Abstract

Queuing systems with finite buffers are reasonable models for many manufacturing, telecommunication, and healthcare systems. Although some approximations exist, the exact analysis of multi-server and finite-buffer queues with general service time distribution is unknown. However, the phase-type assumption for service time is a frequently used approach. Because the Cox distribution, a kind of phase-type distribution, provides a good representation of data with great variability, it has a vast area of application in modeling service times.
