Two approaches to synthesis based on the domain theory

The domain theory is described in this chapter. By a strict distinction between the structural characteristics and the behavioural properties of a mechanical artefact, each domain, i.e. transformation-, organ-, and part domain, becomes a productive view for design of mechanical artefacts. The functional reasoning within each domain and between the domains seems to be ruled by the function-means law (Hubka´s law).

On the basis of the domain theory and the function-means law we present two formal approaches to the synthesis of mechanical artefacts, namely a design-process-oriented approach and an artefact-oriented approach. The design-process-oriented synthesis approach can be seen as a basic design step for composite mechanical artefacts.

The artefact-oriented approach has been utilised for the development of computer-based design support systems.
