Fault tree analysis for system modeling in case of intentional EMI

[摘要] The complexity of modern systems on the one hand and the rising threat ofintentional electromagnetic interference (IEMI) on the other hand increasethe necessity for systematical risk analysis. Most of the problems can not betreated deterministically since slight changes in the configuration (source,position, polarization, ...) can dramatically change the outcome of anevent. For that purpose, methods known from probabilistic risk analysis canbe applied. One of the most common approaches is the fault tree analysis(FTA). The FTA is used to determine the system failure probability and alsothe main contributors to its failure. In this paper the fault tree analysisis introduced and a possible application of that method is shown using asmall computer network as an example. The constraints of this methods areexplained and conclusions for further research are drawn.
