为了解决航天产品生产过程中信息孤岛问题，实现各信息系统间的信息共享，保证数据源的唯一性，打通产品信息化制造的数据链路，孤立系统的信息集成势在必行。本文从生产实际需求出发，研究PDM、ERP、MES、DNC系统间相互交换的信息模型，分析各个系统间相互交互的数据流，有效地理清各系统的集成关系，给航天产品全生命周期信息化系统集成奠定基础。通过企业集成应用，该集成模型在信息化系统集成中是可行的。%In order to solve information island of the aerospace production process, achieve the information sharing between the various information systems, ensure the uniqueness of the data source, and open product manufacturing information data link, information integration of the isolated systems is imperative. Proceeding from the actual production needs, this paper studies the mutual exchange information model among PDM, ERP, MES, and DNC system, analyzes of the mutual interaction between the various systems of data flow, and effectively clears the integrated relationship of the various systems, laying foundation of the information system integration of aerospace product lifecycle. Through the applications of enterprise integration, the integrated model is proved feasible in the information system integration.
