We introduct a representation scheme for engineering design synthesis that includes not only a way to represent an evolving attifact but also the design process. The representation uses an object-oriented approach in order to model a wide range of design tasks, including non-routine and novel combinations of design objects (or building blocks ) from the knowledge base. Methods that are applied to design objects represent design operators, and for its design process. The proposed representation is both generic and flexible enough to model many different design processes including the top-down functional decomposition, step-wise refinement, product-oriented bottom-up model, and constraint propagation approaches. We present this model within the framework of a conceptual design support system that was developed as a part of a computer collaborative engineering effort.
