either of these senses, the efficiency status of a decision making unit (DMU) is classified as either weak or strong. It is … new classification of DMUs in terms of both DEA and Pareto efficiencies. To make this classification, we first demonstrate … single-stage model for each DMU, and (2) it accomplishes the classification of DMUs in both input and output orientations …

In this paper we propose a Pyramidal Classification Algorithm, which together with an appropriate aggregation index … the three classification methods proposed, in order to obtain the classification that best fits the original structure of …
