Description: Returns the conditional probability of failure given the specified start and additional times.
Syntax: CONDPROBFAIL_S(Data_Src, Mission Start Time, Mission Add Time, [Confidence Level])
Data_Src is the source diagram for which the conditional probability of failure is calculated.
Mission Start Time and Mission Add Time are the start age and additional operating time duration, respectively, of the period for which the conditional probability of failure is calculated.
Confidence Level is the percentage (entered as a decimal value) for the 1-sided confidence bounds.
Remarks:
The Data_Src can be one of the following values:
A default data source selected from the Data Source Index drop-down list.
A diagram name (e.g., "RBD!RBD1").
A variable name defined via the Defined Names window (e.g., datasource).
The Mission Start Time and Mission Add Time values must be greater than or equal to 0.
Confidence Level is an optional value and, if specified, must be greater than 0 and less than 1. Confidence bounds are available only in cases where all blocks that can fail in the source diagram use models that have Fisher matrix bounds. To have Fisher matrix bounds, a model must have been created by publishing from a data source, such as a Weibull++ or ALTA data sheet, that was calculated using Fisher matrix bounds. Additionally, bounds are not available if the diagram has containers, subdiagrams or mirrored blocks, or if any block uses the cumulative damage model.
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:
CONDPROBFAIL_S("RBD!RBD1", 1000, 1100) = 0.0163
Note that this value will vary depending on the source diagram.
