Abstract In this paper, we suppose a method for analyzing sensitivity and stability of all the decision making units, while inputs and outputs are interval data. Therefore, for estimating radius of stability of a DMU; firstly, we classify the decision making units then we obtain the radius of stability for each classification. For analyzing the sensitivity(More)

One of the important issues in data envelopment analysis (DEA) is sensitivity analysis. This study discusses about deleting some of the inputs and outputs and investigates the influence of it on efficiency status of Decision Making Units (DMUs). To this end some models are presented for recognizing this influence on efficient DMUs. Model 2 (Model 3) in(More)
