TSDG: A Qualitative Simulation Method Used in Fault Diagnosis
Fangzhou Bai · Jisuanji gongcheng · 2006
There are a lot of redundancies in the diagnosis result for signed directed graphs use only static symptoms.TSDG method with tem-poral order,based on the graph of five-range qualitative signs,employs the diagnosis of dynamic symptoms and history information of object system.It can search the real fault source in the light of the consistent propagation path of the fault information.The system of SDG based on temporal order can simplify the diagnostic space because it restricts the cause-effect relationship of diagnosis.Using in diagnosing a ductwork with heater equipment,TSDG proves its validity.
