Fuzzy Design Method of Product Quality Robustness

摘要

In order to express information on the quality grade of product designed, the target value of product quality design was described with a fuzzy number in this paper. The rule of robust design with a fuzzy target was analyzed with fuzzy probability theory , then the principle and modeling method of fuzzy robust design for a high quality product were put forward. With this new method used, the high-quality ratio of the product designed could be increased , and the ability to resist the influence of various disturbing factors and noise factors could be enhanced.
