Human Aspact Quantitative vs.Qualitative It is wrong to think of MDO as"automated"or "push- button"design: Huean mveenveness,creanvit,intirton.experience Conceiving The human strengths(creativity,intuition,decision- different concepts making)and computer strengths(memory,speed, objectivity)should complement each other The human will always be the Meta-designer Evalation. selection of Challenges of defining an effective interface- c0p市店 continuous vs.discrete thinking Challenges of visualization in multidimensional space, e.g.search path from initial design to final design Human mind is the driving force in the design process.MDO is a Human element is a key component in way of formalizing the quantitative tool to apply the best trade-offs. any successful system design methodology System Engineering by J.J.Gao ③cLao System Engineering by J.J.Gao ③cLco 国 10 Architecture V.S.Design Architecture V.S.Design Architecture selects the concept,decomposition and mapping of form to function Architecture establishes the vector of design and operating parameters Design selects the values of the vector of variables This is what optimization is good for Some work in"architecture"is just an exhaustive search over the design of one architecture Design Variables X System Engineering by J.J.Gao ③cts0 11 System Engineering by .J.Gao ③ctse 12+ - System Engineering by J.
