Robust economic-statistical design of the EWMA-R control charts for phase II linear profile monitoring

Control charts are powerful tools to monitor quality characteristics of services or production processes. However, in some processes, the performance of process or product cannot be controlled by monitoring a characteristic; instead, they require to be controlled by a function that usually refers as a profile. This study suggests employing exponentially weighted moving average (EWMA) and range ...

Operating charts for continuous sedimentation II: step responses

Abstract. The process of continuous sedimentation of particles in a liquid has often been predicted by means of operating charts and mass-balance considerations, where the underlying constitutive assumption is the one by Kynch. Much more complex operating charts (concentration-flux diagrams) can be obtained from a onedimensional model of an ideal continuous clarifier-thickener unit. The enginee...

EXIT Charts

With wide applications of Turbo Principle in communications engineering, the EXIT Charts (Extrinsic Information Transfer Charts) has been a powerful tool to visualize the convergence behavior of iterative decoding process based on mutual information. Within this report, an introduction to EXIT Charts, its background, properties and applications are presented to allow the audience be familiar wi...

MINDCUMIN charts

A serious drawback of classical control charts is their high sensitivity to deviations from normality. By now, many alternative procedures, often of a nonparametric nature, have been proposed. A danger with these competitors is that unrealistically large Phase I samples might be needed. This can be avoided by using groups of, rather than individual (IND), observations during Phase II. A recentl...
