Özet:

Nowadays, as financial crisis begin to be faced by many countries, using resources productively has become a very important issue. Thus, sectors with limited resources should operate productively and increase their efficiency. Also, the intense competition within the banking sector force banks to use their resources productively. So, banks should evaluate their performances and know about the banks to follow up being as reference. In this study, 11 banks within the banking sector with total assets value of more than 35 billion have been analyzed using data envelopment analysis which depends on lineer programming optimization. For this purpose, data for 4 input factors (deposits, interest expenses, number of employees and number of branches) and for 3 output factors (net profit, credits and interest revenue) have been collected. Then, using data envelopment analysis, efficiency scores for banks have been computed and improvement targets have been suggested for non-efficient banks
