英文摘要：

A collaborative parameter robust optimization based on generalized dynamic constraints network （GDCN） was presented. The uncertainty of parameter in the concurrent and collaborative design was analyzed, and the GDCN was presented to manage the uncertainty. The frame of collaborative parameter robust design based on GDCN was developed. The model of multi objective robust optimization（MORO） with preference information was presented, at the same time the robustness of target attributes and dynamic constraints feasible domain were considered. And the flow of robust optimization based on MORO was given. Finally, a design example of engine was analyzed to show effectiveness of this proposed method.
