Most microdevices are usually developed ad hoc, on the basis of engineers’ experience—there is no systematic procedure for developing a microdevice. In this research, as the first step for the systematic design of microdevices, a design problem o

Univariate and multivariate statistical process control (USPC and MSPC) methods have been widely used in process industries for fault detection. However, their practicability and achievable performance are limited due to the assumptions that a contin

Multivariate statistical process control (MSPC) based on principal component analysis (PCA) has been widely used in chemical processes. Recently, the use of independent component analysis (ICA) was proposed to improve monitoring performance. In the p

A chemical process has a large number of measured variables, but it is usually driven by fewer essential variables, which may or may not be measured. Extracting such essential variables and monitoring them will improve the process-monitoring performa

To improve the performance of multivariate statistical process control (MSPC), two advanced methods, moving principal component analysis (MPCA) and DISSIM, have been proposed. In MPCA and DISSIM, an abnormal operation can be detected by monitoring th

Multivariate statistical process control (MSPC) has been widely used for monitoring chemical processes with highly correlated variables. In this work, a novel statistical process monitoring method is proposed based on the idea that a change of operat
