Simulation involves designing a model of a system and carrying out experiments on it as it progresses through time. Models enable you to see how a real-world activity will perform under different conditions and test various hypotheses at a fraction of the cost of performing the actual activity. One of the principal benefits of a model is that you can begin with a simple approximation of a process and gradually refine the model as your understanding of the process improves. This “step- wise refinement” enables you to achieve good approximations of very complex problems surprisingly quickly. As you add refinements, the model more closely imitates the real-life process.
