A simulation is a computer model that mimics the operation of a real or proposed system, such as the day-to-day operation of a bank, the running of an assembly line in a factory, or the staff assignment of a hospital or call center.
The simulation is time based, and takes into account all the resources and constraints involved, as well as the way these things interact with each other as time passes. Simulation also builds in the randomness you would see in real life.
For example, it doesn't always take exactly 5 minutes for a customer to be served and a customer doesn't always arrive every 15 minutes. This means that the simulation really can match reality, so when you make changes to the simulation it will demonstrate exactly how the system would behave in real life.
With simulation software you can quickly try out your ideas at a fraction of the cost of trying them in the real organization. And, because you can try ideas quickly, you can have many more ideas, and gain many insights, into how to run the organization more effectively.
When you click the run button in a simulation you see the work you do move around the organization. The clock in the corner of the screen tells you what the equivalent time would be in the real system.
Simulation is animated. This enables visualization of a new facility and a greater ability to visualize the impact of experiments in an existing facility. You can see key bottlenecks, over-utilized resources and under resourced elements of a system.
The software automatically collects performance measures as the model runs so that you can not only see visually what will happen, you can also get accurate numerical results to prove your case. .
