| 摘 要： | 首先建立了面向对象的案例知识表示体系。在此基础上，研究了基于层次分类模型及模糊技术的２级检索策略。基于层次分类模型的检索策略。为大型案例库建立了辅助检索模型。可在案例检索时逐步缩小检索空间，提高诊断效率 ；基于模糊技术的案例检索方法则进一步提高了诊断精度，使系统更具有实用性。

| Abstract: | On the basis of building the object-oriented knowledge representation approach about fault case, the two-level searching strategy on hierarchical classification model and fuzzy technology are studied. The hierarchical classification model can progressively reduce the searching space to improve diagnosis efficiency; the use of fuzzy technology can further improve diagnosis precision. |
