In this paper, we use the context-dependent method for ranking decision making units (DMUs) with non-discretionary data in data envelopment analysis (DEA). This methodology partitions a set DMUs into the several levels of efficient frontier, then obtains the efficiency of each DMU against of every calculate efficient frontier. We calculate a ranking score for each DMU by this efficiency indexes. Therefore we can rank DMUs by this score. تفاصيل المقالة
