Super-Efficiency and Sensitivity Analysis Based on Input-Oriented DEA-R

This paper suggests a method of finding super-efficiency scores and modification of input-oriented models for sensitivity analysis of decision making units. first, by using dea-r (ratio- based dea) models in the input orientation, the models of super- efficiency and also models of super-efficiency modification are sug- gested. second, the worst-case scenarios are considered where the efficiency of the test dmu is deteriorating while the efficiencies of the other dmus are improving. then, by combining these two ideas, a model is suggested which increases the super-efficiency score and modifies the change ranges in order to preserve the per- formance class. in the end, the super-efficiency and change interval of efficient decision making units for 23 branches of zone 1 of the islamic azad university are calculated.
