Data envelopment analysis-A basic glossary

Data Evnelopement Analysis (DEA) is a decision making tool for measuring the efficiencies of a set of decision making units. Along with the rapid developments in the field, the research has spawned a DEA-related jargon. As data envelopment analysis has evolved into a narrow but sophisticated domain of its own, most of the familiar management science terminology needs to be viewed against this background so as to be fully appreciated and assimilated.
