Heterogeneous multigranulation fuzzy rough set-based multiple attribute group decision making with heterogeneous preference information

摘要: Abstract This study proposes a heterogeneous attribute multigranulation fuzzy rough set approach to the problem of multiple group decision-making (MAGDM) under uncertainty. We first present definition multi-source information systems and then construct approximation space using arbitrary binary relation classes generated by different categories attribute. give object with respect space, i.e., model over system. Meanwhile, we investigate some interesting properties conclusions for proposed new also discuss interrelationship between existing generalized models. After that, MAGDM problems based on theory. The procedure methodology as well algorithm method are given detailed comparison traditional methods illustrates advantages limitations. Finally, an example handling evaluation emergency plans unconventional events this approach.
