0800 - 0845 KEYNOTE ADDRESS: Optimization Technology in Commercial Industry Ballroom A-B Achille Messac, Professor, Rensselaer Polytechnic Institute Conference General Chair: Conference overview and speakers introduction ---- Shirley Ann Jackson, President, Rensselaer Polytechnic Institute: Welcoming Remarks ---- James R. Scapa, President and CEO, Altair Engineering, Inc. ---- Keynote Abstract: Competitive pressures continue to force product improvement demands on engineering and design departments. Being able to structurally optimize a component for a desired performance outcome in the pre-design phase can mean more time for product innovation and shorter time to market. Moreover, there is a significant movement to not only design for product performance but also for robustness and reliability. Optimization technology and methods are playing an increasingly more important role in commercial industry. This keynote address will discuss optimization trends in product design that are being embraced by the manufacturing community.

This panel follows up on a similar panel entitled "48-MAO-48 Special Panel Session: Multidisciplinary Design Optimization: Accomplishments and New Frontiers" held at MAO 2002 (Atlanta). This year’s panel will focus on metrics for assessing the true impact and benefits of MDO. This will be done by means of case studies that highlight the differences in performance, cost and robustness of traditional, sequentially designed versus concurrently designed systems and products. Other important topics are the issue of coupling in systems, as well as challenges of model fidelity, visualization and institutional change to enable effective use and dissemination of MDO techniques in various project organizations. The panel will attempt to point out promising future research directions for MDO/MA&O. Panel: J. Sobieszczanski-Sobieski - - NASA Langley , A. Striz - - University of Oklahoma, A.

Session 21-MAO-21 1400 - 1630 PANEL: Ubiquitous and Massively Parallel Computing Pearl Street Room Panel explores the basic concepts and implications of parallel processing, grid computing, and other massively parallel computing schemes. The availability of ubiquitous computing will increase computational power, memory and speed by several orders of magnitude in coming decades. This will potentially pose new challenges, but also enable new opportunities in MDO, because the tradeoff between model fidelity and breadth of searching design spaces has been an important limiting factor in the past. This panel will explore the basic concepts and implications of parallel processing, grid computing and other massively parallel computing schemes. The suitability of different types of multidisciplinary problems and algorithms for parallel processing will be discussed. Panel: J. Alonso - - Stanford University, S. Benson - - Argonne National Laboratory, A. Giunta - - Sandia National Laboratories, M. Grauer - - University of Siegen, Germany Moderator/s: S. Rajan , A. Belegundu
