WebSafety engineers traditionally perform analysis, such as fault tree analysis [24], based on information synthesized from several sources, including informal design models and requirements documents. Unfortunately, these analyses are highly subjective and dependent on the skill of the engineer. 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. cincinnati ohio fidelity investments
