play a central role in the design process for mechatronic systems. The
behaviors and desired (or undesired) interactions of system components fundamentally define favorable (and unfavorable) product properties. The primary challenge in modeling mechatronic systems lies in their
. To the extent that
physical components are interconnected in a
operating functional unit, models of the components must naturally also be expressed in a
domain-independent abstract structure
. Naturally, when creating an abstract model, relevant physical and dynamic properties must be correctly depicted, and the assignment of real component properties to model parameters should remain sufficiently transparent.
