| Abstract: | For efficiency indexes of decision making units(DMUs) in DEA,the paper gives two theorems to find out them,and presents the sufficient condition on their rank order remaining unchanged after a new DMU is introduced.As the condition is unsatisfied two examples are taken in the end to illuminate the result after a new DMU is introduced. |
