Integrating SBM model and Super-SBM model: a one-model approach

Abstract

The computation of the slacks-based measure (SBM) super-efficiency requires two-stage computation. Moreover, the projection of the slacks-based measure super-efficiency (Super-SBM) might not be Paretoefficient. The super-efficiency might be overestimated by Super-SBM. In the current paper, we will propose an integrated model which not only integrates SBM and Super-SBM but also identifies the Paretoefficient projection and provides a super-efficiency score that is not overestimated. The integrated model will be shown to be feasible and bounded under constant returns to scale (CRS) and variable returns to scale (VRS).(c) 2022 Elsevier Ltd. All rights reserved.
