The simultaneous monitoring of both process mean and dispersion, particularly in normal
processes, has garnered significant attention within the field. In this article, we present a new …

In this short note, we prove that the derivation of the required sample size and critical
acceptance value under the normality assumption of the quality characteristic proposed by …

In practice, a hybrid exponentially weighted moving average (HEWMA) control chart for
monitoring the process mean based on the normality assumption. The performance of …

Many applications, especially in the industrial or medical fields, frequently encounter
window-censored alternating renewal process (ARP). Process monitoring for window …

Zaka et al provided a new distribution called the Weighted Power function distribution
(WPFD), which has application in reliability engineering and survival analysis. They used …

The reflected power function distribution (RPFD) has applications in the fields of reliability
engineering and survival analysis. To identify and remove the variation in different reliability …

In many topical applications, the product's quality can be well described in terms of statistical
regression relationships between one or more response and a set of explanatory variables …

Statistical process control basically involves inspecting a random sample of the output from
a process and deciding whether the process is producing products with characteristics that …

This paper presents a study on using memory-type control charts to detect small to moderate
shifts in the process mean, particularly when the underlying distribution deviates from …

In practice, the control charts for monitoring of process mean are based on the normality
assumption. But the performance of the control charts is seriously affected if the process of …
