چکیده:

Data Envelopment Analysis (DEA) evaluates the efficiency of decision making unitswith multiple inputs and outputs. So far, a number of DEA models have beendeveloped: The CCR model, the BCC model and the FDH model are well known asbasic DEA models. In many instance, however, the decision making units can beseparated into different sub-units. In this paper, we study a generalized model forthese DMUs by different sub-units.
