective linear programming. Fuzzy multiobjective linear programming is solved by transform it into deterministic singleobjective linear programming, which can be solved using Simplex method. To simplify it, linear programming software such as LINDO, LINGO or �linprog� function in MATLAB can be used. The output is an optimal solution which is also the optimal solution for fuzzy multiobjective linear programming. Firstly, in this paper, we make a function in MATLAB, named PLMOF, which can transform fuzzy multiobjective linear programming into deterministic singleobjective linear programming, and get its optimal solution. At the end of this thesis we present simulations using secondary data.
