Geometry unifies process control, production control and alarm management

Abstract

Geometric process control (GPC) combines the three key plant applications of process control, production control and alarm management. GPC improves all three applications which were previously quite separate as they lacked a unifying mathematical basis. The mathematical basis for the breakthrough is the use of n-dimensional geometry together with Inselberg's co-ordinate transformation that makes it possible to see a multivariable graph containing perhaps several hundred variables (such as flows, pressures, temperatures, and product qualities) and thousands of different observations in a single picture.
