Abstract
Operators across various industrial domains (e.g., aerospace, transportation, and nuclear energy), their customers and the general public share the utmost interest in safety. Maintaining and improving the safety of complex utilities requires mathematical modelling of a system under study and its potential failures. In an established approach, one uses formalisms combining probabilistic data for individual components and the structural information. The amount and type of dependencies between parts of the system that can be expressed in the model determine the complexity of the analysis. I will talk about the algorithmic challenges posed by the analysis of different formalisms. We start with the standard event tree/fault tree model and discuss its extensions by adding state information. Most examples and practical motivation of studied features come from the area of Nuclear Safety. I will present the current development and future directions in the safety assessment tool suite RiskSpectrum.
