Applications of the DEA models show that inadequate results may arise in some cases, two of these inadequacies being: a …) too many efficient units may appear in some DEA models; b) a DEA model may show an inefficient unit from the point of view … concept of a terminal unit is introduced for such units. A method for improving the adequacy of DEA models based on terminal …
