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 ...
An Assorted Design for Joint Monitoring of Process Parameters: An Efficient Approach for Fuel Consumption
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Due to high fuel consumption, we face the problem of not only the increased cost, but it also affects greenhouse gas emission. This paper presents an assorted approach for monitoring fuel consumption in trucks with the ...
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 ...
A Multivariate Homogeneously Weighted Moving Average Control Chart
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
This paper presents a multivariate homogeneously weighted moving average (MHWMA) control chart for monitoring a process mean vector. The MHWMA control chart statistic gives a specific weight to the current observation, and ...
Efficient cv control charts based on ranked set sampling
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Monitoring process variability is essential for establishing efficient process-control schemes. In practice, when the mean levels of a parameter are constant, and the process variance (or standard deviation) is independent ...
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 ...
Poisson progressive mean control chart
(
John Wiley and Sons Ltd
, 2017 , Article)
In real life applications, many process-monitoring problems in statistical process control are based on attribute data resulting from quality characteristics that cannot be measured on numerical or quantitative scales. For ...
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 ...
Directionally sensitive homogeneously weighted moving average control charts
(
Wiley
, 2021 , Article)
One-sided control charts for monitoring changes in the mean level are proposed in this paper. The proposed charts are given in the form of a homogeneously weighted moving average technique that provides efficient monitoring ...
Efficient homogeneously weighted dispersion control charts with an application to distillation process
(
Wiley
, 2021 , Article)
Monitoring disturbances in process dispersion using control chart is mostly based on the assumption that the quality characteristic follows normal distribution, which is not the case in many real-life situations. This paper ...
