Ranking of ‎E‎fficiency in Context-dependent Data Envelopment Analysis with Non-discretionary Data

In this paper, we use the context-dependent method for ranking decision making units with non- discretionary data in data envelopment analysis . This methodology partitions a set DMUs into the several levels of e cient frontier, then obtains the e ciency of each DMU against of every calculate e cient frontier. We calculate a ranking score for each DMU by this efficiency indexes. Therefore we can rank DMUs by this score. In the end, we use our proposed method in the numerical example.
