摘要：

Hierarchical structure in the supervisory control of discrete-event systems is formalized in the automaton framework of Ramadge and Wonham. The setup embodies a low-level real-world model controlled by an operator and a high-level abstract model “virtually” controlled by a manager. The two levels are connected by command and information channels. Concepts of hierarchical consistency are proposed, relating high-level behavior required by the manager to low-level behavior achievable by the operator. It is shown that consistency can be realized by appropriately refining the information sent up by the operator to the manager. © 1990 IEEE
