Heretofore one of the issues which has not considered in DEA sensitivity analysis is modification in the number of decision making units. In this paper some of DMUs are deleted and the influence of it (deleting one or multiple DMUs) is examined. At first two systems are presented for determining the influence of deleting one or multiple DMUs on efficiency status of other DMUs. Then a model is presented for minimizing the number of deleted DMUs such that an inefficient unit becomes efficient. Finally the presented model and systems are utilized for a set of DMUs and the results are reported.
