"Delayed and Network Queues" features recent advances in queueing theory as well as new theories, real-world queueing model applications, and practical methods for solutions. Beginning with simple analytical fundamentals, the authors present the theory of queueing systems with and without delay along with applications of network queues. In addition, the book contains a careful selection of more realistic and advanced queueing models that address the current deficiencies as needed by both academicians and researchers in engineering, management, and the mathematical sciences. Discussions of queueing models such as single- and multi-server Markovian queues with balking, reneging, delay, feedback, splitting, and blocking as well as their role in the treatment of networks of queues with and without delay and network reliability are also provided. Examples and exercises from the mathematical sciences, biomathematics, engineering, physics, business, economics, and industry are provided within each chapter. Topical coverage includes: preliminary topics such as Laplace transform, difference equations, generating functions, and differential difference equations; basics of probability such as discrete random variables, continuous random variables, and random vector; stochastic processes including Markov chain and Markov processes, random walk, poisson processes, and stationary distributions; single- and multi-server queues with and without delay; and network queues with and without delay.
