Degree Dominance-based RSM in SIIFDS
A degree dominance relation is introduced to dominance set-valued interval intuitionistic fuzzy decision systems, and a degree dominance set-valued rough set model (RSM) is established, which is mainly based on replacing the indiscerni-bility relation in conventional rough set theory with the degree dominance set-valued relation. Then, to simplify knowledge representation, we propose two attribute reductions of the degree dominance set-valued interval intuitionistic fuzzy decision systems that eliminate the redundant condition attributes that are not essential from the viewpoint of degree dominance set-valued interval intuitionistic fuzzy decision rules. These results will be helpful for decisionmaking analysis in dominance set-valued interval intuitionistic fuzzy decision systems.
