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 ecient frontier, then obtains the eciency of each dmu against of every calculate ecient 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.
