| Abstract: | Mulitivalued information systems reflect the uncertainty and incompletion of information. In this paper, by using connection degree of set pairs upper approximation and lower approximation are defined in the system, then decision tables are analyzed in this case, and distribution reduction, assignment reduction are presented. |
