The purpose of this study is to utilize a new method for ranking extreme efficient decision
making units (DMUs) based upon the omission of these efficient DMUs from reference set of
inefficient and non-extreme efficient DMUs in data envelopment analysis (DEA) models with constant
and variable returns to scale. In this method, an L2- norm is used and it is believed that it doesn't have
any existing problems of such methods. Finally, two numerical examples for illustration and
comparing the proposed method with other ranking approaches are presented.
