Tendo em consideração que as organizações estão cada vez mais inseridas num ambiente hipercompetitivo, a avaliação de desempenho tem assumido um papel de grande importância nas mesmas pois, permite não só avaliar a empresa em si, como compará-la às suas concorrentes e, consequentemente, aumentar a eficiência e a produtividade das mesmas de forma a superar a concorrência. Dado que as organizações têm distintos mecanismos de avaliação, é necessário usar uma ferramenta que seja transversal a todas as organizações. Assim sendo, a metodologia DEA é a mais utilizada nestas situações pois, permite combinar múltiplos inputs para produzir múltiplos outputs, usualmente designadas por DMUs (Decision Making Units). Os modelos tradicionais da DEA identificam muitas DMUs como eficientes e, por forma a estabelecer um ranking das mesmas, recorrem-se a vários modelos. Este trabalho tem como objeto de estudo os modelos de super-eficiência e os problemas de inadmissibilidade que deles advém.
Considering that organizations are increasingly inserted in a hypercompetitive environment, the performance evaluation has assumed a very important role in them, since it allows not only to evaluate the company itself, but also to compare it with its competitors and, consequently, increase their efficiency and productive to overcome competition. Given that organizations have different evaluation mechanisms, it’s necessary to use a tool that is transversal to all organizations. Therefore, the Data Envelopment Analysis (DEA) methodology is the most used in these situations because it allows to combine multiple inputs to produce multiple outputs, usually referred to as Decision Making Units (DMUs). The traditional DEA Models identify many DMUs as efficient and, to establish a ranking of them, several models are used. This work has as object of study the models of super-efficiency and the problems of inadmissibility that come from them.
