CIMS环境下全局信息建模方法的研究

A methodology for information model level integration in CIMS

计算机集成制造系统 (CIMS)的关键在于信息集成和交换 ,全局信息模型的建立是实现CIMS信息集成与交换的基础。分析了目前在CIMS建模中普遍采用的IDEF方法存在的不足 ,在此基础上 ,提出并介绍了在IDEF建模方法中引入对象实体 ,通过逐级综合信息功能视图建立全局信息模型的方法 ,并已应用于实际的CIMS工程中。

One of the keys to CIMS is information integration and exchange.The global information model of CIMS is essential for information integration and exchange. In this paper, on the basis of analysis of the shortcomings modeled by IDEF method,the modeling method of modified IDEF is proposed and studied and a methodology for developing global information model by integrating CIM information function views is presented,which has been applied to the development of the real system.
