| 摘 要： | 通过对线性规划可行解的分析,讨论了在线性假设下,改变决策单元数据时DEA DA模型的灵敏度分析问题。利用约束条件方程组基础解向量的性质得出了使数据变化前后的判别分类结果保持不变的条件:数据扰动行向量必须满足所有以约束条件方程组的基础解向量为系数的线性方程组。并且给出了判别函数的一些性质。

| Abstract: | Through the analysis of the feasible solution of the linear programming,the sensitivity analysis of DEA-DA on linear assumption in the errors of sampled observations was discussed. Using the properties of base solution vectors of the linear restriction equations, a condition to maintain the same discriminant result between the sampled observations of changed and unchanged was obtained: the disturbed row vector of sampled observations was satisfied all linear equations whose coefficients were the base solution vectors of linear restriction equations. And some properties of discriminant functions were given. |

| Keywords: | DEA-DA model sampled observation discriminant function the optimal solution of the linear programming |
