Statistical quality control is a very useful tool in the hands of business in order to improve
their products quality. The control charts are the most widely used and the most effective tool …

In this paper we study the problem of content-based image retrieval. In this problem, the
most popular performance measure is the top precision measure, and the most important …

Traditional process monitoring control charts (CCs) focused on sampling methods using
fixed sampling intervals (FSI s). The variable sampling intervals (VSI s) scheme is receiving …

This article compares the effectiveness and robustness of nine typical control charts for
monitoring both process mean and variance, including the most effective optimal and …

The notion of variable warning limits is proposed for variable sample size and sampling
interval (VSSI) charts. The basic purpose is to lower down the frequency of switches …

In this work, we introduce and study one-sided variable sampling interval S control charts
supplemented with signalling and switching rules based on runs. The proposed control …

Variable sample size and sampling interval (VSSI) charts are substantially more efficient
than are the static charts. However, the frequent switches between sample sizes and …

The most common charting procedure used for monitoring the variance of the distribution of
a quality characteristic is the S control chart. As a Shewhart-type control chart, it is relatively …

This article proposes an integrated scheme (T&TCUSUM chart) which combines a Shewhart
T chart and a TCUSUM chart (a CUSUM‐type T chart) to monitor the time interval T between …

The use of runs rules is proposed for switching between the sampling interval lengths of
variable sampling interval Hotelling's T2 charts. The purpose of applying these rules is to …
