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 ...
An improved adaptive EWMA control chart for monitoring time between events with application in health sector
(
John Wiley and Sons Ltd
, 2023 , Article)
Nonconforming events rarely occur in high-quality processes, and the time between events ((Formula presented.)) is likely to be followed by a skewed distribution, such as an exponential distribution. This paper proposes ...
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. ...
Bayesian EWMA control charts based on Exponential and transformed Exponential distributions
(
John Wiley and Sons Ltd
, 2021 , Article)
In this paper, we proposed the Bayesian exponentially weighted moving average (EWMA) control charts for mean under the nonnormal life time distributions. We used the time between events data which follow the Exponential ...
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 ...
Contributing risk factors of common psychiatric disorders in the Pakistani population
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
With an increasing incidence of psychiatric disorders worldwide, there is a need for a better understanding of the population-specific contributing risk factors that are associated with common psychiatric conditions. This ...
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 ...
Employing evolutionary artificial neural network in risk-adjusted monitoring of surgical performance
(
Springer Science and Business Media Deutschland GmbH
, 2023 , Article)
Various applications of control charts in the field of health-care monitoring and surveillance can be found in the literature. As one of the major categories, monitoring binary outcomes of cardiac surgeries with the aim ...
The use of fast initial response features on the homogeneously weighted moving average chart with estimated parameters under the effect of measurement errors
(
John Wiley and Sons Ltd
, 2021 , Article)
Fast initial response (FIR) features are generally used to improve the sensitivity of memory-type control charts by shrinking time-varying control limits in the earlier stage of the monitoring regime. This paper incorporates ...
