1. Time dependent and time independent simulation: In time dependent simulation know the precise time when the event is likely to occur, but incase of time independent simulation it is not important to know the time when the event is occur.
2. Corporate and financial simulations: The corporate and financial simulation is used in corporate planning, especially the financial aspects. The models integrate production, finance, marketing, and other functions.
3. Visual interactive simulation: It uses computer graphic displays to present the consequences of change in the value of input variations in the model.
