Improved data envelopment analysis models for evaluating interval efficiencies of decision-making units

► We present two perspectives for obtaining bounds of efficiency with crisp data. ► The optimistic view uses the efficiency frontier, giving the best efficiency. ► The pessimistic view uses the inefficient frontier, giving the worst efficiency. ► The efficiency interval presents all possible evaluat...
