A10 Needs- from students A 2001 survey of undergraduate students (AerolAstro)-in conjunction with new Dept head h searc There is a perceived lack of understanding and training in modern design methods using state-of-the-art CADICAE/CAM technology and design optimization Individual students have suggested the addition of a short and intense course of rapid prototyping, combined with design optimization 16.810(16.682) Massachusetts Institute of Technology

Needs – from students A 2001 survey of undergraduate students (Aero/Astro) – in conjunction with new Dept. head search - There is a perceived lack of understanding and training in modern design methods using state-of-the-art CAD/CAE/CAM technology and design optimization. - Individual students have suggested the addition of a short and intense course of rapid prototyping, combined with design optimization. 16.810 (16.682) 7

IGA10 Needs-from industry Industry wants/needs(dwo interpretation) Engineers who are trained in integrated design methods and tools have personally carried out the design process from conception to implementation at least once Engineers who have an initial understanding of importance of requirements complementary roles of humans and computers in design difficulties at the cad/cae caM domain interfaces value of optimization importance of trading off competing objectives difference between predicted vs actual behavior of the artifacts they design 16.810(16.682) Massachusetts Institute of Technology

Needs – from industry Industry wants/needs (dWo interpretation) Engineers who - are trained in integrated design methods and tools - have personally carried out the design process from conception to implementation at least once. Engineers who have an initial understanding of: - importance of requirements - complementary roles of humans and computers in design - difficulties at the CAD/CAE/CAM domain interfaces - value of optimization - importance of trading off competing objectives - difference between predicted vs actual behavior of the artifacts they design 16.810 (16.682) 8

IGB10 An engineer should be able to Determine quickly how things work Determine what customers want Create a concept Use abstractions/math models to improve a concept Build or create a prototype version Quantitatively and robustly test a prototype to improve concept and to predict Determine whether customer value and enterprise value are aligned (business sense) Communicate all of the above to various audiences e Much of this requires domain-specific knowledge"and experience Several require systems thinking and statistical thinking All require teamwork, leadership, and societal awareness Courtesy of Prof. Chris Magee.
