A complete efficiency ranking of decision making units in data envelopment analysis. (English) Zbl 0963.91021

Summary: The efficiency measures provided by DEA can be used for Decision Making Units (DMUs), however, this ranking procedure does not yield relative rankings for those units with 100% efficiency. Andersen and Petersen have proposed a modified efficiency measure for efficient units which can be used for ranking, but this ranking breaks down in some cases, and can be usntable when one of the DMUs has a relatively small value for some of its inputs. This paper proposes an alternative efficiency measure, based on the different optimization problem that removes the difficulties.
