Diagnosis efficiency of disease diagnosis expert system is affected by its bottleneck of knowledge-rule-explosion and invalid combinations which are built on the base of production rule. In order to help doctors diagnose disease, the theoretical model of disease-resemblance pattern recognition based on certainty factors vectors and fuzzy membership factors vectors, its data structure model, its computer model recognition algorithm and its practice methods are proposed. Experimental data shows that compared with the individual human expert, the model can obtain higher diagnostic accuracy rate of 80%, effectively reduce the misdiagnosis rate, and carry a preferential-comprehensive diagnosis performance.
