(8 صفحه - از 13 تا 20)

The role of non-Archimedean ‏ع‎ in the DEA models has been clarified, so that the associated linear programs can be infeasible (for the multiplier side) and unbounded (for the envelopment side) with an unsuitable choice of ‏.ع‎ This paper shows that the overall assurance interval for € in DEA models is unique by the concept of extreme directions. Also, it presents an assurance value for ‏ع‎ using only simple computations on inputs and outputs of DMUS.
