Quasi-Birth-and-Death Processes and Queueing Models
Abstract
Quasi-birth-and-death processes (QBDs) are generalizations of simple
random walks to a state space with a semi-infinite lattice structure.
They arise naturally in various queueing models and have a rich
mathematical theory, which will be reviewed. The speaker will
describe recent results and several open problems and suggest QBDs
whose numerical exploration will provide important new insights into
various questions of applied interest.
