With an animation, people can actually see your simulation model at work. Identifiable elements move through a realistic system. They can observe why problems occur or why one alternative plan is better than another. The ability to see a model in action also makes animation a great verification tool for the model builder. There are some things you can easily see in an animation that would be very hard to catch in the simulation model - like collisions or subtle logic glitches.
Animation enhances the effect of a simulation model.
By combining the visual power of animation with a statistically valid simulation model, you get a complete picture of your system and its behavior. Animate a wide variety of applications Animation gives you a realistic picture of many different kinds of systems. It's easy to see how you can use animation to show cars lining up at a toll booth, or products moving along an assembly line, because objects moving in the real system have direct counterparts moving on the screen. You can also use Proof to animate computer or telecommunications systems in which invisible messages move at very high speeds. Creative use of bar graphs and color changes can effectively depict traffic intensity for those kinds of systems.
