Order statistics in control charts construction
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.

Research on fuzzy control charts for fuzzy multilevel quality characteristics
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 ...

Poisson regression charts for the monitoring of surveillance time series [PDF]
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 ...
