Parametric RDA Folio Control Panel Settings

The parametric RDA folio control panel allows you to configure the analysis settings for the data sheet and view/access the results. This topic focuses on the Main page and Analysis page of the parametric RDA folio control panel, which contain most of the tools you will need to perform the analysis. For more information about the control panel in general, see Control Panels

Control Panel Main Page

The GRP model uses the concept of virtual age to mathematically capture the effect of the repairs on the subsequent rate of occurrence of failure (i.e., failure intensity). The rate of occurrence of failure over time is modeled by the power law function. This means that the GRP analysis method has three parameters, two of which are used to describe the power law function and a third for estimating the virtual age of a system.

Folio Tools

The folio tools are arranged on the left side of the Main page of the control panel:

  Calculate estimates the parameters of the GRP model, based on the current data set. This tool is also available by choosing Recurrent Event Data > Analysis > Calculate.

  Plot creates a new sheet in the folio that provides a choice of applicable plot types. In parametric RDA folios, this includes cumulative failures vs. time, failure intensity vs. time, etc. This tool is also available by choosing Recurrent Event Data > Analysis > Plot.

  QCP opens the Quick Calculation Pad, which allows you to calculate results based on the analyzed data sheet, such as the number of failures and mean time between failures (MTBF). This tool is also available by choosing Recurrent Event Data > Analysis > Quick Calculation Pad.

  Change Units opens the Change Units window, which allows you to change the units for the values in the current data sheet.

The following settings are available on the Analysis page of the parametric RDA control panel:
