Research Area

My research interests are in the general area of stochastic models in Operations Research. I have done work in queueing theory, reliability theory, and stochastic scheduling, although queueing theory has been my primary interest.

My recent research focuses on polling models in queueing theory. Polling models are used to represent systems of multiple service facilities that are attended by a single server that travels from queue to queue in some prescribed manner. These models have many important applications (materials handling, machine maintenance and repair, computer networks, traffic control, telephone switching systems, etc.) and, in general, they are very complicated. Because of the complexity involved, it would be advantageous to be able to decompose the analysis of these models into simpler modules, and then to study and link together the simpler pieces. The objective of my current research effort is to develop general, simplifying, decompositions for polling models. This work, in collaboration with Professor Robert B. Cooper (Florida Atlantic University) and Professor Mandyam M. Srinivasan (University of Tennessee at Knoxville), was funded by a three-year grant from the National Science Foundation.
