  abstract = {This paper deals with a new technique for order reduction of higher order discrete uncertain system into lower order discrete time interval system. Using modified Routh Approximation and Affine Arithmetic developed to obtained numerator and denominator of reduced order model. The numerator and denominator of reduced order model is evaluated using modified $\delta$- and $gamma$-table respectively. Which is calculated based on Dolgin {\&} Zehab's concepts [3]. For understanding the effectiveness of the proposed method, it has been applied on two standard numerical examples, it is also found that the proposed method gives less integral square error and better approximation to the original higher order system.},
