Sensitivity analysis of the proportionate change of a subset of outputs or/and inputs in DEA

Sensitivity analysis in data envelopment analysis (DEA) is studied for the case of the proportionate change of a subset of outputs or/and of a subset of inputs of an efficient decision making unit (DMU) according to the Charnes-Cooper-Rhodes (CCR) ratio model. Sufficient conditions for an efficient DMU to preserve its efficiency under the proportionate change of a subset of inputs or/and of outputs are obtained. An illustrative numerical example is provided.
