一个分布式产品数据管理系统的研究与开发

RESEARCH AND DEVELOPMENT OF A DISTRIBUTED PRODUCT DATA MANAGEMENT SYSTEM

ＰＤＭ（产品数据管理）系统是支持实现ＣＩＭＳ和ＣＥ（并行工程）的数据集成的重要平台．文中介绍了一个分布式ＰＤＭ系统——ＭＰＤＭ．ＭＰＤＭ是基于多Ｃｌｉｅｎｔ／多Ｓｅｒｖｅｒ结构的，采用了多线程调度、面向对象工程数据库管理策略等一系列当代先进软件技术．此外，ＭＰＤＭ使用了根据ＩＳＯＴＣ１８４／ＳＣ４开发的方法所建立的基于ＳＴＥＰ的产品模型以实现对产品相关过程和数据的一致性管理．

Product data management (PDM) system plays a critical role in the integration of a multiple application system in heterogeneous disciplines,especially in the implementation of CIMS and CE.Here introduced is a distributed PDM system——MPDM, which is based on the architecture of multi client/multi server and takes advantage of many advanced software technologies.In order to manage the product processes and data,MPDM uses the STEP based product model constructed according to the methodology developed by ISO TC184/SC4.
