Envelopment form

A DEA model formulation involving the concept of a composite unit. The term ‘envelopment’ stresses the fact that a composite unit is a combination of efficient units enveloping an inefficient unit.

Efficiency score

Efficiency is measured on a scale of 0 to 1, where a value of I indicates the unit is relatively efficient, and a value less than 1 indicates the unit is inefficient. The efficiency score of a unit will vary according to the factors and DMUs included in the analysis. In the early days of …

Efficiency/Productive efficiency

A measure of a unit’s ability to produce outputs from its set of inputs. Since the efficiency of a given DMU is measured with respect to other DMUs in the field, the obtained efficiency is always relative. From the standpoint of the efficiency frontier, an enveloped unit’s efficiency is related to its radial distance from …
