cModel.Bounds Unreliability

Member of: SynthesisAPI9.cModel

Calculates the bounds on the probability of failure at the specified time. Returns a BoundsValues object array that contains the result(s).

You must first use the SetConfidenceLevel method to specify the confidence bound settings, and then use this method to perform the calculations.

Syntax

.Bounds_Unreliability( Time, StartAge, DutyCycle) 

Parameters

Time

Double. The time at which to calculate the probability of failure. (Required)

StartAge

Double. The start age. Default value = 0. (Optional)

DutyCycle

Double. The duty cycle. Default value = 1. (Optional)

Example

VBA

 ... 

 'Add code to get an existing model or create a new one. 
 Dim AModel As New cModel
 ... 
 
 'Set the confidence level to 90% two-sided bounds. 
 Dim ErrorMsg As String
 CallAModel.SetConfidenceLevel(0.9, ConfBoundsSides_TwoSidedBoth, False, ErrorMsg)

 'Calculate the bounds on the model's probability of failure at time = 100. 
 Dim ResultValue As BoundsValues
 Set ResultValue = AModel.Bounds_Unreliability(100)

 'Output sample: Display the results for the upper and lower confidence bounds. 
 MsgBox (" Upper bound: " & ResultValue.Upper & ", Lower bound: " & ResultValue.Lower)
