航天产品可靠性信息的来源多样。可靠性信息的时间性、随机性、有价性、时效性和可追溯性等特征,决定了可靠性数据收集应满足真实性、连续性、完整性等基本要求。同时,对多源信息的收集应遵循先进行需求分析,再确定数据收集点并制定数据收集表格的程序进行。给出了信息的适用性准则和信息分类的三维模型。最后结合具体型号航天产品的可靠性工作的要求,给出了可靠性信息数据库系统的整体方案设计。
Aerospace product reliability information from a variety of sources. Reliability information, such as timeliness, randomness, value, timeliness and traceability, determine the reliability of data collection should meet the authenticity, continuity, completeness and other basic requirements. At the same time, the collection of multi-source information should be followed by the first to conduct needs analysis, and then determine the data collection points and the development of data collection forms of the program. A three-dimensional model of information applicability and information classification is given. Finally, combined with the requirements of the reliability work of specific aerospace products, the overall scheme design of the reliability information database system is given.
