Supervisory control of discrete-event systems

Our proposed research lies in the branch of engineering and applied mathematics called "automatic control" or sometimes "cybernetics", namely the science and technology of feedback systems. Such systems are designed to maintain some critical variable or variables within an acceptable range. For instance, an aircraft's automatic pilot corrects for wind disturbances which might otherwise drive the plane off course, perhaps disastrously. Of specific interest to us are systems, like traffic systems, which must respond to sudden "events", like the arrival in a service queue of a vehicle; and manufacturing systems, which must respond to a new part order or machine breakdown. Another example is the pushbutton system in a modern automobile which, although "randomly" activated by the motorist, should be designed never to commit a logical error like "hangup" or blocking.
