摘要： 针对企业信息化中信息系统规划(ISP)在较大程度上依赖先前规划经验和知识的特点，为有效支持ISP知识重用和管理创新，将案例推理技术应用于ISP知识重用的全过程，提出基于案例推理的ISP知识重用方法(HRMKGANNA)，研究应用框架、案例表示、案例检索算法与重用等关键技术。通过组织案例库进行ISP知识检索实验，结果表明HRMKGANNA法具有良好的准确性和较高的效率。

Abstract: Information System Planning(ISP) of enterprises mostly depends on previous knowledge and experience. In order to effectively support ISP knowledge reuse and management innovation, this paper uses the CaseBased Reasoning(CBR) technology to the whole process of ISP knowledge reuse and proposes a casebased knowledge reuse method for ISP: Hybrid Retrieval Method combining KnowledgeGuided Approach with NearestNeighbor Approach(HRMKGANNA) method. The application framework, case representation, case retrieval algorithm and case reuse are thoroughly explored. After organizing the cases base, the ISP knowledge retrieval experiment is conducted, and experimental results demonstrate that HRMKGANNA can satisfy retrieval requirements with high retrieval accuracy and efficiency.

Key words: CaseBased Reasoning(CBR), Information System Planning(ISP), knowledge reuse, case representation
