ABSTRACT
Stochastic modeling has come to play an important role in many branches of science and industry. An area of particular interest has been the automatic control of stochastic systems, with consequent emphasis being placed on the analysis of stability in stochastic models. One of the most useful stochastic models that appear frequently in applications is the stochastic differential delay equations. In practice, we need to estimate the parameters of systems. If the parameters are estimated using point estimations, the systems are described precisely and hence the study of the systems becomes relatively easier. On the other hand, if the parameters are estimated using confidence intervals, the systems become stochastic interval equations and the study of such systems is much more complicated.
