MULTI-WORLD MECHANISM FOR MODELING EVOLUTIONARY DESIGN PROCESS FROM CONCEPTUAL DESIGN TO DETAILED DESIGN

A multi-world mechanism is developed for modeling evolutionary design process from conceptual design to detailed design.In this mechanism,the evolutionary design database is represented by a sequence of worlds corresponding to the design descriptions at different design stages.In each world,only the differences with its ancestor world are recorded.When the design descriptions in one world are changed,these changes are then propagated to its descendant worlds automatically.Case study is conducted to show the effectiveness of this evolutionary design database model.
