摘　　要：焊接专家系统以传统的产生式系统的开发最为普遍，但存在着很多缺点。提出了一种ＣＢＲ和ＲＢＲ的混合推理机制，并将其应用于点焊工艺设计。结果证明，ＣＢＲ与ＲＢＲ的结合可以有效的克服单一ＲＢＲ的推理效率低，知识获取困难等缺点，从而显著地提高系统的性能。详细介绍了系统的结构，设计思想和推理机制。Up to now the production systems are most popular in welding expert systems (ES), but many drawbacks of single production system affect their application. A hybrid architecture combining case-based reasoning (CBR) and rule-based reasoning (RBR) is proposed and used in a spot welding processes design ES. The results show that combining CBR and RBR can overcome effectively the drawbacks of single RBR, such as low inference efficiency, knowledge acquirement bottleneck, etc. So the properties of ES are enhanced. The architecture, design philosophy, and inference mechanism are introduced in detail.
