基于黑板结构建立了 CAPP专家系统 ,应用面向对象技术构造了支持 CAPP决策过程中的黑板结构处理模型、知识源结构模型和适时响应黑板变化的控制模型 ,为用户提供了一个简易、友好的 CAPP专家系统平台 .此系统是以统一数据模型驱动进行决策的 .在控制决策中 ,采用不精确推理算法 ,使决策过程快速而准确 ,并初步得到验证 Based on the blackboard structure, a CAPP expert system is established. The blackboard structure processing model, the knowledge source structure model and the control model which respond to the change of blackboard in CAPP decision-making process are constructed based on object-oriented technology, which provides the user with a simple and friendly CAPP expert System platform.This system is driven by a unified data model for decision-making.In the control decision-making, the inaccurate reasoning algorithm is adopted to make the decision-making process fast and accurate, and preliminary verification
