• Grey theory
• Multiobjective optimization design
• Robust design

Based on the grey theory, the multi-objective robust design can be converted into a single objective robust design by the grey rational grade. In the stamping robust design, multi-objectives need be met, such as not resulting in crack, not resulting in wrinkle, and enough deforming. On the basis of design of experiment, each objective value was obtained by making use of FEA. The analysis of variance for the grey relational grade was implemented, and the optimum value of multi-objectives was obtained, so that the optimum combination of the factors was confirmed. It is showed that the optimum multi-objective result is obtained making use of the grey theory in the stamping, and it can be used to solve the multi-objective robust design adequately.
