THE MIXED UNIVARIATE CONTROL CHART EWMA AND CUSUM FOR FLAVOUR PRODUCTION QUALITY PROCESS MONITORING

open access: yesJurnal Matematika UNAND
A control chart is an important statistical technique used to monitor the average quality of a process or dispersion. Shewhart control chart is used to detect larger disturbances in process parameters.

The Mixed CUSUM-EWMA (MCE) control chart as a new alternative in the monitoring of a manufacturing process

open access: yesBrazilian Journal of Operations & Production Management, 2019
Goal: The objective is to conclude, based on a comparative study, if there is a significant difference in sensitivity between the application of MCE and the individual application of the CUSUM or EWMA chart, i.e., greater sensitivity particularly for cases of lesser magnitude of change.

CONTROL CHARTS MONITORING FOR QUALITY CONCRETE PAVEMENTS [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2020
In this article, Control charts are employed to analyse the strength quality control of ready-mixed concrete for rigid pavement. The results of the study support that CUSUM statistical analysis is more sensitive than the Shewhart control chart. The CUSUM

New Designing Mixed Double Moving Average-Cumulative Sum Control Chart for Detecting Mean Shifts with Symmetrically and Asymmetrically Distributed Observations [PDF]

open access: yes, 2023
Herein, we present a new control chart called the mixed double moving average-cumulative sum control chart (DMA-CUSUM: MDC) used for detecting shifts in the process mean when symmetrically and asymmetrically distributed.

PCA mix‐based Hotelling's T 2 multivariate control charts for intrusion detection system [PDF]

open access: yesIET Information Security, 2021
Abstract Most of the data, which is in the field of network intrusion detection, have the characteristics of a mixture of high‐dimensional datasets of continuous and categorical variables. It easily leads the traditional multivariate control chart to get the error detection results. Hotelling's T

Exponentially weighted moving average-Moving average charts for monitoring the process mean.

open access: yesPLoS ONE, 2020
This research aimed to propose a newly-mixed control chart called the Exponentially Weighted Moving Average-Moving Average Chart (EWMA-MA) to detect the mean change in a process underlying symmetric and asymmetric distributions.
