This text offers an account on the subject that spans both conventional and modern materials about discrete-event systems, material that, up to now, has been presented in the literature in different fields, such as the graph theory, the probability theory, the automata's theory, and the queueing theory. The book gives an introduction to the discrete-event system theory and simultaneously applies the theory to practical problems. It gives students of computer sciences, system sciences, and of electrical engineering, an account of discrete-event systems. Illustrations are included for better...
