In this paper, real-time process data are aligned in time-order with periodic destructive test data of wood composite panel strength for the purpose of predictive modeling. Real time predictive models of strength properties during product manufacture may reduce rework, scrap, and avoid higher costs of unnecessary operating targets between the time periods of destructive strength samples. A modified principal component analysis (PCA) is used to develop an empirical model to predict the internal bond (IB) of particleboard (PB) based on a selected subset of process variables. These process variables are pre-selected by using variables correlated with IB. Our modified PCA is used on these selected standardized process variables to obtain transformed composite variables or modes. The ten modes are reduced to three using correlation criteria and the three best modes are used to generate an empirical model to predict IB. Model results for the most often produced PB at the mill test site are presented in the paper. The IB model generated from the selected variables has a root mean square error of prediction (RMSEP) for IB of 79.979 kPa, which represents 20% RMSEP improvements for this manufacturing setting.
