Abstract: Design process reengineering was the key part in concurrent engineering which was characterized by decomposition of design process. Axiomatic design methodology provided a theoretical basis for the traditional process decomposition. The framework of independence axiom constructed the functional and structural hierarchies of product by zigzagging mapping between function domain and physical domain. Based on the hierarchy tree of function structure, complete design matrix and flow chart, the design process could be reengineered and the sequence of design tasks could be organized with the consideration of their interactions. Finally, the design process reengineering of the largescale gate valve was provided as an example.

Key words: concurrent engineering, design process reengineering, axiomatic design
