The Expert System of Cow Disease Diagnosis Basing on the Uncertainty Evidence Illation

Because of the wide existence of uncertainty evidence in the process of cow disease diagnosis, we established an uncertainty illation model-evidence-weighted uncertainty reasoning model, which is able to deal with the uncertainty. Also, we gave the representation of the uncertainty evidence, the algorithm of transmission, and an illustration of the application of this cow disease diagnosis. This model has well reflected the existence of the uncertainty in the process of the cow disease diagnosis, and reduced the influence of the subjective factor over the diagnosis accuracy.
