( 1 ) for methodological syncretization of emi and km , existing reference architectures ( ras ) do not clearly reflect the level characteristics of enterprise knowledge and its organization and application modes . ( 2 ) for enterprise knowledge capture and application , existing enterprise modeling methods face the dilemma of how to facilitate friendly collaboration and communication between system analysts / developers and enterprise staffs , and how to help system analysts / developers utilize model knowledge to carry out effective quantitative analysis . ( 3 ) for knowledge re - use , it lacks powerful knowledge repository systems for enterprise model re - use and corresponding mechanisms for knowledge extraction , classification and index 目前国内外关于该方向的研究尚处于起步阶段，有许多问题亟待解决，主要表现在：在企业集成与知识管理的方法论融合方面，现有参考体系结构没有很好地反映出企业知识的层次特征及其组织、应用方式；在企业知识的收集与应用方面，现有企业建模方法在如何促进系统分析设计人员与企业人员进行友好的合作与交流和如何帮助系统分析设计人员利用模型知识进行有效的定量分析这两个问题上存在着矛盾；在知识重用方面，缺乏面向企业模型重用的功能完备的知识库系统及相应的知识提炼和分类检索机制，能够被业界广泛接受的参考模型尚不多见；在建立面向企业集成的基于知识的系统方面，尚没有很好地解决知识的形式化表示问题，缺乏用于描述企业深层知识的形式化建模手段。
