A variety of artificial intelligence techniques have been used in attempts to automate design
synthesis tasks. Two common approaches are case-based and decompositional design. While
powerful techniques in their own right, their integration has lead to a new generation of
design synthesis systems capable of tackling a larger range of problems with greater
effectiveness. In this paper previous attempts at integrating these approaches are examined in
a number of design systems. Although significant advances have been made, important
shortcomings still exist. The main focus of this paper is to address the limitations of these
design synthesis models. To this end Déjà Vu, a new hybrid model of design synthesis, has
been developed and is described. Déjà Vu integrates decompositional and case-based
approaches in a framework that exploits the power of experiential knowledge, and benefits
from far greater domain applicability when compared to existing design techniques. Two
implementations of this model, that are targeted at real-world software design tasks, have
yielded encouraging preliminary results and are also described in this paper.
