利用一种新的模糊数排序准则,将约束条件中含有梯形模糊数的模糊线性规划转化为经典的线性规划,进而求得了原模糊线性规划的最优解.与现有方法相比,该方法运算简便,得到的经典线性规划约束条件个数少,降低了计算量,但最优解的质量没有降低.最后给出了此种方法在实际问题中的应用.
Fuzzy linear programming with trapezoid fuzzy numbers in restricted condition is transformed into classical linear programming by using a new ranking criterion, and an optimal solution is obtained. Besides, compared with the existing methods, the operation of this method is simple, and the method has fewer number of constraints, so the amount of operation reduces with the quality of the optimal solution non-decreasing. At last the application of this method is given.
