Abstract
A method () for offline/online monitoring of batch processes. The method involves () decomposing a time domain of a batch process run (BPR) into several blocks and () building multivariate statistical models (MSMs) for each of them using archived data for a batch process (ABPD). ABPD comprises stored data obtained during BPRs. The method also involves () retrieving recently stored data (RSD) for a recent fully performed BPR run (FPR) or current BPR run. The method further involves () building a feature vector matrix (FVM) using RSD. FVM contains feature vectors representing statistical measures of wavelet coefficients determined for variables (v, . . . , v). A projection () is formed by projecting feature vectors onto at least one MSM or a combined multivariate statistical model (CMSM). CMSM is a weighted average of at least two MSMs. Subsequently, at least one estimate is generated for FPRor current BPR run using information provided by the projection ().
