基于面向对象与STEP技术的制造环境模型研究

对制造环境模型的研究是ＣＩＭＳ新的研究领域。将面向对象技术与ＳＴＥＰ技术有机地结合起来，研究制造环境模型。不仅有效地支持基于数据模型的系统体系结构的发展，而且是实现ＣＩＭＳ信息完整而一致的描述与交换的重要基础性工作。

MANUFACTURING ENVIRONMENT MODELLING BASEDON OBJECT-ORIENTED AND STEP TECHNOLOGY

The reserch on manufacturing environment (ME) information inodel is a newfield of CIMS. The inforrnation of ME contains production organization and control struc-ture, nianufacturing resource, and manufacturing capabities of the enterprise. The infor-mation in ME is iategrated resource that sub-system of CIMS need to share in everyphase of the Product. Because there is large amount of inforniation in ME wkich is coin-plex data type. Traditional information modeling methodology can't really describe theinformation of ME. The environment of object-oriented (O-O) tecknology Protides base ofinforniation modeling tkeory and metkod-This paper synthesized STEP and O-O technolo-gy fo establish ME xziodel. It not only supports tle devolopnient of the architectnre thatbases on data model, but alao helps fo standardization of inforniafion exckange and con-sistence o information expression in CIMS.
