چکیده

Many applications and studies are concerns about studying DEA mod-
els without explicit inputs or outputs for performance evaluation of
Decision Making Units (DMUs). On basis of what provided in DEA
literature 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 application
of the DEA models without inputs and outputs are presented.
