| Abstract: | This paper discusses the fuzzy Probability Petri Nets(FPPN),which includes fuzzy and proability information.Based on FPPN,the method of fault diagnosis is studied,the probability information is used to solve conflict problems,and search the most probability fault reasons.The fuzzy information is used to solve uncertainty problems and calculate the reliability of diagnosis . And the petrochemistry faults are given to prove the effectiveness of the method proposed in this paper. |
