Abstract :
In conventional DEA, measures are classified as either input or output. However, in some real cases there are variables whose status is not known as input or output before assessment. These variable are known as flexible measures. One of the most important economic dimensions for ensuring the success of a company is the efficiency with which it uses its resources. Therefore, centering on Assessment costs and profit of financial institutions is an important issue. Aware of the importance of this subject, we propose the cost and profit efficiency model in presence of flexible measures due to the many application of these variables in real world. The proposed models determine the status of each flexible measure as an input or output statue and simultaneously maximize profit/minimize cost in profit/cost model. In order to evaluate the capability model the proposed model are applied to a real-life data set of 50 U.S. banks.
