Markovian queueing systems represent a cornerstone in the study of stochastic processes, offering a robust framework for modelling the random nature of service and arrival processes across diverse ...

The Annals of Applied Probability, Vol. 5, No. 3 (Aug., 1995), pp. 637-665 (29 pages) This paper studies the fluid approximation (also known as the functional strong law of large numbers) and the ...

Retrial queueing systems represent a class of models in which arriving customers, upon encountering a busy or unavailable server, enter a virtual waiting room—commonly referred to as an orbit—to ...

In this paper we study the asymptotic behavior of a general class of product-form closed queueing networks as the population size grows large. We first characterize the asymptotic behavior of the ...

You've probably already noticed the difference between the way people line up at McDonald's and the way they line up at Starbucks. At McDonald's, a single employee handles your entire order. Even if ...

Professor George Zhang teaches data analysis, stochastic modelling, and decision making courses in the Department of Decision Sciences, College of Business and Economics at Western Washington ...

Are checkout lines slowing you down this holiday season? With some simple queueing theory stores could could make lines more efficient, saving themselves money, and helping you get out of the stores ...
