The recent explosion of technological advances in computer and communications systems has caused a resurgence of interest in queuing theory and its applications. The progress of research has uncovered several new developments, and among those studied in depth here are algorithmic and numerical approaches, design and control, inference, simulation techniques, and queuing networks. The book provides a broad analysis of current research activity and includes chapters by internationally established authors. Professor N. U. Prabhu also contributes his thoughts and perspectives on recent trends and future developments in queuing theory. This volume will be of value and interest to operations researchers, statisticians, and all those concerned with queuing theory as an important field within the discipline of applied probability.
