Abstract:
A focus of this seminar is on the recently rising interest of big data and the use of multivariate statistical methods for efficient data-driven quality-relevant process monitoring. In this talk, a concurrent projection to latent structures is presented for the monitoring of output-relevant faults that affect the quality and input-relevant process faults. The input and output data spaces are concurrently projected to a latent structure of five subspaces, a joint input-output subspace that captures co-variations between input and output, an output-principal subspace, an output-residual subspace, an input principal subspace, and an input-residual subspace. Appropriate monitoring indices are developed for various fault detection alarms based on these subspaces. The proposed monitoring method offers complete monitoring of faults that happen in the predictable output subspace and the unpredictable output residual subspace, as well as faults that affect the input space only.
