Decision uncertainties in natural hazard risk management: damage potential

摘要

The infrastructure of energy production facilities is vulnerable to natural hazards, especially in Alpine environments. The determination of risk requires the knowledge of the probability of a natural hazard event and the associated intensity and the damage potential (vulnerability), which is site and object specific. Up to now a qualitative risk assessment was standard praxis in energy production facilities, but in the past years a quantitative risk analysis gained in importance, including the determination of uncertainties. In this paper we introduce a method on how to consider ranges of object values (€) and ranges in the damage susceptibility of different types of objects in risk calculation.
