Abstract: | Methods are developed for approximately characterizing the departure process from a single-server queue and calculating approximate congestion measures for several single-server queues in series. These methods are modifications of the previously described asymptotic method and stationary-interval method for approximating a stochastic point process. The approximations are evaluated by comparing approximate congestion measures for queues in series with previous simulation results. |
