Linear profile monitoring using EWMA structure under ranked set schemes
(
Springer London
, 2017 , Article)
In many manufacturing processes, study variable is not the only quality characteristic, but there may exist some explanatory variable(s) that are associated with the study variable. This association may be linear or nonlinear ...
Mixed EWMA-CUSUM and mixed CUSUM-EWMA modified control charts for monitoring first order autoregressive processes
(
Taylor and Francis Ltd.
, 2017 , Article)
In practice most processes are known to produce autocorrelated observations. Autocorrelation degrades the performance of control charts by producing frequent false alarms when the process is stable or makes the charts ...
An enhanced nonparametric EWMA sign control chart using sequential mechanism
(
Public Library of Science
, 2019 , Article)
Control charts play a significant role to monitor the performance of a process. Nonparametric control charts are helpful when the probability model of the process output is not known. In such cases, the sampling mechanism ...
On Model Selection for Autocorrelated Processes in Statistical Process Control
(
John Wiley and Sons Ltd
, 2017 , Article)
Using traditional control charts to monitor autocorrelated processes is not beneficial, because it will lead us to misleading detections in the processes. One of the methods used to deal with the control charts for ...
Phase II monitoring of linear profiles with random explanatory variable under Bayesian framework
(
Elsevier
, 2019 , Article)
Linear profiles monitoring have been successfully implemented in many industrial applications. The design structures of control charts for profiles monitoring are mostly based on two major classifications namely Classical ...
On designing efficient memory-type charts using multiple auxiliary-information
(
Taylor and Francis Ltd.
, 2023 , Article)
This article intends to investigate new progressive mean (MEP) charts using a single auxiliary characteristic (AMEP) and two auxiliary characteristics (TAMEP) to trace small shifts in the process mean effectively. The ...
