摘要
在分析了现有模糊图论结构的基础上 ,对模糊超图和模糊有向图进行扩充 ,提出一种新的图论结构——模糊元图 ,并将其应用于飞行器故障诊断中的模糊知识库构造。实际应用表明 ,基于模糊元图的知识库具有很高的推理效率 ,并且便于规则的添加和删除。
Based on the analysis of existing fuzzy graph theoretic constructs, a new graph theoretic construct, fuzzy metagraph, is presented. This construction combines and expends fuzzy hypergraph and fuzzy directed graph. In the expert system of fault diagnosis for aircraft, fuzzy metagraph is applied in constructing fuzzy knowledge base. The application results indicate that the knowledge base based on fuzzy metagraph posseses high efficiency of inference and convenience to add or delete a rule.
