Abstract To facilitate the effective solution of multidisciplinary, multiobjective complex design problems, a departure from the traditional parametric design analysis and single objective optimization approaches is necessary in the preliminary stages of design. A necessary tradeoff becomes one of efficiency vs. accuracy as approximate models are sought to allow fast analysis and effective exploration of a preliminary design space. In this paper we apply a general robust design approach for efficient and comprehensive preliminary design to a large complex system: a high speed civil transport (HSCT) aircraft. Specifically, we investigate the HSCT wing configuration design, incorporating life cycle economic uncertainties to identify economically robust solutions. The approach is built on the foundation of statistical experimentation and modeling techniques and robust design principles, and is specialized through incorporation of the compromise Decision Support Problem for multiobjective design. For large problems however, as in the HSCT example, this robust design approach developed for efficient and comprehensive design breaks down with the problem of size — combinatorial explosion in experimentation and model building with number of variables — and both efficiency and accuracy are sacrificed. Our focus in this paper is on identifying and discussing the implications and open issues associated with the problem of size for the preliminary design of large complex systems.

This paper first provides a critical review of the literature regarding the contemporary apparel (product) design process, and then proposes a new apparel design process. Apparel is a general term for products which covers dress, skirt, etc. The new apparel design process applies a so-called systematic design approach well known to field of design. The systematic design approach classifies a design into four phases, namely, task classification, conceptual design, embodiment design, and detail design. The four phases are then tailored to apparel design. The new apparel design process is thus more rational and systematic. The paper uses a gown (a type of apparel) design as a case to illustrate the benefit of this new apparel design process, i.e., improved potentials to make apparel design more creative and efficient.
