摘　　要：在研究基于实例推理(CBR)基本原理和实例特征属性权重的确定方法的基础上,建立了CBR的工艺规划模型,提出了CBR工艺规划算法。根据这种算法,描述了BITCAPP中CBR技术应用的过程,并分析了基于分层递阶思想的实例组织和匹配模型等关键技术。最后以箱体类零件为例对CBR技术在工艺规划中的应用进行了验证。Based on the basic principle of case-based reasoning（CBR） and the determination method of the case feature attribute weight, the CBR process planning model is established and the CBR process planning algorithm is put forward. According to this algorithm, the application process of CBR technology in BITCAPP system is described and the key technology, such as case organization and matching model based on hierarchic ideology is analyzed. In the end, CBR technology is verified in the process planning with taking the box type part as an example.
