| Abstract: | Representation of time factor in the knowledge base was analyzed,the time characteristics a- bout knowledge and the time logic relationship of data or events were studied,the concepts of events and derivate events were introduced.Based on the time logic of Allen theory,a method of knowledge repre- sentation about events involving time and derivative events which contained the logical time relations be- tween events were presented.This method can be used to establish a real-time fault diagnosis expert sys- t... |
