Abstract

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 changeof a subset of inputs or/and of outputs are obtained. An illustrative numerical example is provided.

Keywords

data envelopment analysis; efficiency; proportionate change of a subset of outputs or/and of inputs; sensitivity analysis; linear programming
