Title: Overview of Optimization Under Uncertainty R&D within the DAKOTA Project Speaker: Mike Eldred, Sandia National Laboratories Location: CSRI Building, Room 90 (Sandia NM) Abstract: Uncertainties must be properly modeled in order to quantify risk and enable the design of systems that are both robust and reliable. A number of capabilities for optimization under uncertainty (OUU) have been developed at Sandia and deployed to users through the DAKOTA software toolkit. This talk will overview these capabilities, as well as describe the uncertainty quantification and optimization foundations on which they are based. Of particular interest are sampling, reliability, polynomial chaos, and epistemic uncertainty quantification (UQ) methods, which lead to OUU approaches that are tailored to the strengths of each of these UQ techniques. Applications of OUU will be presented for robust design of inertial confinement fusion capsules and reliability-based design of micro-electro-mechanical systems.
