چکیده    As regards of supper efficiency models which increased thediscrimination power of the standard dea models, still infeasibility mayoccure. in literature there exists some models overcome this difficulty.in this paper a new procedure has been mooted in order to remove thisshortcoming in a way that both input savings and output surplus arebeing considered. this procedure deals with nonradial changes for bothinputs and outputs at the same time. the great feature of this model isits simplicity and that correspondence linear counter part can be easilywritten.
