of the fault spreading. By applying the modeling method of fuzzy fault Petri nets in fault reasoning and diagnosis, the thought of combining the forward reasoning and backward reasoning was proposed, and corresponding algorithm was given. This method was verified by the example of insufficient pressure of hydraulic system. The results show that the forward reasoning can simulate the process of fault......
