The cost cumulant statistical control method optimizes the system performance by shaping the probability density function of the random cost function. For a stochastic system, a typical optimal ...

In this paper, a multivariate monitoring method based on dual control chart (DCC) is proposed. The contributions are as follows: First, deviance variables are explored to reveal the fault information ...

Our regional charts (ERC) are available in 13 areas over Europe in the lower airspace, but also upper airspace. The source of the data used on the chart is EUROCONTROL's European AIS Database (EAD-SDO ...

The three sigma limit is statistical data within three standard deviations from a mean. Three sigma limits set the upper and lower control limits in statistical quality control charts. Data above ...
