Abstract:

A Bayesian modeling and parameter optimization method considering noise factor is proposed to deal with the robust parameter design problem of non-normal response. Firstly, considering the empirical Bayesian prior information, the Bayesian generalized linear model is used to construct the functional relationship between the design factors and the output response. Secondly, assuming that the noise factor follows the known distribution, the Bayesian sampling technique is used to obtain the analog sampling value of output response considering the variation of noise factor. Then, based on the given product specification, the posterior probability function is constructed by using the sampling value of the output response, and the constructed conformance posterior probability function is optimized by a genetic algorithm to obtain the parameter design values that are robust to the fluctuation of noise factors. Finally, the effectiveness of the proposed method is verified by an actual case. The research results show that the proposed method effectively describes the impact of noise factors fluctuation on product or process quality, and obtains more robust and reliable parameter design values.
