In this paper, we discuss what is knowledge for synthesis and how
knowledge is used in synthesis process. Variety of knowledge is crucial in
synthesis process like design. Such variety of knowledge in turn makes it
difficult to collect and integrate knowledge that is the main process of
synthesis. We model synthesis process as integration of knowledge units
called design experiences that is described on different ontologies. We show
a formalization for synthesis theory based on our design process theory in
which a design process is an iterative logical process of abduction and
deduction on design solution, its properties and behaviors, and knowledge on
objects. In our formalization, a unit of knowledge that we call design
experience is a piece of information with objects, knowledge on the objects,
properties on the objects, and ontology to describe these types of
information. Synthesis process is to integrate a set of knowledge units as
follows; (1) collecting design experiences; (2)building a model that can
includes the collected design experiences by integrating ontologies of the
design experiences, and (3) minimizing an element that designers want to find
newness.
