This paper presents a new Weibull family of distributions. The compatibility of the newly
developed class is justified through its application in the field of quality control using Weibull …

The exponentially weighted moving average (EWMA) control chart is a popular tool used to
monitor and identify slight unnatural variations in the manufacturing, industrial, and service …

EWMA) control chart is one of the control charts and can be used to quickly detect a small
shift. The performance of control charts can be evaluated with the average run length (ARL) …

The objective of this paper is to study Statistical Process Control (SPC) with a Moving
Average control chart (MA). The main characteristics of a control chart are the Average Run …

Herein, we derive explicit formulas for the average run length (ARL) on an extended
exponentially weighted moving average (EWMA) chart running a seasonal autoregressive …

A modified exponentially weighted moving average (EWMA) scheme is a quality control
chart which can quickly detect small shifts in autocorrelated data. In this article, an explicit …

In this study, we apply the Fredholm-type integral equation method to derive the explicit
formulas of the average run length (ARL) for an autoregressive moving average process …

We study optimal design of the Exponentially Weighted Moving Average (EWMA) chart by a
proper choice of the smoothing factor and the initial value (headstart) of the decision statistic …

Statistical process control (SPC) plays a necessary role in manufacturing industry
processes. An essential tool for SPC used for monitoring, measuring, controlling, and …

In this study, we propose the explicit formula of the average run length (ARL) for the
autoregressive process with a quadratic trend on the modified exponentially weighted …
