REDISTRIBUTING MULTIPLE INPUTS WITH A PARABOLIC DEA MODEL

Parametric DEA models presume a functional form for the efficiency frontier and are used resource redistribution. Parabolic is particular case of these to redistribute single input in Variable Returns Scale scenarios. In this study, we extend model multiple inputs simultaneously, ensuring that all DMUs will become extreme efficient after redistribution maintaining their outputs. The proposed multi-objective Linear Programming Problem (PPL) which provides optimal solution. To solve model, two approaches used, Weighted Sum Objective Functions Separation Variables. Two numerical examples considering outputs results obtained identical approaches.
