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。
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.
