Decentralized supervisory control with single-bit communications

We present a preliminary examination of constrained communication between controllers of a decentralized discrete-event system. Previously, controllers have communicated state estimates and/or partially observed sequences of events. The communication protocol presented here restricts controllers to the communication of a single symbol. The effect of this "singlebit" communication on the generation of a useful communication policy to solve the control problem is examined. The issue of the decidability of decentralized discrete-event control problems with communication is also briefly discussed
