Three-Way Fuzzy Sets and Their Applications (II)

Recently, the notion of a three-way fuzzy set is presented, inspired by basic ideas decision and various generalized sets, including lattice-valued partial intuitionistic etc. As new theory uncertainty, it has been used in attribute reduction as control method for water level. However, an extension decision, this not multi-criteria making (MCDM short). Based on previous work, paper, we present rough models based which extend existing both complete incomplete information systems. Furthermore, are to solve issue MCDM. Firstly, relation covering presented Because almost all proposed under information, can be seen supplement these models. Then, relationship between presented. Finally, novel MCDM models, paper defect diagnosis.
