| Abstract: | A diagnostic reasoning mode based on causal network is proposed. In this model, the representation of the domain knowledge of diagnostic object by causal network not only shows the uncertainty of knowledge, but also solves the problem of the incompleteness of knowledge. The reasoning procedure is divided into two steps, the recognition of the environment set which is domain-dependent and the generation of diagnostic solution which is domain-independent. The algorithm is thus more flexible and general. |
