Assessing the effectiveness of the ZICOMP-Shewhart control chart for monitoring zero-inflated processes [PDF]

open access: yesScientific Reports
The zero-inflated Conway-Maxwell Poisson (ZICOMP) distribution models count data with many zero observations. This distribution assumes that zero observations occur with probability $$\:p$$ , and the count of nonconformities in a product unit follows the

A comparative analysis of mean charts assuming Weibull and generalized exponential distributions [PDF]

open access: yesHeliyon
This study discusses Shewhart control charts to monitor the mean of non-normally distributed data using extensive Monte Carlo simulations. In particular, Weibull, exponential, and generalized exponential distributions are used to conduct a systematic ...

Comparing the efficacy of coefficient of variation control charts using generalized multiple dependent state sampling with various run-rule control charts [PDF]

open access: yesScientific Reports
This paper aimed to develop a coefficient of variation (CV) control chart utilizing the generalized multiple dependent state (GMDS) sampling approach for CV monitoring. We conducted a comprehensive examination of this designed control chart in comparison

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

Assessing the use of the moving window approaches when monitoring social networks using a degree corrected stochastic block model [PDF]

open access: yesReview of Economics and Political Science, 2021
Purpose – This study aims to assess the effect of updating the Phase I data – to enhance the parameters' estimates – on the control charts' detection power designed to monitor social networks. Design/methodology/approach – A dynamic version of the degree

Optimized repetitive sampling X-bar control chart: performance evaluation and comparison with Shewhart control chart

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
When initial sample information falls short of enabling industrial engineers to confidently make decisions about lot quality assessment, repetitive sampling emerges as a solution.

Max-Half-Mchart: A Simultaneous Control Chart Using a Half-Normal Distribution for Subgroup Observations

open access: yesIEEE Access, 2021
A Simultaneous control chart is a well-known tool for monitoring the process mean and process variability with a single chart. In recent decades, many researchers have been interested in developing simultaneous control charts.

GRAFIK PENGENDALI NON PARAMETRIK EMPIRIK

open access: yesMedia Statistika, 2008
Shewhart control chart is constructed base on the normality assumption of process.  If the normality is fail then the empirical control chart can be an alternative solution.
