A one-model approach to classification and sensitivity analysis in DEA

In this paper we use a simple but very important modification of proposed model by Cooper et al. [Journal of Productivity Analysis 15 (2001) 217-246] for classification and determining stability radius and variations ranges of efficient and inefficient decision making units (DMUs). In the suggested method, the number of problems which are solved, is less than of previous methods. We apply the presented approach for real world data set.
