The use of an expert system along with fuzzy fault tree analysis is discussed in connection with fault diagnosis of a hazardous waste incineration facility. This fault tree is a diagrammatic representation of knowledge about the modes of failure of the incineration facility, and is readily transformed into a collection of production or IF-THEN rules. By incorporating the notion of fuzzy probabilities into fault tree analysis, the expert system is capable of drawing meaningful conclusions from uncertain situations. This greatly enhances the flexibility of the program. The present work utilizes M. 1, a commercially available expert system shell, in building the expert system. The fault tree for the hazardous waste incineration system, provided by a domain expert, is represented in the form of IF-THEN rules in the shell. Examples of fault detection are presented.
