Abstract :

Data Envelopment Analysis is linear programming based procedure that can be used to assess Economic efficiency of decision making units. If data uncertainty prevails where inputs and outputs are assumed to lie in intervals then economic efficiencies also belong to intervals. In the presence of interval data we formulated two pairs of economic efficiency problems under weak and strong optimistic and pessimistic view points. The economic efficiency intervals are shown as nested.
