System of variational inequalities with interconnected obstacles
(
Taylor and Francis
, 2020 , Article)
Our objective with this paper is to discuss multi-switching problems, arising as variational inequalities, that models decision under uncertainty. We prove general existence theory through monotone scheme and discuss ...
New efficient exponentially weighted moving average variability charts based on auxiliary information
(
John Wiley and Sons Ltd
, 2020 , Article)
Control chart is a well-known tool for monitoring the performance of an ongoing process. The variability of a process is an important parameter that may deteriorate the process performance if it is not taken care on time. ...
Efficient bivariate EWMA charts for monitoring process dispersion
(
John Wiley and Sons Ltd
, 2020 , Article)
To ensure high quality standards of a process, the application of control charts to monitor process performance has become a regular routine. Multivariate charts are a preferred choice in the presence of more than one ...
Auxiliary-information-based efficient variability control charts for Phase I of SPC
(
John Wiley and Sons Ltd
, 2020 , Article)
The inclusion of correlated auxiliary variables into the monitoring scheme of quality characteristic of interest has gained notable attention in recent statistical process control (SPC) literature. Several authors have ...
Efficient linear profile schemes for monitoring bivariate correlated processes with applications in the pharmaceutical industry
(
Elsevier
, 2020 , Article)
The complexity of chemical processes warrants that collection of information about the processes will continue as they proceed through the various stages of industrialization. Process monitoring has emerged as an essential ...
On designing an assorted control charting approach to monitor process dispersion: an application to hard-bake process
(
Taylor and Francis Ltd.
, 2020 , Article)
The monitoring of process variability is an important feature to get optimal output from a process. Control charts are vital tools used for efficient process monitoring. The commonly used types of charts include Shewhart, ...
A new hwma dispersion control chart with an application to wind farm data
(
MDPI AG
, 2020 , Article)
Recently, a homogeneously weighted moving average (HWMA) chart has been suggested for the efficient detection of small shifts in the process mean. In this study, we have proposed a new one-sided HWMA chart to effectively ...
An Improved Control Chart for Monitoring Linear Profiles and its Application in Thermal Conductivity
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In most of the manufacturing processes, we encounter different quality characteristics of a product and process. These characteristics can be categorized into two kinds; study variables (variable of interest) and the ...
Efficient control charts for monitoring process CV using auxiliary information
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
Coefficient of variation (CV) control charts are a suitable choice for the monitoring of variation in cases when the process standard deviation is proportional to the process mean. This study is aimed at enhancing the ...
Enhanced remediation of Cr6+ in bacterial-assisted floating wetlands
(
Blackwell Publishing Ltd
, 2020 , Article)
Hexavalent chromium (Cr6+) is reported to have negative effects on fauna and flora. The present study establishes plant-bacterial synergism in floating wetlands (FWs) for the maximum removal of Cr6+ from the contaminated ...
