This book uniquely combines queuing networks with Bayesian, Boolean, and random networks and provides an interdisciplinary approach by including applications in biology, communications, mathematics, engineering, and operations management. Combining techniques from stochastic processes and graph theory to analyze the behavior of networks, the book includes science and engineering applications, many practical examples that include related mathematical details, and numerous solved examples. It serves as both a reference for researchers and network professionals and as an upper-undergraduate and graduate-level coursebook.
