چكيده فارسي :
Using super-efficiency, with regard to ranking efficient units, is increasing in DEA. However, this model has some problems such as the infeasibility. Thus, this article studies infeasibility of the input-based super-efficiency model(because of the zero inputs and outputs), and presents a solution by adding virtual DMUs with mean values. Finally, numerical examples are given to clarify the subject matter.
