Providing a model to determine efficiency and ranking DMUs in DEA

In many cases, may be an input or output is considerable effect in decision making. So, in this paper we propose a two-stage model that the first column of data in each stage is not considered, and the model is provided to solve, and thus the importance of input and output vectors corresponding to each of the units to get decision making units(DMU’s). In the second stage, by using weights of corresponding inputs and outputs from the first stage, the calculated efficiency and ranked based on the new efficiency scores do. To clarify this, the paper continues with a numerical example depended on 20 bank branches in Iran and we compare the obtained rank, with the results of ranking of LJK model.
