چکیده مقاله :
Data Envelopment Analysis (DEA) is a technique that uses all collected observations to measure performance. This method presents no data about how to operate on DMU. The present research attempted to study a unit with all its subunits, if the unit is efficient, it means that all its subunits are efficient too and if it is an inefficient, it shows clearly that which one of the subunits makes inefficiency in order to reach to desired performance by correcting just that submit. Studying the performance by each of these DEA models is time-consuming and long. By using general DEA model (GDEA) we can reach to better speed in evaluation of working with five mentioned DEA methods. The present research attempted to study the unit's performance of general GDEA model in presence of subunits, and a general model illustrated to evaluation of unit performance in presence of decision-making subunits.
