Simulation is a quantitative procedure which describes a process by developing a model of that process and then conducting a series of organised trial and error experiments to predict the behaviour of the process over time.
Steps in the Simulation Process
- Define the problem or system you intend to simulate.
- Formulate the model you intend to use.
- Test the model; compare its behaviour with the behaviour of the actual problem environment.
- Identify and collect the data needed to test the model.
- Run the simulation.
- Analyse the results of the simulation and, if desired, change the solution you are evaluating.
- Rerun the simulation to test the new solution.
- Validate the simulation, that is, increase the chances that any inferences you draw about the real situation from running the simulation will be valid.
