"This book serves as an introduction to queueing theory and provides a thorough treatment of tools such as Markov processes, renewal theory, random walks, Levy processes, matric-analytic methods, and change of measure. It also treats in detail basic structures like GI/G/1 and GI/G/s queues, Markov-modulated models, and queueing networks, and gives an introduction to areas such as storage, inventory, and insurance risk. Exercises are included, and a survey of mathematical prerequisites is given in an appendix. Students and researchers in statistics, probability theory, operations research, and industrial engineering will find this book useful.
