an integrated super efficiency index based on entropy approach

This paper proposes a novel integrated super efficiency method for ranking decision making units using data envelopment analysis. the integrated method is based on the effect of removing a unit from all possible aggregated units using shannon entropy approach. in contrasted with the classical super efficiency method, we do not face infeasibility in our model. this is due to the fact that we do not alter the efficiency frontier in our model. an application of the proposed models for ranking chinese commercial banks demonstrates the practical relevance and advanced future of our method.
