Abstract: Due to the complicated, multi-level, multi-attribute and creative process of product structure configuration of complex product scheme design, reasonable organization and reuse of design knowledge were guaranteed for improving product design efficiency. Based on multi-level case decomposition, multi-level case-based reasoning and reuse of scheme design knowledge were studied, a formal expression model of hierarchical association and conductivity reasoning for complex product scheme design was presented, conductivity effect function of multi-level reasoning process was established. And then, multi-level case-based reasoning algorithm was put forward and implementation process of initial design scheme was provided. Finally, an example was used to verify the effectiveness and feasibility of the model and algorithm.

Key words: knowledge reuse, scheme design, extension theory, artificial design, case-based reasoning, product design
