This survey presents, in a comprehensive way, the substantial recent developments in the
statistical and economic design of adaptive or dynamic charts that allow some of their …

We review the rapidly growing literature on auxiliary information-based (AIB) process
monitoring methods. Under this approach, there is an assumption that the auxiliary variable …

The usual practice in using a control chart to monitor a process is to take samples of size n
from the process every h hours. This article considers the properties of the X̄ chart when …

A conventional X̄ control chart works in an open loop manner. That is, the process control
engineer waits until the control scheme signals an out-of-control condition. This paper …

Some quality control schemes have been developed when several related quality
characteristics are to be monitored: simultaneous X¯ charts, Hotelling's T2 chart, multivariate …

Standard Shewhart control charts employ fixed sample sizes at equal sampling intervals. By
varying the sample size depending on the current location of the process mean, the mean …

As today's manufacturing firms are moving towards agile manufacturing, quick and
economic on-line statistical process control solutions are in high demand. Multiple sampling …

In crisp run control rules, usually it is stated that a process moves very sharply from in-control
condition to out-of-control act. This causes an increase in both false-alarm rate and control …

When control charts are used for process monitoring, the traditional practice is to take
samples from the process by using a fixed sampling interval (FSI) between samples …

This article proposes a synthetic double sampling chart that integrates the Double Sampling
(DS) chart and the conforming run length chart. The proposed procedure offers performance …
