Research on Method for Evaluating Reliability of Systems Based on BN
Zeng Qiong · Jisuanji fangzhen · 2009
In order to evaluate complex behaviors and interactions between their components of dynamic systems,a new method for modeling and analysing dynamic systems reliability based on BN was presented.By using the advantages of uncertainty reasoning and figurative expression of Bayesian network,system components' behaviors and interactions were captured well-defined.Combining,in a structured way,the various 'basic' Bayesian network constructs enables the user to construct,in a modular and hierarchical fashion,the system model.Experiment results show that the method is feasible and valid.Sensitivity is improved,and uncertainty is lessened.
