摘　　要：用模糊数学方法 ,对模糊目标时的稳健设计原理进行了研究 ,提出了望目特性和望小特性稳健设计的模糊概率型的稳健性准则 .针对在一般的模糊优化设计中模糊约束条件的不稳健性 ,提出了模糊约束条件的稳健性准则 ,既要在干扰因素下提交设计质量的抗干扰能力和优质率 ,又要保证设计点的可行稳健性 .在此基础上 ,建立了模糊目标与模糊约束条件下的模糊稳健设计数学模型 ,给出了模糊稳健设计的实例 .这是一种新的稳健设计原理 ,具有工程应用前景 .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 robustness problem of fuzzy restriction conditions was analyzed, and it was pointed out that the fuzzy restriction condition in general fuzzy optimal design didn′t have 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.
