Abstract

We can call the envelopment DEA models as radial efficiency measures, because these models optimize all inputs or outputs of a DMU at a certain proportion. Fare and Lovell (1978) introduce a non-radial measure which allows nonproportional reductions in positive inputs or augmentations in positive outputs. Table 4.1 summarizes the non-radial DEA models with respect to the model orientation and frontier type.
