INTEGRATED EXPERT SYSTEM FOR IDENTIFYING ABNORMAL EVENTS IN AN INDUSTRIAL PLANT

摘要

A computer-implemented integrated expert system for the identification of abnormal events in an industrial plant. The expert system integrates a model- based expert system with a rule-based expert system. The model-based expert system receives data on the operating conditions of a process unit in the industrial plant and calculates one or more results that determine whether the process unit is operating abnormally. The rule-based expert system also receives data on the operating conditions of the process unit and applies its rules to the process data. The rule-based expert system also applies its rules to the one or more results generated by the model-based expert system. The integrated system may also suppress any redundant messages generated by the model-based expert system.
