A fault prediction model based on extension clustering algorithm is put for-ward. In these models, the running status and the diagnostic data are described formalized and modeled by matter ele-ment model. Using the correlation functions of extension theory, the qualitative and quantitative prediction analysis method of the equipments state is studied. Based on these, a rapid prediction of fault states of complex equipment is achieved, and it provides a support to the computer aided design of the equipment fault prediction. An example is provided to prove its feasibility and validity.
