基于实例的CAPP策略

The Case-Based CAPP Strategy

从充分利用工艺规程编制实例的角度出发，提出了用基于实例的推理改进ＣＡＰＰ推理方法的策略，并具体介绍了将基于实例的推理与基于知识的推理有机结合的混合推理系统的具体结构、实例的表示、提取方法以及基于知识、实事库的正确性维护与版本管理的实例修改策略。

With the viewpoint of fully utilizing process planning cases, the strategy improving CAPP with case-based reasoning is proposed.The structure of the system integrating case based reasoning and generalizedknow ledge based reasoning is presented.And some key techniques are described , which includerepresentation of cases,retrieval of cases and the strategy of case medification based on knowledge,truthmaintenance of the fact bases and design version management.
