Bound on Time at Probability of Failure

Description: Returns the 1-sided bound at the specified confidence level on the time corresponding to the specified probability of failure.

Note: 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.

Field Format: [BOUNDTIMEATPROB(Source Number)(Probability of Failure; Confidence Level)]

Source Number is the associated data source number.
Probability of Failure is the unreliability value in question.
Confidence Level is the percentage (entered as a decimal value) for the 1-sided confidence bounds.

Remarks:

The Source Number is selected from the Data Source Index drop-down list.

The Probability of Failure and Confidence Level values must be greater than 0 and less than 1.
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:

[BOUNDTIMEATPROB(1)(0.25;0.9)]
