Research on Risk Assessment Model of Open Press Blunt Hand Accident

Abstract:

Basic principle and inference algorithm of Bayesian network (BN) were emphasized. As to the Fault Tree with basic events of common cause failure, accident probability cannot be computed correctly. An open press blunt hand accident risk assessment BN model was set up, in addition, the BN nodes of common cause failure were illustrated and the accident probability of occurrence was obtained. The discussions about computed results indicate that regarding to system with unit events of common cause failure or interdependent events, result of accident probability computed from a BN model is higher than that computed from the Fault Tree/Event Tree model.
