DEA : Past Accomplishments and Future Prospects
This paper covers some of the past accomplishments of DEA and its future prospects. It starts with the engineering-science definitions of efficiency and uses the duality theory of linear programming to show how, in DEA, they can be related to the Pareto-Koopmens definitions used in welfare economics. Some of the models that have now been developed for implementing these concepts are then described and properties of these models are examined for weaknesses and strengths along with different measures of distance that may be used to determine their optimal values. Relations between the models are also demonstrated en route to delineating paths for future developments. These include extensions to different objectives such as satisfactory vs. full (or strong) efficiency. They also include extensions from efficiency to effectiveness evaluations of performances as well as extensions to evaluate social-economic performances of countries and other entities where inputs and outputs give way to other categories in which increases and decreases are located in the numerator or denominator of the ratio (=engineering-science) definition of efficiency in a manner analogous to the way output (in the numerator) and input (in the denominator) are usually positioned in the fractional programming form of DEA. Beginnings in each of these extensions are cited and the role of applications in bringing further possibilities to the fore is highlighted
