| Abstract: | The request of information fusion in machinery diagnosis is introduced. The general fusion process based on D-S theory in diagnosis is described. And how to solve the problems of quantitative representation and inference under uncertainty by D-S theory is discussed. Based on the construct and function analysis of the machine, a diagnosis tree can be constructed. So a inference diagnosis strategy and decision rule based on the knowledge and diagnosis tree model using the D-S combination rule are proposed. Then it is validated to be quick and efficient diagnosis with the knowledge-based system. |
