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. WebThe explosive logic network( ELN) with two-input-oneoutput was designed with three explosive logic gap null gates. The time window of the output of the ELN was given,after which the dynamic fault tree analysis was implemented. Two dynamic failure modes of the ELN were obtained,and then their own Markov transition processes were established.
WebFault tree analysis (FTA) is extensively used for reliability and safety assessment of complex and critical engineering systems. One of the important limitations of conventional FTA is the inability for one to incorporate complex component interactions such as sequence dependent failures. Dynamic gates are introduced to extend conventional FT ... WebDynamic fault trees (DFT) extend standard fault trees by allowing the modeling of complex system components' behaviors and interactions. Being a high level model and easy to use, DFT are experiencing a growing success among reliability engineers. Unfortunately, a number of issues still remains when using DFT. Briefly, these issues are (1) a lack of …
