The BDD-based assessment method of project safety risk

Abstract

To assess project safety risk, this paper proposes a quantitative method based on BDD(Binary Decision Diagram). After constructing the BDD with fault tree of safety risk event, the method traverses the BDD and computes the occurrence probability of risk event. For the convenient implementation with computer program, it can get analysis results efficiently and accurately. So it is very suitable for the risk assessment of large projects.
