Information rough communication based on both-branch fuzzy set

The concept of rough communication based on bothbranch fuzzy set is proposed, in which the loss of information may exist, for each agent there has a different language and can not provide precise communication to each other. The method of information measure in a rough communication based on bothbranch fuzzy set is proposed. By using some concepts, such as |α|-both-branch rough communication cut, the relation theorem between rough communication based on both-branch fuzzy concept and rough communication based on classical concept is obtained. Finally, an example of rough communication based on both-branch fuzzy set is given.
