It can be said the design is robust and is acceptive . from the view , the key of robust design can be refered as a optimization problem , which demanding the design is robust substatuded to restrictions . after set forth the general concept of robust , the thesis give a example , comparing and analysising the general optimization methods and robust design through a example 从这一点看，稳健优化设计的核心是优化设计问题，要求在满足约束条件下达到产品质量稳健性的目的，本文在阐述了稳健优化设计的一般概念后，重点阐述了基于容差模型的稳健优化设计方法，论述各参数的容差对设计函数的影响及是如何传递给目标函数的，从而使设计解是稳健可行的。
