Process monitoring is regarded as a continuous phenomenon requiring careful
consideration to acquire an enhanced output quality. Dispersion and location are significant …

In this chapter, we provide an up-to-date overview of nonparametric Shewhart-type
univariate control charts. The monitoring schemes incorporated in the present literature …

Improvements in measuring devices, the development of sensing technologies, automated
record-keeping and cloud storage facilities have offered us a large volume of data streams …

We generalize popular distribution-free (nonparametric) Shewhart–Lepage scheme for
simultaneously monitoring of location and scale parameters using an adaptive approach …

Two new distribution-free Lepage-type statistical process monitoring schemes are proposed.
One is the double exponentially weighted moving average Lepage scheme, and the other is …

When using control charts to monitor manufacturing processes, Shewhart control chart is
known to be useful for detecting transient shifts, while the EWMA and CUSUM charts are …

The measurement of daily average customer service times in a service centre holds
paramount importance as it serves as a key metric for assessing service performance and …

With the booming of online shopping, the post-sales online review process becomes a
crucial activity in product life cycle management, as it provides abundant user-generated …

In this paper, we introduce an exactly distribution-free procedure for Phase I analysis which
is capable of assessing stability of both location and scale parameters of the process using a …

This paper proposes a new distribution-free control chart by integrating the powerful
nonparametric two-sample Cramér-von Mises test and the exponentially weighted moving …
