SIMULTANEOUS APPLICATION OF MULTIPLE PROCESS CONTROL RULES
<p>Statistical Process Control (SPC) charts are tools used in quality control to monitor and analyze the stability of a process over time. This study evaluates the effectiveness of eight individual Western Electric rules, also known as WECO rules, and the various combinations of these rules with …

Pattern recognition for manufacturing process variation using integrated statistical process control – artificial neural network
Variation in manufacturing process is known to be a major source of poor quality products and variation control is essential in quality improvement. In bivariate cases, which involve two correlated quality variables, the traditional statistical process control (SPC) charts are known to be effective …

New control charts for monitoring univariate autocorrelated processes and high-dimensional profiles
… variance estimators in distribution-free statistical process control (SPC) charts for univariate autocorrelated processes. We introduce two variance estimators---the standardized time series overlapping area estimator and the so-called quick-and-dirty autoregressive estimator---that can be …
