چکیده مقاله :
Many applications and studies are concerns about studying DEA mod-els without explicit inputs or outputs for performance evaluation ofDecision Making Units (DMUs). On basis of what provided in DEAliterature in this paper it has been veri ed that in the mentioned ap-proach convexity assumption has not been properly dealt with. Thus,a modi ed approach has been presented and for clarity, an applicationof the DEA models without inputs and outputs are presented.
