摘要

文章为解决航天器AIT过程中数据集成度低、数据应用不佳等问题,从数据模型构建、数据集成等方向出发,分析了AIT过程数据在产品结构、时间周期、阶段型号3个维度的演变过程,构建了多维数据模型,并开发基于产品结构的多维数据管理系统。该系统以产品结构为核心,对AIT过程数据进行重新组织,定义不同系统间、不同维度数据之间的关联关系,实现了AIT过程全数据的结构化整合,在此基础上生成了AIT过程数据包。
        In view of the poor data integration and the inadequate data application in the AIT process of spacecraft, this paper, by means of the data modeling and the data integration, studies the evolution process of the AIT process data of the product structure, the time cycle and the development stage. A multidimensional data model is constructed, and a multidimensional data management system is developed based on the product structure. The system, with the product structure as the core, restructures the AIT process data by defining the correlations between different systems and data of different dimensions, to realize the structured integration of the whole data of th AIT process. The AIT process data package is then built on this basis.
