Abstract:
The uncertainty
of the domain knowledge in building expert system for diagnosis
is analysed, and a fuzzy diagnostic model, based on fuzzy set
theory, is proposed to deal with the domain knowledge
description and the uncertain reasoning. It was pointed out that
diagnostic weight matrix is the concentrated reflection of the
diagnostic experience of domain experts. Based on the method of
induction learning, the renew algorithm of diagnostic weight
matrix is given to improve the accuracy of diagnostic reasoning.
Key words:
Diagnostic reasoning Uncertainty Fuzzy logic Weight matrix
