摘要
利用粗糙集理论中的粗度概念,在对获取产品设计知识进行扩展性粒度描述的基础上,通过引入知识依赖关系图,构造了n维知识粒度决策空间以及基于多决策类的同构映射决策空间,提出了基于知识依赖关系图和决策空间的决策算法,并结合产品设计中滚动轴承选择决策说明其实用性.
The granularity is used to describe product design knowledge based on the concept of rough degree in rough theory. The knowledge dependent relation diagram is put forward, both the n-dimensional knowledge granularity decision space and the same construction mapping decision space based on multidecision sorts are established, and the decision algorithm is further presented. Finally, by combining with the choice decision of ball bearing the practicability is proved.
