There are some situations when the process mean fluctuates from time to time but is still
considered as in-control and the process standard deviation is a linear function of the …

Control charting techniques have been applied to a wide variety of areas. In certain areas,
such as in finance and healthcare, the process mean and variance are not independent of …

The coefficient of variation (CV), a measure of relative variability, is an important quality
control issue worthy of consideration in some manufacturing and service-oriented …

In recent years, the coefficient of variation (CV) chart is receiving increasing attention in
quality control. A number of studies demonstrated that adaptive charts could detect process …

Monitoring the coefficient of variation (CV) is of interest when there is a constant proportion
between the varying standard deviation and the varying mean in the process. In a …

Control charts for monitoring the coefficient of variation (CV) have been receiving a lot of
attention in the literature, with numerous more powerful and robust CV charts being …

In industries, multi-variety and small batch processes are extremely common due to the fact
that the production process is moving towards flexible manufacturing to meet the increasing …

Continuous surveillance of the coefficient of variation is a quality control issue worthy of
consideration in several manufacturing and service‐oriented companies. In this paper, we …

In production, it is common to deal with short production runs, where flexibility is required in
the built-up of parts to produce numerous variants of manufactured goods. Monitoring the …

An adaptive control chart is one of the most effective techniques in Statistical Process
Control (SPC). The coefficient of variation (CV) is common in many real life applications …
