PROBFAIL

Description: Returns the probability of failure at the specified time.

Syntax: PROBFAIL(Data_Src, Mission End Time)

Data_Src is the source diagram from which the data are taken.
Mission End Time is the time that you want to see what is the probability of failure.

Remarks:

The Data_Src can be one of the following values:

If using a default data source, it must be either 1, 2, 3 or 4, as selected from the Data Source Index drop-down list.
It can take a diagram name (e.g., "RBD!RBD1").
It can take a variable name defined via the Defined Names window (e.g., datasource).

The Mission End Time value must be greater than 0.
The value returned by this function is affected by your choice in the Report folio model field on the Analysis Settings page of the diagram control panel.

Example:

PROBFAIL("RBD!RBD1", 500) = 0.3421

Note that this value will vary depending on the source diagram.
