就现有的计算机辅助装配顺序规划研究中存在的不足，提出基于事例推理（CBR）的装配顺序规划思路，研究基于CBR的装配顺序规划中的关键技术，开发出产品装配分析原型系统PAAS。系统包含装配数据建模，装配顺序规划和综合DFA分析等功能。结合原型系统实例讲解基于CBR的装配顺序规划的实现方法。
Based on the existing problems in the research of computer aided assembly sequence planning, this paper proposes an assembly sequence planning method based on case-based reasoning (CBR), studies the key technologies in the assembly sequence planning based on CBR, and develops the prototype assembly system PAAS. System includes assembly data modeling, assembly sequence planning and comprehensive DFA analysis and other functions. Combined with the prototype system examples to explain the CBR-based assembly sequence planning methods.
