文摘

A new multigranulation fuzzy decision-theoretic rough set over two universes was defined. The relationship between the proposed model with the existing decision-theoretic rough set models was established. The three-way decision was deduced based on the multigranulation fuzzy decision-theoretic rough set over two universes. Multigranulation fuzzy decision-theoretic rough set-based three-way group decision making method was established over two universes.
