The objective of this paper is to develop new models to compare cost efficiency of decision making units (DMUs) in all feasible input/output weights. Our focus is to determine cost ranking intervals and cost dominance relations in which the former show the best and the worst cost ranking of a special DMU in comparison with the other ones, and the latter specify the DMUs whose cost efficiencies are dominated by one special DMU. Finally, some new results on relevance of computed cost ranking intervals and cost dominance relations are presented.
