Abstract: Design stream line is a product design process management mode based on production stream line. It can improve design efficiency, reduce design waste and decrease time to market. Through comparing the design process with the production process, the semantic model of tasks, personnel and design knowledge in design stream line was established. The relationships between elements and elements of internal were identified by using mapping network of bimodality and single modality. To build and reuse design stream line, the valuable design activities were modularized based on fuzzy clustering method. Aiming at the features of uncertainty, iterative propority and uniqueness of product development process, multi-mode line balance model of design stream line was presented, and a bottleneck identification algorithm based on complex network algorithm was proposed. Combined with an enterprise's actual demand, a prototype system of design stream line was used to verify the feasibility of proposed method.
