Determination of Trade-Off, which they are feasible and similar variations on all of Decision Making Units (DMU), is important issue in Data Envelopment Analysis (DEA). In this paper, we select these Trade-Offs based on an external evaluation of DMUs such that the correlation between external evaluation and technical evaluation resulted from DEA model is maximized. In fact, we sift the Trade-Offs and select only those of them that result higher correlation between external and technical evaluation of DMUs. We intruduce a generlized DEA models that it select combination of Trade-Offs for the purpose of maximizing between the two assessments. Finally, we show the result of this model in case study that it returns Human Development Index.
