| Tiivistelmä: | In most models of Data Envelopment Analysis (DEA), the best performers have the full efficient status denoted by unity (or 100%), and, from experience, the authors know that usually plural Decision Making Units (DMUs) have this "efficient status". To discriminate between these efficient DMUs is an interesting subject. This paper addresses this "super-efficiency" issue by using the slacks-based measure (SBM) of efficiency, which the author proposed in his previous paper. The method differs from the traditional one based on the radial measure, e.g. Andersen and Petersen model, in that the former deals directly with slacks in inputs/outputs, while the latter does not take account of the existence of slacks. |
