Detailed fault type data provides a basis for fault management and helps to formulate fault handling priorities and strategies. Constructing a fault causal network can analyze the correlation between different faults and reveal the propagation path and impact range of the fault. Through the fault propagation model, the potential impact of the fault can be predicted, countermeasures can be taken in advance, and the fault risk can be reduced. The fault causal network and propagation model provide decision makers with a panoramic view of fault propagation, which helps to formulate a more scientific fault management strategy.
