Abstract:

We are concerned about the quality of a product or performance of a system (e.g., operation of a hospital) on a daily basis. To address these concerns, control charts in statistical process control (SPC) provide a major tool. The conventional control charts, such as the Shewhart, CUSUM and EWMA charts, were developed about half a century ago or even earlier, and require many assumptions on the observed data. Their results are usually unreliable in practice because their assumptions can hardly be satisfied, although these charts are routinely used in many surveillance or quality control systems. In this talk, we will demonstrate these facts using some examples, and provide an overview of recent methodologies available in the literature that might be more appropriate to use.  We will also briefly introduce some recent SPC methodologies for disease screening and disease surveillance.
