A DEA model for units with negative data

Ali Emrouznejad, Abdel L. Anouze, Emmanuel Thanassoulis

Research output: Preprint or Working paper › Working paper

Abstract

In this paper we propose an alternative method for measuring efficiency of Decision making Units, which allows the presence of variables with both negative and positive values. The model is applied to data on the notional effluent processing system to compare the results with recent developed methods; Modified Slacks Based Model as suggested by Sharp et al (2007) and Range Directional Measures developed by Silva Portela et al (2004). A further example explores advantages of using the new model.
