CModel.Bounds Unreliability

Calculates the bounds on the probability of failure at a specified time for an associated cModel object. Returns a BoundsValues object that represents the confidence bounds.

You must first use the SetConfidenceLevel method to specify the confidence bound settings, and then use this method to perform the calculations. This method applies to published models only. Returns nothing if the calculation is performed on a non-published model.

Syntax
.Bounds_Unreliability( Time, StartAge, DutyCycle)

Parameters
Time
 * Required. Double. The time at which to calculate the probability of failure.

StartAge
 * Optional. Double. The start age. Default value = 0.

DutyCycle
 * Optional. Double. The duty cycle. Default value = 1.

Example
This example assumes that a published model with ID #47 exists in the repository.

VBA AModel cModel MyRepository.Project.SetCurrentProject(1) AModel = MyRepository.Model.GetModel(47) ErrorMsg String AModel.SetConfidenceLevel(0.9, ConfBoundsSides_TwoSidedBoth, False, ErrorMsg) ResultValue BoundsValues ResultValue = AModel.Bounds_Unreliability(100) MsgBox ( & ResultValue.Upper & & ResultValue.Lower)
