This paper came up with a new kind of design method on the basis of the traditional robust design , the robust design based on fuzzy probability and virtual reality technology , which can cover the whole life of the products , and has many merits , such as simple designing process , high efficiency , short design period and high reliability of the design accuracy and design result . there detailed two aspects , namely , improving the traditional robust design and the modem robust design 本文论述了稳健设计方法的基本原理,研究了应用基于模糊概率及虚拟现实技术的稳健设计方法进行产品设计的一般过程,分别运用实例详细演示了在模糊概率分析法,并结合数字计算机的强大优势的基础上传统的稳健设计方法和现代稳健设计方法的具体应用,得出了可靠的、符合工程实际的设计结果。
