A Process Model for Evolutionary Design Case Adaptation

One of the unresolved issues in case-based design is how to perform design case adaptation when the constraints are not numerical. In this paper we present a method of case adaptation that employs an evolutionary algorithm. We present a process model for evolutionary design case adaptation, as well as the knowledge it requires and its implications. This model has been implemented for floor plan layout using a case-base of Frank Lloyd Wright prairie houses and an evaluation using feng shui constraints. The implementation demonstrates the representation issues and shows how the model can address two distinct knowledge sources.
