Order statistics in control charts construction
Acta Universitatis Lodziensis. Folia Oeconomica, 2016 Order statistics are applied in construction of control charts that are used in statistical process control. Control charts monitor the average process level, volatility or extreme values: maximum and minimum.

A Fuzzy EWMA Attribute Control Chart to Monitor Process Mean
Information, 2018 Conventional control charts are one of the most important techniques in statistical process control which are used to assess the performance of processes to see whether they are in- or out-of-control.

Poisson regression charts for the monitoring of surveillance time series [PDF]
, 2006 This paper presents a Poisson control chart for monitoring time series of counts typically arising in the surveillance of infectious diseases. The in-control mean is assumed to be time-varying and linear on the log-scale with intercept and seasonal ...

Fuzzy Approach to Statistical Control Charts
Journal of Applied Mathematics, 2013 After investigating the advantages and disadvantages of current methods of statistical process control, it becomes important to overcome the disadvantages and then use the advantages to improve a method for monitoring a process with categorical ...

Research on fuzzy control charts for fuzzy multilevel quality characteristics
International Journal of Metrology and Quality Engineering, 2021 Fuzzy control charts are proposed to solve the problem that traditional control charts cannot be applied to fuzzy quality characteristics. First, fuzzy quality characteristics are converted to representative statistics, which are fuzzy mode ...

Robust kernel distance multivariate control chart using support vector principles [PDF]
, 2012 It is important to monitor manufacturing processes in order to improve product quality and reduce production cost. Statistical Process Control (SPC) is the most commonly used method for process monitoring, in particular making distinctions between ...
