Modular supervisory control of networked discrete-event systems

In this paper, modular and more generally coordination supervisory control of networked concurrent discrete-event systems (DES) is studied. We are interested in comparison of monolithic control synthesis with modular control synthesis if communication delays in both control and observation channels are taken into account. It is shown that unlike standard DES framework, modular, and more generally, coordination control can be more permissive than monolithic control in some cases because of smaller communication delays in the local systems.
