Constant distribution
A duration that is fixed by design or set somewhere else.
On this page
Shape previewAlways produces the same duration. The horizontal trace represents repeated observations of one fixed duration.
Fixed durationRepeated observations
- fixed duration
- 5 s
- Use when
- A duration that is fixed by design or set somewhere else.
- Avoid when
- Real work varies enough that one exact duration would hide congestion risk.
- Support
- One exact value.
- Parameters
- Set the fixed duration directly.
- Common mistake
- Using a constant because only an average is known; that removes real variability and can understate queues.
- Example
- A timed conveyor step that always takes 5 seconds.
