whole terms based on the long-term viewpoint. Dynamic DEA model proposed by Färe and Grosskopf is the first innovative …

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 … show the generality of CGM that it includes CCR as a special case; and compare the CGM result with those of the other DEA …

In DEA, there are typically two schemes for measuring efficiency of DMUs; radial and non-radial. Radial models assume …

It has been pointed out that DEA scores may be influenced by several external environmental factors, which are … uncontrollable for DMUs. It implies that the DEA efficiency score without data adjustment might be biased and impractical for … measuring genuine management efficiency. Therefore it is essential to eliminate uncontrollable effects from DEA scores and …

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 …
