Abstract: To deal with complex characteristics of multidisciplinary integrated analysis, an integrated design process based on system decomposition technology was presented. Based on this design process and some single disciplinary analysis tools, a hierarchical multidisciplinary integration and management model was constructed and an integrated design tool - Multidisciplinary Design Optimization Framework（MDOF）was developed with Visual C++6.0. With this method, a rocket launch design problem involved in four different subjects was integrated and optimized in MDOF. Meanwhile, MDOF was compared with the Collaborative Optimization （CO） and Multi-Disciplinary Feasible（MDF） methods. The result showed that the proposed design process had better computational capability.
