Preservation of Efficiency and Inefficiency Classification in Data Envelopment Analysis

Preservation of efficiency and inefficiency classification according to the Additive model of Data Envelopment Analysis (DEA) under the simultaneous non-negative perturbations of all data of all Decision Making Units (DMUs) is studied in this paper. Conditions for efficiency preservation of all efficient DMUs and for inefficiency preservation of all inefficient DMUs simultaneously are obtained. An illustrative egzample is provided.
