Sensitivity and stability analysis in DEA

One of the topics of interests in data envelopment analysis (DEA) is sensitivity and stability analysis of specific decision making unit (DMU), which is under evaluation. In DEA efficient DMUs are of primary importance as they define the efficient frontier. In this paper, we develop a new sensitivity analysis approach for the CCR, BCC and additive models, when variations in the data are considered for a specific efficient DMU and the data for the remaining DMUs are assumed fixed.
