CyberLogic: a new system for computer control

Abstract

The rapid advance of technology during recent years has made possible the development and use of very complex manufacturing processes. A prime example of such a process is a modern oil refinery in which there are actually many processes operating concurrently. The control of such a process requires the monitoring of pressures, temperatures, flow rates, and other such variables at many points within the refinery. Based on an analysis of the variables sampled, the process is controlled by adjusting flow rates, opening and closing valves, and recording the actions taken for further analysis and evaluation of the results of such actions.
