The DEA model to be selected regards the relationship established between input and output, that is, the type of return to scale. In this work, the BCC model was used, which means that the outputs increase or decrease at a different rate than the inputs, respecting the issue regarding the size of the units analyzed. That means that input reductions or increases do not generate changes in the outputs in the same proportion. Figure 1 presents the output-oriented DEA-BCC model.
