Abstract :
In this paper, a method for multi-sensor information fusion based on D-S evidence theory is discussed. An aero-engine gas path component is used as the research object. The information fusion researches are executed on fault information level and information decision level. The effectiveness of the proposed method for comprehensive fault diagnosis of complex system is illustrated by a case study.
