Dynamic fault tree analysis

WebJun 18, 2024 · Dynamic Fault Trees (DFT) were introduced to enhance the modelling power of its static counterpart. In DFT, the expressiveness of fault tree was improved by introducing new dynamic gates. WebFirst, the dynamic fault tree analysis (DFTA) method was used to establish a DFT characterizing the dynamic interaction for the DPCSNR. Then, the dynamic Bayesian network (DBN) method was used to transform the DFT into the initial DBN (IDBN) model characterizing the dynamic interaction and time dependence for the DPCSNR.
