Abstract

An intelligent diagnostic methodology is proposed in this paper that combines piping and instrumentation information with hazard analysis results. The process model is represented as a hierarchically ordered set of blended HAZOP and FMEA structures. A diagnostic reasoning method is developed over that structure that combines backward and forward reasoning to gradually improve the fault isolation based on the temporal evaluation of the observed symptoms. The method is illustrated on a simple industrially relevant case study.
