Abstract:

A two‐stage procedure is developed by Lee et al. (2011) [European Journal of Operational Research doi: 10.1016/j.ejor.2011.01.022] to address the infeasibility issue in super‐efficiency data envelopment analysis (DEA) models. We point out that their two‐stage procedure can be solved in a single DEA‐based model.
