We describe an affordable method for designing in the conceptual stage
using relatively high-fidelity concurrent systems analysis. Our metho
d is rooted in three domains, namely, the design of experiments, the r
esponse surface methodology, and the compromise decision support probl
em. A sequential experimentation strategy as well as the heuristic rul
es for creating high-order response surface models are introduced as a
cost-effective approach to applying the statistical experimentation m
ethods in design of complex systems. A high-speed civil transport airc
raft design is used as an example to illustrate the potential of our a
pproach.
