Safety Assessment Model Based on Dynamic Bayesian Network
To take full advantage of the historical information,we adopt dynamic Bayesian networks and discrete-time Bayesian networks to describe the event trees or dynamic fault trees.On this basis of the regulation,corresponding dynamic Bayesian networks and discretetime Bayesian networks models are established for safety assessment in timing system.When the discrete-time time Bayesian network of dynamic fault trees is acquired,the Bayesian network is used to study the consequences probability,key degree and computation method.A simulated banking transaction system is analyzed and assessed by above models.The results show that the safety assessment scheme can provide model without subjectivity,which raises the credibility of model.In addition,it can obtain general assessment results and acquire more extensive diagnostics and information.
