| Abstract: | Considering the characteristics of the maintenance decision for aircraft power converter, a new type of software structure based on Bayesian network for fault diagnosis is proposed. In the light of the fault diagnosis based on undetermined information, the functions and/or algorithms of several important modules are discussed, such as model building, database managing, model reasoning, diagnosis decision, case collection and model training. |
