Title: Waiting Time Distribution of Tandem Queues with Correlated Service Nodes
Author(s): Alfred Akinsete*+
Companies: Marshall University
Address: Department of Mathematics, Huntingnton, WV, 25755, United States
Keywords: Queueing network ; probability ; service time ; interarrival-interval
Abstract:

This work discusses the waiting time distribution of correlated queues in tandem, where the service time of a customer arriving for service is correlated with its preceding interarrival interval. The correlation arises as a result of finite buffer spaces between the service nodes of queues in tandem, causing a blockage of customers' services. Hence, the probability distribution of the state of such a system cannot be expressed in product form. Using the Laplace Stieltjes Transform (LST), we obtain the waiting time and sojourn time distributions of two queues in tandem.
