Fuzzy linear programming with symmetrical trapezoidal fuzzy coefficients
系数为对称梯形模糊数的模糊线性规划

In dealing with the linear programming with fuzzy coefficients, we propose a linear programming method involving symmetrical trapezoidal fuzzy numbers, and give the corresponding theorems, propositions and algorithms. The efficiency of the method is demonstrated by an example. The proposed method differs from the conventional ones in the fact that the optimal solution can be obtained without transforming it into the classical linear programming. This makes the results more desirable to the decision makers.
