Data envelopment analysis (DEA) is a non-parametric method for
analysing the performance of a set of decision-making units (DMUs).
Computing the efficiency scores and ranking each organisation are two
important parts of analysing performance. A large number of DEA models have
been proposed for ranking DMUs, but most of them are unable to rank
non-extreme efficient units. In this paper, a method is proposed based on super
efficiency approach for ranking all DMUs, including extreme efficient,
non-extreme efficient and inefficient units. Then, the suggested method is
applied for ranking DMUs in which undesirable outputs are also produced in
the production process. Finally, numerical examples are provided to illustrate
the proposed approach.
