Features

  • Introduces AMSs with focus on their deadlock control issues
  • Discusses the basic concepts and definitions of Petri nets, including siphons, P-invariants, state equations, reachable sets, and reachability graphs
  • Formulates symbolic computation and analysis methods of bounded Petri nets, by using BDDs which are capable of representing large sets of markings with small data structures
  • Presents a deadlock prevention strategy by using the theory of regions
  • Considers the design of a maximally permissive liveness-enforcing supervisor for manufacturing-oriented Petri net models existing in the literature
  • Examines the design of a maximally permissive liveness enforcing supervisor with a compact supervisory structure by minimizing the number of monitors
  • Supplies a well trade-off among the three criteria: behavioral permissiveness, structural complexity, and computational complexity

Summary

This monograph presents the state-of-the-art developments in the design of behaviorally and structurally optimal livenessen-forcing Petri net supervisors with computationally tractable approaches. It details optimal supervisory control problems arising in automated production systems and outlines a methodology to achieve the optimality purposes of deadlock prevention via converting a variety of problems under consideration into integer linear programming models. The book includes a reference bibliography at the end of each chapter and a complete index.
