Definition
Animation is a dynamic, visual representation of the simulation model’s execution. It is used primarily as a Verification tool to ensure that the model’s logic and flow match the practitioner’s intent.
Why It Matters
Humans are evolutionarily optimized to detect “wrongness” in motion. Skipping animation means missing the “gut-check” that catches subtle logic errors before they become million-dollar mistakes in a real-world system.
Core Concepts
- Visual Logic Check: Identifying obvious errors such as entities moving through solid objects, disappearing unexpectedly, or entering the wrong resource.
- Resource Status Visualization: Using color or shape changes to represent resource states (e.g., Green for Idle, Red for Busy, Yellow for Failed).
- Communication Tool: Helping non-technical stakeholders understand how the model works, thereby increasing Model Credibility.
- Limitation: Animation is not validation. A model can look realistic (Face Validity) while being statistically incorrect.
