In the ever-evolving field of time series analysis, detecting changes in patterns and
dynamics is paramount for accurate forecasting and meaningful insights. This article …

Anaerobic digestion (AD) is an appropriate process for bio-energy (biogas) production from
waste and wastewater receiving a high level of attention at both academic and industrial …

Statistical Process Control (SPC) has been widely used in industry and services. The SPC
can be applied not only to monitor manufacture processes but also can be applied to the …

Fault monitoring is often employed for the secure functioning of industrial systems. To
assess performance and enhance product quality, statistical process control (SPC) charts …

This study focuses on the development of new one-sided and two one-sided MEWMA charts
for monitoring the mean of a multivariate normal process. The one-sided MEWMA chart …

In this paper, the mean of a process with several quality characteristics is monitored using a
multivariate control chart which is a variable parameter (Vp) chi-square control chart with two …

Maximum multivariate cumulative sum (Max-MCUSUM) is one of the single control charts
proposed for joint monitoring the mean and variability of independent observation. Since …

The multivariate control charts are not only used to monitor the mean vector but also can be
used to monitor the covariance matrix. The multivariate variability charts are used to …

Early detection of small-magnitude faults in anaerobic digestion (AD) processes is a
mandatory step for preventing serious consequence in the future. Since volatile fatty acids …

Control charts are widely used in industrial environments for the simultaneous or separate
monitoring of the process mean and process variability. The Max‐Mchart is a multivariate …
