Abstract:Based on the analysis of existed fuzzy integral theories,the notions of the Choquet upper and lower fuzzy integral and rough interval numbers integral form were proposed; the rough properties of Choquet fuzzy integral and an information fusion method based on rough Choquet fuzzy integral were given.The method can properly carry out the selection and fusion of interval number sensors in multiª²sensor fusion environment in which various disturbance factors exist.The Choquet upper and lower fuzzy integral is the extended form of the classical Choquet one in a sense of roughness, which can deal with the data sources of rough intervals and objects of information systems.The simulated experiments have validated the effectiveness of the method£®
