Study on Reasoning Mechanism with Uncertain Evidence Caused by Dual-factor Method Used in the Disease Diagnostic System of Ocean Fishes
Chao Tu · Journal of Guangdong Ocean University · 2008
By providing the reasoning mechanism with uncertain evidence based on sufficient factors, necessary factors and confidence factors (regulation intensity), this paper analyses the concerning problems of it. The method can indicate the rules of the diagnosis system of complicated relationships between the conditions, and according to the conditions in the rules, the uncertain factors of rules can be obtained by calculating numbers; It has been applied to the developed expert system of ocean fish disease, successfully showing the uncertainty in the disease diagnosis, and thus efficiently reducing the bad impact on diagnosis by people’s subjectiveness.
