Research• Main purpose is to understand better• Uncertainty in the assumptions of the model• Key activity: experimental validation
Simulation has a different purpose in research ascompared to development
Development• Model is valid• Main purpose is engineering productivity
• What-if and optimization• Second purpose is international dissemination
of design rules in the company
