This article addresses questions of sensitivity of output values in engineering models with respect to variations in the input parameters. Such an analysis is an important ingredient in the assessment of the safety and reliability of structures. A major challenge in engineering applications lies in the fact that high computational costs have to be faced. Methods have to be developed that admit assertions about the sensitivity of the output with as few computations as possible. This article serves to explore various techniques from imprecise probability that may contribute to achieving this goal.
Keywords. Reliability of structures, sensitivity analysis, random sets, fuzzy sets, simulation methods, aerospace engineering
