CAPP系统中工艺决策知识的层次规划

Layer planning of technology decision knowledge in CAPP system

对Hart所提出的知识划分方法进行了系统的分析，指出了它在工艺决策领域中的不适宜性．引入4点基本假设，基于此假设界定了工艺决策知识的4个标准层次．即：知识基元的描述层、关系解释层、控制层、规划层．这种划分方法，明确地界定了各个知识层次．提供了一种可供借鉴的层次化引导框架．

Has systematically analysed the knowledge-deviding method put forward by hart and explained its unworthiness in the field of technology decision. Four basic hypothesis was introduced and based on which the four layers of technology decision knowledge was limited.
