Weak Convergence of a Sequence of Queueing and Storage Processes to a Singular Diffusion.
Abstract
It has been known for a long time that heavy traffic limit theorems in queueing theory are but a special case of the so-called diffusion approximation in Physics and Genetics. Take for example Kingman's (1962) heavy traffic approximation for the stationary waiting time distribution for a sequence of GI/GI/1 queues Q(sigma) depending on a parameter sigma. Denote the waiting time, excluding service, or the nth customer by W(n,sigma) and let U(n,sigma) = S(n,sigma) - T(n,sigma) where S(n,sigma) = service time of the nth cutstomer and T(n,sigma) = inter arrival time between the nth and (n + 1)st customer and assume E(U(n,sigma)) = variance of U(n,sigma) = sigma squared, sigma > 0.
