Abstract: By means of fuzzy mathematical method,the principle of robust design with fuzzy objective was studied and the rules of robust design based on fuzzy probability were put forward when the design objective had definite purposed character and had small the best character. The robu stness problem of fuzzy restriction conditions was analyzed, and it was pointed out that the fuzzy restriction condition in general fuzzy optimal design didn' thave feasible robustness. As a result, the principle and the modeling method of fuzzy robust design with fuzzy objective and fuzzy restriction conditions were presented. A fuzzy robust design example was presented finally.
