Why we use Computer Models?

• To spend costs and time by testing a system.

• To train people how to use the system in a safe controlled environment.

• To make predictions of how the system would operate in the future.

• To investigate the capabilities of the system in detail by interrogating.

All are the type of modelling application, except
