并行工程的信息集成框架模型

On the information integrated framework models in concurrent engineering

提出了基于智能数据库支持下的分布式智能化信息集成模型（ＤＩＩＦＭ），以建筑结构设计为例讨论了具体的实现过程，详细研究了多用户并行工作的机制，并以产品数据描述与交换国际标准ＳＴＥＰ和面向对象分析技术为基础建立了并行工程的特征模型。这一模型的提出，对并行工程下开发研究ＣＡＤ系统是有益的探讨。最后，并以已开发出的ＣＩＦＤ雏形为例进行了讨论。

Supported by intelligent database, this paper presents a distributed intelligent information integrated framework model (DIIIFM), which can be used extensively in many fields of science and technology. The application of DIIIFM is discussed in details for the structural design under network with multi users concurrent work mechanism. Thus, this paper is also meaningful for the study of CAD in concurrent engineering. A prototype of concurrent work CAD system is presented.
