Control charts that are based on assumption (s) of a specific form for the underlying process
distribution are referred to as parametric control charts. There are many applications where …

Signaling in the control charts is usually followed by a substantial amount of delay, in which
precise identification of the time when a change has occurred in a process simplifies the …

This article proposes a CV chart by using the variable sample size and sampling interval
(VSSI) feature to improve the performance of the basic CV chart, for detecting small and …

Non-parametric control charts have been good alternatives to parametric control charts
when little information is known about the type of process distribution or the value of …

In the present paper we provide an up-to-date overview of nonparametric Cumulative Sum
(CUSUM) monitoring schemes. Due to their nonparametric nature, such memory-type …

Distribution-free or nonparametric process control schemes are often preferred over
traditional schemes as these schemes do not require any assumption related to the …

In this paper, we propose a nonparametric group runs control chart using sign statistic for
monitoring the shifts in the process location. Performance of the proposed control chart is …

The conventional cumulative sum (CUSUM) chart is usually designed based on a known
shift size. In usual practice, shift size is often unknown and can be assumed to vary within an …

The CUSUM chart is usually designed based on a known shift size when monitoring the
process mean. In practice, shift size is rarely known but it can be assumed to vary within an …

In statistical process monitoring, it is often assumed that the sequential observations
generated by processes are independent and identically distributed (iid). However, in real …
