Presented in this paper is a novel, set-based method for design coordination between coupled systems. The research is motivated by the limitations of current point-based and set-based coordination approaches with regard to enabling collaborative and interactive design. The proposed method employs design space explorations and surrogate models to process each sub-system in parallel. A global design of experiment is then performed in the space of design variables except the coupled ones. For each design point, an optimization process is employed to guarantee system consistency. The result is a set of consistent and feasible solutions which contains the potential global optima. The proposed approach will be evaluated with a realistic wing aero-structural design problem. The result (a feasible set) is expected to be similar to the one produced by the benchmark studies using the traditional all-in-one setup. Compared with the all-in-one approach, the proposed method enables distributed and parallel computation of different disciplines. Compared with the point-based approach, the proposed method promises to be more interactive and flexible by providing multiple promising design solutions.
