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 ...
A non-parametric double homogeneously weighted moving average control chart under sign statistic
(
John Wiley and Sons Ltd
, 2021 , Article)
In practical situations, the underlying process distribution sometimes deviates from normality and their distribution is partially or completely unknown. In that instance, rather than staying with/depending on the conventional ...
Monitoring multivariate coefficient of variation for high-dimensional processes
(
John Wiley and Sons Ltd
, 2022 , Article)
Multivariate coefficient of variation (MCV) charts are effective tools for monitoring process relative variability. They are developed on the assumption that the process subgroup size available for monitoring the MCV ...
Enhancing the detection ability of control charts in profile monitoring by adding RBF ensemble model
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
While numerous contributions and applications have been extended in profile monitoring, little attention has been paid to employing machine learning techniques in development of control charts. In this paper, a novel control ...
