In this paper, we revise and further investigate the coordination control approach proposed for supervisory control of distributed discrete-event systems with synchronous communication based on the Ramadge-Wonham  ...  In other words, unless P=NP, it is not possible to find a polynomial algorithm to compute the minimal coordinator with respect to the number of events.  ...  Research of two first authors was supported by RVO: 67985840.  ...

We employ supervisory controllers to safely coordinate high-level discrete(-event) behavior of distributed components of complex systems.  ...  Supervisory controllers observe discrete-event system behavior, make a decision on allowed activities, and communicate the control signals to the involved parties.  ...  This gave rise to supervisory control theory of discrete-event systems [20, 8] that studies automatic synthesis of (discrete-event) models of supervisory control software.  ...
