Abstract: Based on the theories of case-based reasoning(CBR) and cognitive psychology, the concept of design scenario including problem scenario, solving scenario and solution scenario is proposed to depict industrial design in a cognitive approach and a model of case-based industrial design scenario is built and represented as two main parts: industrial design scenario organization structure and scenario reasoning model. Based on the model, industrial design knowledge from the three aspects of the model is represented and a case-based computer aided design system is built up—CBID which has been put into industrial design practices.

Key words: Case-based reasoning, Design cognition, Design knowledge, Design scenario, Industrial design, NC machine tools
