Mixed Exponentially Weighted Moving Average–Cumulative Sum Charts for Process Monitoring
Quality and Reliability Engineering International, 2012The control chart is a very popular tool of statistical process control. It is used to determine the existence of special cause variation to remove it so that the process may be brought in statistical control. Shewhart‐type control charts are sensitive for large disturbances in the process, whereas cumulative sum (CUSUM)–type and exponentially weighted

A mixed GWMA–CUSUM control chart for monitoring the process mean
Communications in Statistics - Theory and Methods, 2017ABSTRACTThe memory-type control charts are widely used in the process and service industries for monitoring the production processes. The reason is their sensitivity to quickly react against the small process disturbances. Recently, a new cumulative sum (CUSUM) chart has been proposed that uses the exponentially weighted moving average (EWMA) statistic,

Journal of Sensory Studies, 2007
ABSTRACT A sensory panel is often used to profile the same type of product with the same set of attributes for many years. We are interested in characterizing the evolution of the performance of such a panel (and its panelists) over time. This article presents a methodology based on a mixed‐model approach that takes into account the evolution of both ...

The use of patient mix‐adjusted control charts to compare in‐hospital costs of care
Health Care Management Science, 1999We introduce a technique for patient mix-adjusting x charts and compared differences between unadjusted and patient mix-adjusted results. Our data came from coronary artery bypass graft (CABG) surgery patients at Baptist Medical Center, Oklahoma City, Oklahoma.

Design and operational charts for complete mixing activated sludge systems
Water Research, 1979Abstract This paper provides charts enabling the derivation of design and operational procedures for an activated sludge waste water treatment system including the final settler. These charts are based on a mathematical model including Monod relationships describing the microbial growth and the substrate removal in the aerator, while sedimentation in

The Intensity of Lateral Mixing in the Atmosphere as Determined From Isentropic Charts*
Bulletin of the American Meteorological Society, 1941Since the inauguration of the analysis of isentropic charts at the Massachusetts Institute of Technology it has been found that certain well-defined properties are exhibited by these charts, the most important of which is the occurrence of well-marked currents of moist air which can be traced in their course across the whole United States and which ...
