An interactive evolutionary design system with feature extraction

In order to extraction the product form features, the Web-based feature database system was carried out and the feature cognition space was constructed. The form feature information was analysed and processed through Multidimensional Scaling (MDS), hierarchical clustering and morphological analysis technology. To enhance the efficiency of the automatic conceptual design, the interactive evolutionary design system (IEDS) based on the Orthogonal Interactive Genetic Algorithm (OIGA) in form design was advanced. With this method, the genetic convergence effects are improved and users' fatigues are alleviated by means of simplifying the solution space orthogonally, communizing the fitness evaluation and visualizing the project interface. Example results indicate the improved IEDS was more feasible and reasonable than the simple IEDS.
