The problem of infeasibility arises in conventional radial super-efficiency data envelopment analysis (DEA) models … developed based on a directional distance function. Although this N–L super-efficiency model does not suffer infeasibility …-efficiency model successfully addresses the infeasibility issues occurring either in conventional VRS models or the N–L super …
