Modelling Dependent Component Failures with Domino Effects
The objective of this contribution is to widen the art of modelling dependencies between components in a reliability analysis. The presented convolution-based approach allows quantifying the impact of a component failure on another system component — the so-called domino effect — and calculating failure probabilities of non-repairable systems. The contribution discusses the mathematical fundamentals and the applicability of the approach. Domino coupling probabilities are used to quantify the impact of one component on the other.
