Abstract In recent years, many kinds of multi-granulation rough set model have developed. Aimed at the dominance relation of set-valued information system which widely exists in practise, the multi-granulation dominance relation rough set model is proposed in this paper. Through the example of data processing, and by the comparison with the existing multi-granulation rough set model, the lower approximation of the multi-granulation dominance relation rough set is more accurate. Finally, the proposed model as a kind of information fusion technology is applied in the problem of target threat assessment. Experimental results show that the proposed model adapts more complex multi-source information environment.
