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 …

-environment-economic efficiency strategies, based on an extended Data Envelopment Analysis (DEA) in which distinct countries are regarded as Decision … DEA models use a uniform input reduction or a uniform output increase in their improvement projections. The development of … novel efficiency-improvement solutions based on DEA has greatly progressed in recent years. A recent example is the Distance …
