Outline of Final Research Achievements

We study a new method for mathematical study on the effect of flexibility in complex queueing systems including networks. This method describes those systems, which may have generally distributed inter-arrival and service times, by a piewise deterministic Markov process, PDMP for short, and uses a martingale decomposition of the PDMP by exponential type of test functions. It differs from our original plan, which uses a reflecting random walk assuming that inter-arrival and service times are exponentially distributed. We apply this method to study the stationary queue length distributions of various systems through their tail asymptotics and their limits in heavy traffic. Those results are used to study flexibility in multiclass queueing networks with static buffer priority service and parallel queues with dedicated and join shortest queue arrivals.
