Information fusion in multi-source fuzzy information system with same structure

With the arrival of the information age, information fusion technology have become more and more important in the field of information service. The main goal of information fusion is to combine different sources information to obtain a single composite of the potential comparable alterative solutions. Multiple information sources can forms an information box if they have same structure, namely, there are same object set and same attribute set. The information fusion is a process from an information box to an information table. In this paper, we proposed two approaches for fuzzy information fusion in multi-source environment with same structure. Furthermore, a case about expert evaluation are carried out to verify the proposed fusion ways and using the fuzzy rough accuracy to test the fusion approaches.
