Abstract

The influence of safety risk assessment is being gradually recog-nized along with increasing importance of system safety. In view of the effectiveness of probabilistic influence diagram (PID) in probability reasoning, PID was introduced into system safety risk assessment. Combining the object-oriented method of PID with the traditional risk analysis method, a model of system safety risk probability was successfully constructed. To support the construc-tion and reduction analysis of PID properly, an editor was designed. The syntax and semantics of the editor were detailed in the paper, and its technical feasibility in risk analysis was demonstrated in a case study. Based on graph transformation and reduction algo-rithms of PID, the visualization and describing ability of reduction analysis of PID has been further strengthened, and its semi-automation is achieved by the editor.
