Two Cascade Fault Models in Bayesian Networks

Based on a common Bayesian network that models a system which has a cascade fault, this paper designs a new Bayesian network model and compares the two models according to experiment data. The experimental result shows that the new one is more consistent with the practical situation. The paper also gives a method for constructing a Bayesian network that models a system which has a cascade fault, a method efficient in the field of detecting cascade fault.
