Abstract
ABSTRACT In production and manufacturing processes, noise factors are often considered difficult or costly to observe. The emergence of advanced sensor technology has made it easier for some major equipment to obtain large amounts of online monitoring data during the production stage of a product. In this paper, a new Bayesian approach is proposed to extend offline RPD to online multi-response RPD by making full use of this additional information. As new observations of the noise factor are obtained gradually, the settings of the controllable factors are adjusted online to further reduce the influence of noise factor variations on production quality. This approach not only addresses the correlation among multiple responses but also considers the uncertainty of model parameters and the variability of noise factors. A case study and a simulation study demonstrate that the proposed approach is superior to existing methods.
