Abstract
Several variants of multiple server queues with Poisson input, exponentially distributed service demands and processor sharing discipline are considered, in which the arrival rate and the service capacity may depend on the actual number of customers in the system. These queues are approximated by a sequence of models featuring a new natural discipline called Random Quantum Allocation (RQA) operating in discrete time. This approach can be used for the numerical approximation of waiting and response time distributions for processor sharing queues. Numerical examples are provided for open and closed M/M/N processor sharing queues. In particular the effect of the number of parallel processors on the response time distribution under the condition of fixed total service capacity is discussed.
The main part of this research was carried out at the Technische Universität Braunschweig. The author is now with Siemens AG, Bereich Verkehrstechnik, Ackerstraße 22, D-38126 Braunschweig
