Abstract: To reduce the modeling complexity of data flow in launch vehicle integrated design, the two-step automatic modeling strategy based on unified interface data was proposed. By using integrated data dictionary technology, the standardization of each course's isomerous data in launch vehicle integrated design was realized. Based on this standardized semantic data, the two-step automatic modeling strategy of data flow was set up, which was used to describe the data interactions among workflow activities. Aiming at the feasibility of data flow modeling and the conflicts during data flow scheduling, the criteria for feasibility checking and conflict checking were proposed. Traditional workflow engine was extended to establish the process management system, and applied the system in designing a three-stage solid rocket launch vehicle. Thus the feasibility of the data flow modeling and scheduling method was proved. Application examples demonstrated that the proposed method played a guiding role in solving the problem of data flow management in launch vehicle integrated design.
