The super-efficiency data envelopment analysis model under constant returns to scale does not suffer from the infeasibility problem while the super-efficiency model under the condition of variable returns to scale (VRS) can encounter infeasibility (Seiford and Zhu, 1999). In the presence of negative data Portela et al (2004) show that the VRS assumption is indispensable to the range directional model (RDM).
