In this paper, we point out that their model is feasible when input data are positive but can be infeasible when some of input is zero. Their...

It is well known that super-efficiency data envelopment analysis (DEA) approach can be infeasible under the condition of variable returns to scale (VRS). By extending of the work of Chen (2005), the current study develops a two-stage process for calculating super-efficiency scores regardless...
