Emergency decision making is still an important issue for unconventional emergency management. For nonstandardized weight distribution in the data envelopment analysis model, an improved data envelopment analysis model by constructing two decision making units, which have the highest and the lowest efficiency to expand the scope of the efficiency value and to avoid the influence of artificial factors on the decision is proposed. Aiming at choices of routing optimization in emergency logistics,

Finally, the validity of the approach and the applied process of the proposed model are tested by a numerical example with the case of the earthquake emergency in Gansu Province, China. Keywords-the improved data envelopment analysis; multiobjective decision-making; route optimization; emergency logistics I.
