Risk assessment of urban infrastructure networks under natural and man-made hazards is often performed by repeated computational simulations based on random samples of hazard intensities and corresponding component status. This sampling-based approach may prevent near-real-time application of probabilistic methods to hazard mitigation of infrastructure networks and risk-informed decision suppor...

Hazard analysis plays an important role in the assurance of systems’ safety. As systems are getting bigger and more complex, hazard analysis approaches face difficulties with the amount of memory required for the analysis. Big systems are modeled with a modularized model, like UML component model. Those difficulties with memory can be conquered if the analyst utilizes the modularization of the ...

Offshore oil and gas process plants are exposed to hazardous accidents such as explosion and fire, so that the structural components should resist such accidental loads. Given the possibilities of thousands of different scenarios for the occurrence of an accidental hazard, the best way to predict a reasonable size of a specific accidental load would be the employment of a probabilistic approach...

Elicitation of requirements for safety critical aeroengine control systems is dependent on the capture of core design intent and the systematic derivation of requirements addressing hazardous deviations from that intent. Derivation of these requirements is inextricably linked to the safety assessment process. Conventional civil aerospace practice (as advocated by guidelines such as ARP4754 and ...
