As the aviation system becomes more and more complex, the conventional fault tree analysis (e. g, top-down and bottom-up) techniques, which used to calculate the component importance in the aviation system , is often faced the limitations in terms of the accuracy and efficiency. The Binary Decision Diagram (BDD) method, that can be implemented in the computer efficiently, has the characteristic of the high efficiency calculation and precise result. This paper will talk about the new method or analysis way (BDD) to calculate the component importance in the aviation system instead of the conventional fault tree analysis (FTA) method, in order to improve the aviation systemÂ¿s design and increase the aviation componentÂ¿s reliability.
