Abstract

So far, there have been developed several kinds of DEA models, say, CCR, BCC, FDH and so on, for evaluating the relative efficiency of decision making units. This paper suggests a new model called a generalized DEA (GDEA) model, which can treat these existing DEA models in a unified way. Theoretical properties on relationships among these DEA models are given first. Next, the efficiencies for these DEA models are compared and clarified by a numerical example with real data.
