REAL-TIME SAFETY RISK ASSESSMENT METHOD BASED ON THE COMBINATION OF EVENT TREE AND FAULT TREE

摘要

The system safety risk is the significant basis for being acquainted with the safety status of system and avoiding serious accident. For the sake of assessing the real-time safety risk, this paper proposes a real-time risk assessment method which is on the basis of analyzing the risk factors of system and presenting typical model of risk factors, and which executes the real-time safety risk assessment of system based on the combination of event tree and fault tree. Simultaneously we discuss the difficulty in the real-time assessment. In order to express the method explicitly, a case is used to explain the mind of real-time risk assessment.
