Abstract:
|
Many industrial process optimization methods rely on empirical models that relate output responses to a set of design variables. One of the most crucial problems in process optimization is how to efficiently implement model selection and model estimation . This paper presents a Bayesian hierarchical modeling approach to process optimization based on the seemingly unrelated regression (SUR) models . This approach can estimate a set of predictors to be included in a model based on a Bayesian hierarchical procedure (i.e., model selection) and then give model prediction based on a Bayesian SUR model (i.e., model Meanwhile, a two stage optimization strategy considering practitioners preference information is proposed in process optimization , which initially finds a set of non dominated input setting s and then determines the best one based on the similarity to an ideal solution method. The performance and effectiveness of the proposed approach is illustrated with both simulation studies and a case study. The comparison results demonstrate that the proposed approach can be a good alternative to existing process optimization methods.
