In this paper, we compare a performance of principal component analysis(PCA) and independent component analysis (ICA) process monitoring which are multivariate process monitoring technique. ICA monitoring which is recently developed has been evaluated by compared with PCA monitoring. However there is only simple case to evaluate a performance of these monitoring in the many researches. It is not covered with many cases which can occur in diverse processes. In this paper, the monitoring performance is compared with applications to various simulations. The results of simulation present that these monitorings have a different preference according to process situations.
