Research on Integrated Model and Design Reuse for Development of Complex Product

In order to overcome the heterogeneity of models and support concurrent work, a flexible, multidimensional and integrated model, which stores design information of different engineering domains, is proposed in the paper. The integrated model (DMP) describes design information from three dimensions including the definition of product/component (D), the process of the development (P) and the methodology that the designer adopted (M) in the development of product. Then a workflow which is executed based on DMP model and driven by task and input/output template is proposed for raising work efficiency, reducing producing cost, improving operation level and enhancing enterprise's competitive ability. At last, the framework of design reuse system based on DPM is put forward.
