The problem of infeasibility arises in conventional radial super-efficiency data envelopment analysis (DEA) models … under variable returns to scale (VRS). To tackle this issue, a Nerlove–Luenberger (N–L) measure of super-efficiency is … developed based on a directional distance function. Although this N–L super-efficiency model does not suffer infeasibility …

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 …

This paper aims to provide an advanced dynamic efficiency assessment methodology for city performance strategies in … Japan, based on an extended and super-efficient Data Envelopment Analysis (DEA). The use of this novel efficiency …. This new model is able to present a more realistic efficiency improvement projection comprising a dynamic system of target …
