We presented a two-stage method for ranking of decision making units. In the first stage, we evaluated each pair of Decision making units separately by using of a proposed DEA method, and in the second stage, the pairwise evaluation matrix generated by results of first stage is utilized for ranking of units via the Analytical Hierarchical Process (AHP). 1. Introduction Data envelopment analysis (DEA) is a non-parametric method for evaluating relative efficiency in Decision making units (DMUs), which was introduced by Charnes, Cooper and Rhodes in 1978 [1]. While, more than one DMU efficient is evaluated in DEA, then ranking of these DMUs are so important. Up to now many models regarding ranking of these Decision making units in DEA have been presented. ---------------------------- Key Words : Decision Making Units, Data envelopment analysis, Analytic hierarchy process, Ranking. @Ascent Publication: www.ascent-journals.com 233
