Distribution Control
The Distribution control is used by many different fields. This display-only control provides summary distribution information about the distribution.
When you click the browse button for the distribution control, the Distribution window opens. In this window, you can modify the distribution and supply required parameter values. For more information, see Distribution Parameters and Descriptions.
The information shown by the Distribution control and in the Distribution window varies based on the distribution type. The following table lists the possibilities for each distribution. If the prompts for Failure Rate (FR), MTBF, and Unreliability (F) have been customized in the Data Definition file, the custom prompts are shown in the distribution summary.
Distribution | Usage | Summary Shown by Distribution Control |
|---|---|---|
Constant Time | --- | Constant Time: Duration = # Units< Minutes or Hours |
Exponential | Failure times | Exponential: FR = # |
Maintenance times | Exponential: MTBF = # Units< Minutes or Hours | |
Lognormal | --- | Lognormal: Mu = #, Sigma = # |
Normal | --- | Normal: Mean = #, StdDev = # |
Rayleigh | --- | Rayleigh: Char Life = # |
Time Independent | Failure times | Time Independent: F = # |
Uniform | --- | Uniform: LB = #, UB = # |
Weibull | --- | Weibull: Char Life = #, Shape Fact = #, t0 = # |
