Research problem DEA uses numerical indicators to describe
inputs, outputs and operational environment Some indicators are dependent on the scale
of operation (volume measures) and some are not (index measures)
These are not systematically separated in DEA literature
The goal of the article is to analyse the assumptions behind the existing DEA models and the requirements set for data.

Idea Formulate axioms in the case of CRS for
the models with non-discretionary factors Interpret the N-D factors - index vs.
volume measures Combine all the approaches in one model Emphasis on the formulation of the
assumptions and their implications Explain differences in results Guide model selection

Results Banker and Morey (1986) - Non-discterionary
inputs or outputs in DEA model VRS allow both volume and index CRS model requires volume measures Minor reformulation allows N-D index
measures Lovell (1994) and Ruggiero (1996) - Restrict
the reference set based on environmental indicators Only index type indicators
