Further approach to the sensitivity analysis of Data Envelopment Analysis and its application

One model of DEA (data envelopment data) sensitivity analysis is presented in this paper. Using this model, we developed the sufficient and necessary conditions to keep the classification of being efficient or inefficient when only one Decision Making Unit changes. In the last section, an empiric example for measuring competitiveness performance of innovative firms is offered to verify the result, Thus, the proposed method is proved feasible and valid.
