Research on modeling technology for dynamic modular design

Modular design is a dynamic process and obtains rational architecture of product family continuously. It needs modeling technology to prepare skeleton for evolution of product system, and adapt to the dynamic characteristic. In this paper, a joint modeling technique is proposed to prepare for evolution of product system, which considers design process as one part of the product system. According to close-loop process of modular design, modeling techniques are analysed and a joint modeling approach is advanced. By comparing interface propagation with network, correlative information is organized in the form of network, and it is collected into a tri-view model. Then collaborative model is given by modular layouts and model of product family is established. In this way, a two-way channel for application and optimization of modular scheme is taken shape. Finally, a case is presented to illustrate the application of this approach, which proved the effectiveness of this approach.
