Introduction to Uncertainty Quantification and Sensitivity Analysis in Engineering

Measuring the level of uncertainty in engineering design and analysis is crucial for ensuring that a system is safe, reliable, and resilient. Modern statistical analysis and machine learning have proven to be invaluable tools in this regard. This talk will explore the significance of uncertainty quantification (UQ) and sensitivity analysis (SA) for engineering design, optimization, and analysis, and how these tools can be aided by the latest advancements in statistical analysis and machine learning. The talk will introduce two distinct approaches to uncertainty UQ and SA - probabilistic and non-probabilistic, to define aleatoric and epistemic uncertainties, respectively. Two advanced statistical learning techniques will be discussed to solve uncertainty propagation problems, namely, polynomial chaos expansion and gaussian process regression. To illustrate the practical benefits of UQ and SA, the talk will conclude with real-world examples from civil and aerospace engineering.
