基于PDM Enablers的飞行器并行设计文档管理模型

Document Management Model of Vehicle Concurrent Design Based on PDM Enablers

传统的产品数据管理(PDM)系统之间没有标准的接口,缺乏互操作性,难以与国际接轨,限制了飞行器并行设计中产品数据交互的范围。Ob jectManagem ent G roup(OMG)发布的产品数据管理使能(PDM Enab lers)规范支持分布式产品数据管理环境并对不同的PDM系统提供了标准接口,能够很好地解决以上问题。该文以PDM Enab lers为依据,采用面向对象的建模方法,首先提出了基于Enab lers的飞行器并行工程环境体系结构;其次建立了基于Enab lers的文档管理模型,并着重对文档的状态变迁及版本管理机制进行研究;最后讨论了支持飞行器并行设计的文档管理信息存储模式。

There is no standard interface among traditional PDM systems, hence, for lack of intercommunion,it is difficult to join them with international systems. Therefore, the mutual exchange of procuct data is restricted in vehicle concurrent design. PDM Enablers specification, issued by Object Management Group（ OMG）, sustains distributed environment of product data management, and provides standard interface for various PDM systems. Thus, the problems above mentioned could be solved beautifully. The paper refers to PDM Enablers specification and adopts the object - oriented modeling method. At first the architecture for concurrent engineering environment is presented based on Enablers. Then document management model is illustrated based on Enablers, and changeable states of document and mechanism of version management are researched emphatically. Finally the information storage mode of document management for supporting the vehicle concurrent design is discussed.
