The Stored-Program Concept of Supervisory Control

Supervisory control techniques have come a long way from their humble beginnings at the turn of the century. The advent of solid-state circuitry made possible sophisticated, high-speed scanning systems capable of performing tasks never before thought practical through remote control and supervision. These new capabilities were quick to be realized. Applications of supervisory control, especially in the last few years, increased in size and complexity. Systems with planned expansion of more than one hundred remotes, almost unheard of five years ago, are becoming almost commonplace today.
