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

Estimation in Shewhart control charts [PDF]
, 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.

CONTROL CHARTS MONITORING FOR QUALITY CONCRETE PAVEMENTS [PDF]
Scientific 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
