Title: Queueing Networks and Stability
Speaker: Maury Bramson

Abstract: Queueing networks refer to a large collection of probabilistic models, where one wishes to understand how lines (or queues) of people or jobs behave. Such networks will be applicable, for instance, to lines of people at a bank or supermarket, jobs to be prioritized in a computer network, or the prioritizing of jobs in an industrial process, such as the manufacture of semiconductor wafers (which is itself a complicated procedure). A basic question one needs to ask for such systems concerns when they are stable, that is, when the service of people (or jobs) is fast enough compared with the rate at which they arrive, so that the lines do not get larger and larger over time. Interestingly, there are important paradoxes, where the lines will grow even though the service assigned to the people/jobs is performed at a faster rate than the rate at which the people/jobs enter the network. The purpose of this lecture is to examine these paradoxes.

Other Opportunities:




The Math Club meets most Thursdays of the semester at 12:20 pm in Vincent 570.

The Math Club is open to all undergraduate students in mathematics; students from other programs are also welcome. The goal of the club is to provide a forum for students to meet and discuss issues of common interest, such as careers in mathematics, research, graduate school, academic concerns, internship opportunities, scholarships, special lectures and summer programs.


The Math Club is very grateful to Professor Willard and Mrs. Jane Miller for their generous donations to promote student activities.
