基于实例推理的航空模锻工艺设计研究

针对传统航空模锻工艺设计存在过分依赖经验，以及缺乏积累和继承工艺知识的问题，通过对其设计过程的影响因素分析，提出了基于实例推理的航空模锻工艺设计方法。利用层次分析法（AHP）确定了各因素的推理权重；引入相似理论，得出了相似度的求解方式；并设计了以工艺相似系数为核心的实例推理算法。最后，通过实例验证了该方法的可行性和有效性。

Research on the Aviation Die Forging Process Planning with Case- based Reasoning

For the excessive dependence on experts＇ experience and lack of the accumulation and inheriting of process knowledge in the aviation die forging process planning, it analyzes the relative impact factors of the process planning, puts forward a novel process planning approach based on the ease - based reamning （CBR）. Based on analytic hierarchy process （AHP） and similarity theory, it discusses the calculations of each factor weight and similarity degree, proposes algorithm with CBR- based process- similarity. Finally, it demonstrates a case study in detail to show the rationality and validity of the proposed methods.
