In this paper, we provide an overview of a class of control charts called the synthetic charts.
Synthetic charts are a combination of a traditional chart (such as a Shewhart, CUSUM, or …

The coefficient of variation (CV) control chart has recently been introduced in the literature.
Here, the salient features of this chart and the conforming run length chart are integrated to …

Quality control charts have been widely recognized as a potentially powerful statistical
process monitoring tool in statistical process control because of their superior ability in …

Measurement errors often exist in quality control applications. In this paper, the performance
of the synthetic chart is investigated when measurement errors exist using a linearly …

The double sampling (DS) X¯ chart when the process parameters are unknown and have to
be estimated from a reference Phase-I dataset is studied. An expression for the run length …

Conventionally, the standard process monitoring control charts (CC s) focused on fixed
sample size (FSS). An optimal statistical scheme is proposed in this study using a variable …

A statistical quality control chart is widely recognized as a potentially powerful tool that is
frequently used in many manufacturing and service industries to monitor the quality of the …

Recent studies show that the Shewhart median chart is widely used for detecting shifts in a
process, but it is often rather inefficient in detecting small or moderate process shifts. In order …

The quality of a product, based on the number of non-conforming items can be controlled
using the np chart. This paper proposes a synthetic double sampling (DS) np chart which …

The presence of measurement errors can seriously alter the statistical performance of Phase
II control charts. Up today, no research on designing the triple sampling control charts taking …
