Robustness of efficiency scores in data envelopment analysis with interval scale data

Our paper focuses on a robustness analysis of efficiency scores in the context Data Envelopment Analysis (DEA) assuming interval scale data, as defined A. Dehnokhalaji, P. J. Korhonen, M. Köksalan, N. Nasrabadi and Wallenius, “Efficiency to incorporate data”, European Journal Operational Research 207 (2), 2010, pp. 1116–1121. We first show that definition score used our is well-defined measure according Aparicio Pastor (J. T. Pastor, “A for dealing with closest targets DEA”, Applied Mathematics Computation 219 (17), 2013, 9142–9154.). Next, we characterize how robust are respect improvements deteriorations inputs outputs. illustrate two examples: simple numerical example more complex using real-world data.
