A real time expert system for continuous assistance in process control: A successful approach

Abstract

Ruled based systems have proven to be suitable for monitoring and diagnosis in process industry. However, up to now, they do not take into account the effect of their recommendations on the process under study, which is essential for achieving a total automatization of an idustrial plant. Besides, cooperation with other AI techniques within a consistent framework seems essential for tackling all aspects of industry problem. The system described in this paper tries to adress these two issues. The system has been installed in a petrochemical plant in Cartagena, Spain, showing very promising results.
