利用OERI积分值的模糊数排序准则,将含有梯形模糊系数的模糊线性规划转化为经典的线性规划,进而给出原模糊线性规划问题的最优解.该方法具有约束条件个数少,计算简单的特点,同时还可以考虑决策者的偏好来选择参数,从而使得决策方案具有一定的柔性.
Fuzzy linear programming with trapezoid fuzzy numbers is transformed into classical linear programming by using a new ranking criterion based on OERI integral value, and an optimal solution is obtained. Compared with the existing methods, the operation of this method has fewer number of constraints and simple calculation. In the meantime, decision maker can select the optimal solution by the preference characters, which make the solution to the alternative more flexible.
