Smirlis }, country = {Greece}, institution={University of Piraeus}, abstract = {The classification and the prediction of efficiencies in Data Envelopment Analysis (DEA) is an important issue, especially in large scale problems or when new units frequently enter the under-assessment set. In this paper, we contribute to the subject by proposing a grid structure based on interval segmentations of the range of values for the inputs and outputs. Such intervals combined, define hyper-rectangles that partition the space of the problem. This structure, exploited by Interval DEA models and a dominance relation, acts as a DEA pre-processor, enabling the classification and prediction of efficiency scores, without applying any DEA models.}, journal = {International Journal of Mathematical, Computational, Physical, Electrical and Computer Engineering}, volume = {12}, number = {6}, year = {2018}, pages = {119 - 123}, ee = {http://waset.org/publications/10009165}, url = {http://waset.org/Publications?p=138}, bibsource = {http://waset.org/Publications}, issn = {eISSN:1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {International Science Index 138, 2018}, }
