Evaluation of Steady State Probabilities of the • / G / ∞ Queuing System for Different Input Flow Models

Five input flow models are considered whose structures are considerably more complicated than a Poisson structure and in which steady state probabilities of the •/ G / ∞ queuing system can be found in explicit form (the Poisson distribution). For these models, a combination of the Poisson distribution (the analytical part) and statistical simulation (the statistical part) allows one to evaluate steady state probabilities by accelerated simulation. The accuracy of the obtained estimates is illustrated by numerical examples.
