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 and(More)
||||||||||||||||||||||||||||||||-Abstract In many real applications, the data of production processes can't be precisely measured. We develop some fuzzy versions of the classical DEA models (in particular, the CCR model) by using some ranking methods based on the comparison of cuts. Our approaches can be seen as an extension of the DEA methodology. The(More)
