• "All models are wrong... Some models are usefulÓ Deming
• Understand, predict, control
• The modeling process

System

• "Any phenomenon, either structural or functional, having at least two separable components and some interaction between these components may be considered a system.Ó Hall, Day
• "The whole is more than the sum of parts.Ó Bertalanffy
• "The features of the complex, compared to those of the elements, appear as "new" or "emergent"Ó Bertalanffy
