| Abstract: | Aiming at improving genetic algorithm in fault diagnosis of machinery, we defined the probabilistic causal network for fault diagnosis.We also derived the formula for solving fault diagnosis、fault 、sets、manifestation sets、relation intensity and experience probability. The minimum value sets of formula correspond to the fault and manifestation sets. The effectiveness of this method is proved with an example. |
