| 摘 要： | 用这种方法，首先求解区间DEA模型中DMU的最高效率值和最低效率值，从而确定DMU的区间效率值，并依此对DMU进行分类。然后，建立一个后区间DEA模型，根据该模型的最优解定义DMU能保持其最高效率值的稳定性的指标，并依据该指标进行区间DEA的鲁棒稳定性分析，为了说明这种方法的应用，给出一个算例。

| Abstract: | A new analysis method of robust stability analysis was proposed for general applications. In this method, the solution of the highest and lowest efficiency scores of each decision making unit (DMU) in an interval data envelopment analysis (DEA) is obtained firstly to determine the interval efficiency score of each DMU and classify DMUs. Then a so-called post-interval DEA model is built. Based on the optimum solution of this model, an index figuring out the stability of maintaining the highest score is introduced. As a result, the analysis of robust stability for interval DEA can be achieved. Finally, to explain the application of this method, an example was given. |
