【摘要】 介绍了北约产品数据模型(NPDM)的三层体系结构和EXPRESS数据建模语言,着重分析了NPDM顶层数据模型与产品寿命周期的关系、模型中各模式记录的信息内容和模式之间的关系。依据NPDM思想建立了保障系统顶层数据模型,阐述了模型中各模式记录的信息内容,给出了人力与人员、保障设备和保障设施等保障要素的数据结构,为进一步建立保障系统数据模型的打下了基础。更多还原

【Abstract】 Three-layer architecture of Nato product data model and data modeling language EXPRESS are introduced, the relationship between top-layer data model of NPDM and product life circle and the relationship between information content recorded in each pattern of data model and pattern are analyzed mainly. The top-layer data model of support system is established according to the thinking of NPDM, the information content recorded in each pattern of the model is described, the data structure of support element including manpower and personnel and support equipment and support facilities are put forward, so the basis of the study of support system data model is established.更多还原
