Abstract: In the analysis of economic system,we always want to obtain the most production of output for the least input consumption because of the limited resources.In this paper we proposed a new DEA model based on two objective programming in input-output oriented way,this DEA model is capable of maximizing the efficiency of individual units at the same time that total input on consumption is minimized and total output production is maximized.At last we give a new method for solving the model.

Key words: DEA, relative efficiency, decision-making units, efficiency frontier
