为降低运载火箭集成设计过程数据流建模的复杂度,提出了一种基于标准化接口的数据流二步自动建模方法。该方法采用集成数据字典技术实现运载火箭集成设计各学科领域异构数据的规范化;基于该规范化语义数据,建立了能够准确描述设计活动接口数据交互关系的数据流二步自动建模法;针对数据流建模过程的可行性问题及数据流调度过程的冲突问题,建立了相应的可行性检测及冲突检测准则。扩展传统工作流引擎以构建流程管理系统,并将其应用于某小型三级固体运载火箭集成设计,验证了数据流建模与调度方法的可行性。应用实例表明,该研究成果对解决运载火箭集成设计数据流管理问题具有指导意义。

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.
