摘　　要：在研究总结了现有成果的基础上,首次提出了模糊概念格和模糊概念trie树的网格资源管理策略,将形式概念分析理论和网格资源管理技术进行了有机结合。给出了网格、资源的形式概念定义,建立了网格资源阈值模糊概念格模型。在阈值模糊概念格模型基础上,利用形式概念分析方法构造了网格资源模糊概念的外延trie树和内涵trie树,并给出了树的生成和资源与服务检索算法。实验和应用实例表明,这种资源组织方式是可行的和有效的。This paper first proposed grid resource management strategies by employing fuzzy concept lattice and fuzzy concept trie and combined FCA theory with grid resource management technology based on studing and summarizing existing results. Gave the formal concept definitions of grid and resource, proposed the threshold fuzzy concept lattice model for grid resource. Created the extent trie and intent trie of the grid resource fuzzy concepts and developed the algorithms for trie creation and re- trieval to resources and services base on the threshold fuzzy concept lattice model by FCA methods. Experiments and application examples show that the method of resource organization is feasible and effective.
