This book is dedicated to the systematization and development of models, methods, and
algorithms for queuing systems with correlated arrivals. After first setting up the basic tools
needed for the study of queuing theory, the authors concentrate on complicated systems: multiserver
systems with phase type distribution of service time or single-server queues with
arbitrary distribution of service time or semi-Markovian service. They pay special attention to
practically important retrial queues, tandem queues, and queues with unreliable servers.
Mathematical models of networks and queuing systems are widely used for the study and
optimization of various technical, physical, economic, industrial, and administrative systems, and
this book will be valuable for researchers, graduate students, and practitioners in these
domains.
