Adaptive Sampling for Risk-Averse Design and Optimization
Boyan Lazarov | 22-ERD-009
Executive Summary
We will develop a new approach to address uncertainty during the engineering design process to enable practical, computationally feasible, and scalable algorithmic solutions to reduce overall risk and optimize performance. These methods can be used to improve the design and production of new materials and additively manufactured parts in support of national security missions.
