Abstract [en]

A complex system is a system with many components and interconnections, interactions, or interdependencies that are difficult to describe, understand, predict, manage, design, or change. Complex technical systems are characterized by the level of complexity and uncertainty. Uncertainty appears mainly in system behaviors and the ways different aspects of a system change with time. The uncertainty, which can be seen as a direct consequence of the complexity and it increases with the scale and the scope of the system, will normally decrease as we gain insight and knowledge about the system. Engineering design of complex technical systems depends much more heavily on computer simulation than design of smaller and less complex products. The main objectives for simulations is to assist design reasoning by helping to identify unintended and accidental interactions between components and to assess and verify the system in early design stages. The special character of product development and engineering design require that this reasoning process is situated and that the model definitions are based on "systems thinking". This paper elaborates on a formal basis for model-based design reasoning and presents a formal knowledge framework for model-based design reasoning.
