Study on the Fuzzy Robustness of Product Quality and Method of Fuzzy Robust Optimal Design

In order to solve the problem of robust design with fuzzy information, the fuzzy characteristics of product quality were analyzed first, and then the concept of fuzzy design target was put forward. Based on the analysis of the influence of the controllable factors and noise factors on the robustness of fuzzy design target, the basic concept of the fuzzy robustness of product quality was given, and the rule of fuzzy robust design was proposed.According to the mathematical meaning and engineering significance of this rule discussed, the modelling method of the fuzzy robust optimal design of product quality was presented. The design example and theoretical analysis make clear that the principle of the fuzzy robust optimal design of product quality is more close to the engineering reality, so it possesses wide prospects in engineering application.
