Abstract

In studying the safety risk assessment expert system in petrochemical industry, the conception of fault tree based on binary decision diagrams (BDD) is proposed for fault tree analysis. Taking the boiler fouling explosion for example, the fault tree model and BDD model are built. On the basis of the fault tree model and BDD model, the stress is put on the knowledge representation (KR) of BDD based fault tree in the safety risk assessment expert system and the fault tree knowledge based mechanism of reasoning in this paper.
