Abstract

A control chart based on functional data (FD) has been proposed to be used as a tool for detecting anomalies and for assessing the trend of daily PM10. In this study, the capability of the FD control chart is investigated. The performance of the FD control chart is compared to the control charts based on the average (AV) and multivariate (MV) data. Daily PM10 indices for AV control chart are the average values while the indices for the MV and FD control charts are computed based on the Principal Component Analysis (PCA) model. The experimentation is conducted using real PM10 data from the Shah Alam air quality monitoring station located at the west of Peninsular Malaysia to investigate the performance of the control charts. The results of the first stage analysis have shown that the FD control chart outperforms the AV and MV control charts in detecting PM10 anomalies of extreme levels. Using a similar number of principal components, it is also found that the PCA model based on FD is able to capture more information compared to the PCA model based on MV. By means of the operating characteristics (OC) curve, the results from the subsequent analysis also reveal that the FD control chart is more sensitive to the changes in the control limits. Overall, the study results have indicated that the FD control chart is worth pursuing.
