【摘要】 为了满足不同的企业应用系统对企业模型的需求,提出一种可扩展的企业模型。该模型包括核心层、基本层和扩展层三个层次,核心层描述模型的核心概念,基本层模型综合当前的企业建模方法对核心层模型进行初始扩展,以适应应用系统的共性需求,扩展层模型通过扩展机制,并根据用户需求进行动态扩展。详细论述了每个层次的模型、一致性规则约束下模型的扩展机制和基于扩展方法的建模过程。更多还原

【Abstract】 In order to meet needs of the different enterprise application systems for enterprise models,an extensible enterprise model is presented. This model is divided into three levels:core level,basic level and extension level. The core level model describes the core conceptions of enterprise modeling. The basic level extends the core level on the some current modeling methods to meet the generic needs of application system. The extension level model can build dynamic extension to meet the needs of the different users according to extension mechanism. The every model is discussed in detail. The extension mechanism with consistency rules constraint is provided. The modeling process of this method is specified.更多还原
