【摘要】 提出了功能元的概念，并在此基础上提出了一种系统化的功能抽象方法．结合ＩＤＥＦ０方法，这种新的功能抽象方法对功能抽象、数据和知识模型的建立、软件开发具有重要的意义，它不仅适用于ＣＡＰＰ领域，而且对ＣＡＸ等制造信息的功能抽象也具有普遍的指导意义．更多还原

【Abstract】 A new information modeling methodology for manufacturing information system is proposed. A concept of “Function Element (FE)”(or called “Toolcell”) and its relevant methods are of great significance in manufacturing system analysis, function abstraction, data and knowledge model establishment and software development. The proposed analysis and design methodology is not only concerned with CAPP system, but also applicable to the other areas of manufacturing, such as CAX system in manufacturing information generally.更多还原
