Title:
Uncertainty Quantification for Reliability Analysis and Decision Making in Engineering Systems
Abstract:
This talk will discuss current research on uncertainty quantification for reliability assessment and decision-making in engineering systems. Model-based simulation is attractive for the reliability analysis of systems that are too large and complex for full-scale testing. However, model-based simulation involves many approximations and assumptions, and thus confidence in the simulation result is an important consideration in risk-informed decision-making. Sources of uncertainty are both aleatory and epistemic, stemming from natural variability, information uncertainty, and modeling approximations. The presentation will draw on ongoing research projects in civil, mechanical and aerospace engineering to discuss (1) the effects of data uncertainty and model uncertainty (both due to model form assumptions and solution approximations) on reliability assessment of multi-physics, multi-scale systems; (2) Bayesian networks for integrating heterogeneous information from multiple sources (models, tests, experts) in multiple formats; and (3) decision support for risk management throughout the life cycle of engineered systems.
