Two UI engineers win Black and Decker best paper award

IOWA CITY, Iowa -- Two University of Iowa College of Engineering researchers have received the Black and Decker Best Paper Award in the American Society of Mechanical Engineers (ASME) Design Automation Conference during the 2001 ASME International Design Engineering Technical Conferences in Pittsburgh. The two are K.K. Choi, professor of mechanical engineering and director of the Center for Computer-Aided Design (CCAD), and his mechanical engineering and CCAD doctoral student, Byeng-Dong Youn.

The paper, titled "Hybrid Analysis Method for Reliability-Based Design Optimization," describes a new methodology for integrating manufacturing and multidisciplinary design processes. The methodology, called "six-sigma quality control," can be used to fabricate products in diverse manufacturing environments. Choi says that six-sigma quality control involves the use of design and manufacturing processes of such high quality that they can produce less than 3.4 defects, or mistakes, per million opportunities. He adds that these processes, if used by industry, will produce not only high-quality products, but also optimized designs.

The conference, held Sept. 11, 2001, attracted some 600 researchers.
