Abstract: Under the circumstance that the quality characteristics with non-normal distribution of precision compliant product,for the low predictability of quality model and the weight assignment difficulty of mean and variance problem,a robust design method based on entropy weight-Generalized Linear Model (GLM) and desirability was established.The initial sampling data were obtained with full factorial experiment and finite element method,and the quality characteristic with non-normal distribution model was built through GLM approach.The entropy weight method was used to build the mean and variance weight function.On this basis,the robust design problem was transformed into target function maximum satisfaction problem combining with desirability function to deal with variance influence on result.A numerical example showed that the robust design variables obtained by the proposed approach could solve weight distribution problem and the effect of variance volatility could be mitigated.
