Abstract:
This paper summarizes the discussion at the Approximation Methods Panel that was held at the 9th AIAA/ISSMO Symposium on Multidisciplinary Analysis & Optimization in Atlanta, GA on September 2-4, 2002. The objective in the panel was to discuss the current state-of-the-art of approximation methods and identify future research directions important to the community. The panel consisted of five representatives from industry and government: Andrew J. Booker from The Boeing Company, Dipankar Ghosh from Vanderplaats Research & Development, Anthony A. Giunta from Sandia National Laboratories, Patrick N. Koch from Engineous Software, and Ren-Jye Yang from Ford Motor Company. Each panelist was asked to (1) describe the current state-of-the-art of the approximation methods used by his company, (2) give one or two brief examples of typical uses of these methods by his company, (3) describe the current challenges in the use and adoption of approximation methods within your company, and (4) identify future research directions in approximation methods. Common themes that arose from the discussion included differentiating between Design of Experiments and Design and Analysis of Computer Experiments, visualizing experimental results and data from approximation models, capturing uncertainty with approximation methods, handling problems with large numbers of variables, and educating engineers in using approximation methods.
