Early fault intelligent diagnosis of shuttle aircraft structure system

Our early fault intelligent diagnosis is based on fusing D-S (Dempster-Shafer) Evidence Theory with multi-agent module. We present early fault intelligent diagnosis model and the features of the structure of mixed Agent. The D-S fusion reasoning algorithm is also proposed that embody the realization strategy of early fault intelligent diagnosis. Finally we applied our method to early fault intelligent diagnosis of thermal protection system of shuttle aircraft. The results of our diagnosis show preliminarily that our method is a valid and effective way for identifying early fault of thermal protection system of shuttle aircraft.
