Abstract: We study the design of distributed control for large-scale discrete-event systems. Our approach, called supervisor localization, allocates external supervisory control action to individual plant components as their internal control strategies. The approach is demonstrated in detail on a benchmark application, the Production Cell: a distributed control architecture is established wherein every component acquires a set of local controllers. Further, we provide a quantitative analysis of tradeoffs between the distributed and decentralized architectures, thereby pointing the way to criteria for architectural choice.
