In DEA, there are typically two schemes for measuring efficiency of DMUs; radial and non-radial. Radial models assume … efficiency measure, called slacks-based measure (SBM). In this paper, we point out shortcomings of the SBM and propose 4 variants … of the SBM model. The original SBM model evaluates efficiency of DMUs referring to the furthest frontier point within a …

In DEA, we have two measures of technical efficiency with different characteristics: radial and non-radial. In this …

Traditional DEA models deal with measurements of relative efficiency of DMUs regarding multiple-inputs vs. multiple … needs for inclusion of them in DEA models, we propose a slacks-based network DEA model that can deal with intermediate …

whole terms based on the long-term viewpoint. Dynamic DEA model proposed by Färe and Grosskopf is the first innovative … contribution for such purpose. In this paper we develop their model in the slacks-based measure (SBM) framework, called Dynamic SBM … (DSBM). The SBM model is non-radial and can deal with inputs/outputs individually, contrary to the radial approaches that …

This study introduces a new scheme of data envelopment analysis (DEA) named cost gradient measure (CGM) to evaluate … technical efficiency. In this model, we can obtain more cost conscious technical efficiency than those by other traditional DEA … models such as CCR[7] and slacks-based measure (SBM) [19]. In addition, the CGM can avoid shortcomings of these traditional …
