Ranking efficient DMUs based on ideal and Anti- ideal point in DEA

In most models of DEA, the best performers have efficiency score unity, and, from experience, we know that usually there are plural DMUs which have this ‘‘efficient status’’ To discriminate between these Efficient DMUs the researcher have proposed methods called ranking model. In this paper we proposed a new method based on ideal and anti- ideal point. We compute distance between all DMUs to ideal and anti-ideal point and finally we use an index called the relative closeness (RC) for ranking DMUs.
