Abstract
Single-server queueing systems with mixed traffic are
a flexible modeling tool that have been used to analyze
polling systems and database striping strategies. They
also have applications in manufacturing and telecommunication
systems. Ordinary (open) customers arrive according to
a Poisson process, receive service, and leave the system.
Permanent (closed) customers remain in the system, reentering
the queue after receiving service. This work examines the
transient behavior of the permanent customers. The cycle
times and output/departure process for the permanent customers
are described.
