摘　　要：将案例推理技术引入到复杂装备故障诊断系统中,通过检索故障的相似案例对故障进行诊断。具体讨论了基于案例推理的案例表示,探讨了这种基于案例推理的推理过程,最后讨论了相似度定义和基于矢量计算的检索相似案例的算法,从而得到一种对复杂装备故障进行诊断较为行之有效的方法。Case-inferring technology is employed in failure diagnosis system of complicate equipment. The failures are diagnosed through retrieving similar failure cases. Case presentation based on case inferring is discussed concretely. The inferring process based on case inferring is analyzed. Finally, definition of similarity is presented and algorithm to retrieve similar cases based on vector calculation is described in the article, hence a relatively feasible way to diagnose complicate equipment is obtained.
