Uses
The simulation is a dynamic tool forecast a system evolution and find a solution to get the desired responses.
If the system is easy to solve this kind of analisys can be done in static mode with math model; but if the complexity increase only simulation technique can afford to get a better result and solve the problem.
In industrial field the simulation can be used in all phases of Life Cycle Cost, expecially during flow pre-engineering phase when are defined material and information flow to get the production target.
