UofT Department of Computer Science Seminar Schedule for
the week of January 30th, 1984
Tuesday, January 31st, 3:00 P.M., SF1105: Dr. Steve Lavenberg,
IBM Research Laboratory, Yorktown Heights, New York: "A
perspective on iterative methods for the approximate analysis of
closed queueing networks".
ABSTRACT: It is important in computer performance modelling to
develop accurate and cost effective methods for the approximate
analysis of closed queueing networks, particularly those with
multiple chains. One important class of such methods is iterative
methods. Iterative methods have the property that a set of
nonlinear equations is developed that relates, in an approximate
way, unknown performance parameters of a network and iteration is
used to solve the equations. We attempt to provide a unified view
of existing iterative methods and we also present new results
that generalize some previous methods and may prove to have better
accuracy/cot characteristics.
