| Abstract: | This paper proposes a method of deep knowledge representation about time logic,introduces the concepts of characteristic attribute,dynamic framework,events and derivale events,offers a method of knowledge reprsentation about events involving time and derivative events which contains the logical time relations between events. The proposed method can be used to establish a real-time fault diagnosis expert system for spacecraft control system.This study is a new research about deep knowledge representation of time-varied systems. |
