Customized Requirements Driven Multivariate Quality Control for Steelmaking Process
Advanced Engineering Forum
In this paper, a new SPC based quality control process model for steelmaking industry is established, in which a Customer Requirements Weighted-Principal Component Analysis (CRW-PCA) method is proposed, the multivariate control charts based on this method can make special emphasis on the controlling of steelmaking quality characters response to customer's special requirements. Practices show that compared with the traditional PCA-based multivariate control chart, the multivariate control chartsdoi:10.4028/www.scientific.net/aef.6-7.474 fatcat:2y4c6gfe5bbndecmgfdp6mu5lq
