| 摘 要： | 利用Excel求解线性规划问题时,所得结果并不能判别该问题存在唯一最优解还是无穷多最优解.在Excel对线性规划问题进行灵敏度分析的基础上,结合单纯形法原理和对偶理论,给出了判定所得最优解是唯一最优解还是无穷多最优解的方法.

| 关 键 词： | Excel 无穷多最优解 对偶变量 |

| Abstract: | Whether the linear programming exists alternative or unique optimum solutions can not be distinguished when the Excel is used to solve the linear programming, According to simplex method and duality theory, a method of how to distinguish the alternative or unique solution of the linear programming in the Excel is got by sensitivity analysis. |

| Keywords: | Excel alternative optimum solutions dual variable |
