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 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 …

The primary aim of this research is to propose a revised triple sampling (TS) X¯ chart, where
the derivations of new formulae for computing the average run length of the triple sampling …

In many manufacturing or service systems, the product quality and/or process outcome is
described in terms of a large number of quality characteristics. Since the use of large sample …

In recent years, the suitable use of auxiliary information technique in control charts has
shown an improved run length performance compared to control charts that do not have this …

The coefficient of variation (CV) is used in process monitoring when the process mean and
standard deviation are proportional to each other. In this work, a side‐sensitive modified …

Adapted from the acceptance sampling field, the double sampling monitoring schemes
implement a two-stage strategy to decide whether the process being monitored is in-control …

The use of the auxiliary information (AI) method in control charts is gaining increasing
attention. Many studies have shown that auxiliary information-based charts can boost the …

Monitoring production processes to provide potential customers with quality products while
utilising fewer resources and reducing the cost of inspection is a challenge to quality and …

There are numerous academic researches on statistical process monitoring schemes that
assume that sequential observations are independent and identically distributed (iid); …
