The Enhanced EWMA Control Chart with Autocorrelation
Jurnal Teknologi, 2014 Control charts are effective tool with regard to improving process quality and productivity, Shewhart control charts are efficiently good at detecting large shifts in a given process but very slow in detecting small and moderate shifts, such problem could be tackled through design of sensitizing rules.

EWMA Chart and Measurement Error [PDF]
Measurement error is a usually met distortion factor in real-world applications that influences the outcome of a process. In this paper, we examine the effect of measurement error on the ability of the EWMA control chart to detect out-of-control ...

A Nonparametric Multivariate Control Chart Based on Data Depth [PDF]
For the design of most multivariate control charts, it is assumed that the observations follow a multivariate normal distribution. In practice, this assumption is rarely satisfied.

Monitoring of the BTA Deep Hole Drilling Process Using Residual Control Charts [PDF]
Deep hole drilling methods are used for producing holes with a high lengthto- diameter ratio, good surface finish and straightness. The process is subject to dynamic disturbances usually classified as either chatter vibration or spiralling. In this work,
