reasoning method
5.Dynamic Causality Diagram (DCD) is an uncertainty reasoning method proposed by professor Zhang Qin in 1994. The Causality Diagram (CD) which is constituted by experts, thanks to its reasoning capability (forward reasoning, backward reasoning and bi-directional reasoning), can thus diagnose faults in complex system.
8.Baldwin’ Truth Value Reasoning of fuzzy inference, the reasoning(FEP and FMT)method by similarity degree of disturbing fuzzy sets is given, reasoning method of similarity degree disturbing fuzzy sets pointed out ,the relational reappearance is also discussed, and then the conditions satisfying the revival property of the algorithms is given.
