Sistemi ad eventi discreti. II edizione

Abstract

Discrete-event systems are characterized by a discrete state space that is not necessarily numerical. The dynamic behavior of such systems is driven by the occurrence of events that are also discrete and that, occurring with irregular cadence not necessarily known a priori, result in instantaneous changes of state. The activities identified by the events are typically concurrent and require synchronization and control strategies. Significant examples can be found in manufacturing processes, computer networks, transportation, and communications. Discrete Event Systems is designed as a textbook suitable for undergraduate and graduate courses. It introduces and guides the reader, presenting an overview of the different models used in this field (automata, Markov chains, queues, Petri nets, max-plus algebra) and the different simulation, analysis and control methodologies developed for such models. The various chapters, being sufficiently independent of each other, can also be individually used in a broad educational spectrum, for example as teaching support for a project or dissertation, or as introductory reading for doctoral students. Although the topics covered are approached from a purely systems perspective, the book is of interest not only to students of courses in the area of Information Engineering (automation, telecommunications, electronics, computer science) but also to students in the areas of Civil Engineering and Industrial Engineering (chemical, transportation, management, mechanical), as well as Mathematics (computer science, operations research), in which the study of discrete-event systems assumes particular relevance.
