【Abstract】 With the aid of the routing methodology in the large scale integration (LSI), an intelligent routing algorithm for the power system graph is presented. And a production system is proposed to describe the routing problem in terms of the characteristics and drawing criterions of power system graph. Based on the knowledge and experience of the experts, a series of reasoning strategies and their optimal combinations are constructed. The experimental results are presented to verify the high drawing quality and high automatic drawing efficiency. Meanwhile, this system is proved to be more intelligent.更多还原
