Abstract: This paper proposes a new model for grid resource management by employing fuzzy concept lattice and fuzzy concept trie and combines FCA(Formal Concept Analysis) theory with grid resource management technology. The formal concept definitions of grid and resource are given and the fuzzy concept lattice for the grid resources is constructed. The extent trie and intent trie of fuzzy concepts for the grid resources are created and the algorithms are developed for trie creation and retrieval to resources and services by FCA methods. Experiments and application examples show that the method of resource organization is feasible and effective.

Key words: Grid resource model, Formal concept analysis (FCA), Fuzzy lattice, Fuzzy extent trie, Fuzzy intent trie

摘要： 提出了模糊概念格和模糊概念Trie树的网格资源模型，将形式概念分析理论和网格资源管理技术进行了有机地结合。给出了网格、资源的形式概念定义，构造了网格资源模糊概念格。利用形式概念分析方法，生成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。实验和实例表明，这种资源组织方式是可行和有效的。
