The current paper proposes a slack‐based version of the Super SBM, which is an alternative super‐efficiency model for the SBM proposed by Tone. Our two‐stage approach provides the same super‐efficiency score as that obtained by the Super SBM model when the evaluated DMU is efficient and yields the same efficiency score as that obtained by the SBM model when the evaluated DMU is inefficient. The projection identified by the Super SBM model may not be strongly Pareto efficient; however, the projection identified from our approach is strongly Pareto efficient.
