Sensitivity analysis in models of data envelopment analysis
Sensitivity analysis in Data Envelopment Analysis (DEA) is studied in this paper for the Charnes-Cooper-Rhodes (CCR) ratio model and for the additive model. Different cases of additive or proportionate changes of inputs or/and of outputs of an efficient Decision Making Unit (DMU) according to the CCR model or according to the additive model are considered. Sufficient conditions for an efficient DMU to preserve its efficiency after corresponding changes of its inputs or/and outputs are presented for these cases. Similar results for arbitrary (or nonnegative) additive perturbations of data of all DMUs in the additive model are described, too.
