PETA KENDALI X DENGAN UKURAN SAMPEL DAN INTERVAL PENGAMBILAN SAMPEL YANG BERVARIASI
Jurnal Teknik Industri, 2000 Shewhart X chart is widely used in statistical process control for monitoring variable data and has shown good performance in detecting large mean shift but less sensitive in detecting moderate to small process shift.

Control chart limits based on true process capability with consideration of measurement system error
International Journal of Metrology and Quality Engineering, 2016 Shewhart X̅ and R control charts and process capability indices, proven to be effective tools in statistical process control are widely used under the assumption that the measurement system is free from errors.

Power functions of the Shewhart control chart
Journal of Physics: Conference Series, 2013 The Shewhart control chart is used to check for a lack of control (a shift in the process). However it is insensitive to small shifts. To increase the sensitivity of the Shewhart control chart, some actions can be taken. These include reducing the width of the control limits, increasing the subgroup size to reduce the variance of the sample mean and ...

Estimation in Shewhart control charts
, 2000 The influence of the estimation of parameters in Shewhart control charts is investigated. It is shown by simulation and asymptotics that (very) large sample sizes are needed to accurately determine control charts if estimators are plugged in. Correction terms are developed to get accurate control limits for common sample sizes in the in-control ...

SYSTEM DESIGN AND BEHAVIOR OF PATTERN RECOGNITION OF CONTROL CHART USING NEURAL NETWORK
Jurnal Teknik Industri, 2003 Recognition of unnatural patterns in control charts is important to get more understanding about the process problem. Shewhart control chart can recognize shift pattern only, while the others cannot be detected by this chart.
