ABSTRACT
Like the descriptive models in “classical” queueing theory, optimal design models may be classified according to such parameters as the arrival rate(s), the service rate(s), the interarrival-time and service-time distributions, and the queue discipline(s). In addition, the queueing system under study may be a network with several facilities and/or classes of customers, in which case the nature of the flows of the classes among the various facilities must also be specified.
