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.

The Expected Average Run Length of the EWMA Median Chart with Estimated Process Parameters
Austrian Journal of Statistics, 2020 The performance of a control chart is commonly investigated based on the assumption of known process parameters. Nevertheless, in most manufacturing and service applications, the process parameters are usually unknown to practitioners.

Comparison of control charts for monitoring clinical performance using binary data. [PDF]
, 2017 BACKGROUND: Time series charts are increasingly used by clinical teams to monitor their performance, but statistical control charts are not widely used, partly due to uncertainty about which chart to use.

Study on Likelihood-Ratio-Based Multivariate EWMA Control Chart Using Lasso
Kvalita Inovácia Prosperita, 2021 Purpose: When applying exponentially weighted moving average (EWMA) multivariate control charts to multivariate statistical process control, in many cases, only some elements of the controlled parameters change.

Design of a Control Chart Using Extended EWMA Statistic
Technologies, 2018 In the present paper, we propose a control chart based on extended exponentially weighted moving average (EEWMA) statistic to detect a quick shift in the mean. The mean and variance expression of the proposed EEWMA statistic are derived.

Application of EWMA chart for monitoring process mean in paper industry [PDF]
Management Science Letters, 2019 This paper presents a statistical process control (SPC) chart for variables in a new feature for the paper machine in the paper industry. The traditional control charts like X-bar and R charts may be inadequate sometimes when the process exhibits ...

Dispersion chart for some popular distributions under repetitive sampling
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016 A control chart is an important tool of the statistical process control for monitoring deviations from a stable production process. For this purpose different control schemes have been developed for the fast detection of certain changes in the process ...

Triple exponentially weighted moving average control chart with measurement error
Scientific Reports, 2023 Measurement error (M.E) can have a substantial impact on quality control applications, diminishing the sensitivity to detect changes in the mean or variance of quality characteristics.
