摘　　要：构筑面向管理决策的智能系统中常存在知识库结构的复杂度和系统效率的平衡问题,为此用描述性逻辑表示面向管理决策的3类4种异构知识.由于描述性逻辑结合了谓词逻辑和面向对象的知识表示,通过基于描述性逻辑的异构知识的统一表示,降低广义知识库的结构复杂性,并基于描述性逻辑的知识表示系统具有有效的推理能力,保证一定的系统效率.这项研究对于对面向管理决策智能系统的知识库构筑具有一定的理论借鉴作用和实际应用价值.There is a conflict between the structural complex of knowledge base and the system efficiency within building an intelligent system about management decision. Characteristics of knowledge representation are analyzed. Description logics are selected to represent three kinds or four sorts heterogeneous knowledge on management decision problem. The structural complex of general knowledge base is reduced by the unification representation of isomeric knowledge based on description logics. Because description logics unions the predict logics and the objectoriented representation, the knowledge representation system based on description logics has efficiently reasoning ability. The conflict between the structural complex of knowledge base and the system efficiency is resolved. The results can be used as a theoretical basis and provide practical value for building a management declsion-oriented intelligent system.
