On Performance of Two-Parameter Gompertz-Based X¯ Control Charts
Journal of Probability and Statistics, 2020 In this paper, two methods of control chart were proposed to monitor the process based on the two-parameter Gompertz distribution. The proposed methods are the Gompertz Shewhart approach and Gompertz skewness correction method.

PETA KENDALI EWMA RESIDUAL PADA DATA BERAUTOKORELASI
E-Jurnal Matematika, 2019 Control charts with autocorrelation can be overcome by creating control chart with residuals from the best forecasting model. EWMA control chart is a alternative to the Shewhart control chart when detecting small shifts.

Phase I Multivariate Coefficient of Variation Control Charts for High‐Dimensional Processes
Quality and Reliability Engineering International, Volume 42, Issue 5, Page 2314-2327, July 2026.ABSTRACT Multivariate control charts have traditionally focused on monitoring the process mean vector and/or covariance matrix. Recent studies have extended this framework to Phase II monitoring of the multivariate coefficient of variation (MCV); yet very limited work has examined MCV‐based monitoring in Phase I.

A Two Control Limits Double Sampling Control Chart by Optimizing Producer and Customer Risks [PDF]
ITB Journal of Engineering Science, 2010 Standard Shewhart process control chart has been widely used, but it is not sensitive in detecting small shift. A number of alternatives have been proposed to improve the capability of control chart.

Quality and Reliability Engineering International, Volume 42, Issue 4, Page 1691-1706, June 2026.ABSTRACT In modern manufacturing environments, traditional statistical process control (SPC) methods often struggle with complex, dynamic data patterns, particularly when observations are autocorrelated. Control charts are useful tools used in SPC to detect any significant drift in a process.

Fundamental Roles of Visualization in Applied Statistics
Applied Stochastic Models in Business and Industry, Volume 42, Issue 3, May/June 2026.ABSTRACT Graphs and charts have been used for hundreds of years for data visualization, perhaps thousands of years if we count pictographs and symbols in early written languages. Creating these graphs and charts was very time‐consuming when done by hand, and journals and book publishers were reluctant to include them because of the cost.

IEEE Access, 2019 An X-bar control chart using the multiple dependent state (MDS) sampling under indeterminacy is presented in this paper. The MDS sampling utilizes the previous subgroup information if in-decision on the first sample. The use of MDS increases the power of

Medical Physics, Volume 53, Issue 5, May 2026.Abstract Background Statistical Process Control (SPC) has gained increasing interest in radiotherapy Quality Assurance (QA), particularly following recommendations from American Association of Physicists in Medicine Task Group 218. However, SPC is still predominantly applied via univariate charts such as Shewhart and Exponentially Weighted Moving ...
