A mixed control chart for monitoring failure times under accelerated hybrid censoring. [PDF]
J Appl Stat, 2021 In an accelerated hybrid censoring scheme several stress factors can be accelerated to make the products to respond to fail more quickly than under normal operating conditions. In such situations, the control charts available in the literature cover the attribute characteristics only to monitor the performance of the process over time.

Multivariate Mixed EWMA-CUSUM Control Chart for Monitoring the Process Variance-Covariance Matrix [PDF]
IEEE Access, 2019 The dispersion control charts monitor the variability of a process that may increase or decrease. An increase in dispersion parameter implies deterioration in the process for an assignable cause, while a decrease in dispersion indicates an improvement in

Multivariate control chart based on PCA mix for variable and attribute quality characteristics [PDF]
Production and Manufacturing Research: An Open Access Journal, 2018 Two types of control charts exist based on different quality characteristics: variable and attribute. These characteristics are commonly monitored using separate procedures.

A Mixed Control Chart Adapted to the Truncated Life Test Based on the Weibull Distribution
Operations Research and Decisions, 2017 The design of a new mixed attribute control chart adapted to a truncated life test has been presented. It was assumed that the lifetime of a product follows the Weibull distribution and the number of failures was observed using a truncated life test ...

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
