Building valid, credible, and appropriately detailed simulation models - Techniques for increasing model validity and credibility
3 important questions on Building valid, credible, and appropriately detailed simulation models - Techniques for increasing model validity and credibility
Validation techniques: (Increasing validity, credibility by)
1. Collect high-quality data.
2. Interact with manager on regular basis.
3. Maintain an assumptions document and perform a structured walk-through.
4. Validate components of the model by using quantitative techniques.
5. Validate the output from the overall simulation model.
6. Use animation.
