Abstract: To deal with features of complex product development, the method of concurrent and collaborative design was presented. Firstly, the framework of concurrent and collaborative design based on system theory was established. Within this framework, product design included "time dimension" concurrence and "space dimension" collaboration. Secondly, the expression of concurrent and collaborative model based on constraint network was studied. A general consistency check algorithm was put forward to define the parameter intervals. The method of multidisciplinary design optimization was proposed to obtain optimized solution. Finally, a design example was analyzed to show effectiveness of this proposed method.

Key words: concurrent and collaborative design, constraints network, modeling, design optimization
