Fuzzy β-covering based (I,T)-fuzzy rough set models and applications to multi-attribute decision-making
TL;DR: This work proposes two novel methodologies to solve MADM problems with evaluation of fuzzy information, which rely on novel and flexible fuzzy rough set models and observes that the optimal selected alternative is the same, which means that these two decision-making methods are reasonable.
Journal ArticleDOI
Novel fuzzy rough set models and corresponding applications to multi-criteria decision-making
TL;DR: This paper applies ( J, S ) -fuzzy rough set models to make decisions with evaluation of fuzzy information and finds that the traditional methods may fail in some practical situations while the proposed method is still valid.
Journal ArticleDOI
On Multicriteria Decision-Making Method Based on a Fuzzy Rough Set Model With Fuzzy $\alpha$ -Neighborhoods
TL;DR: A novel fuzzy neighborhood operator with reflexivity is constructed and a new fuzzy rough set model based on the fuzzy $\alpha$-neighborhood operator is proposed, aimed at decision-making in information systems with real-valued information systems (RVISs).
Journal ArticleDOI
TOPSIS method based on a fuzzy covering approximation space: An application to biological nano-materials selection
Kai Zhang,Jianming Zhan,Yiyu Yao +2 more
TL;DR: A new method for determining objective weights using the first pair of covering-based fuzzy rough set models is revealed and provided to solve the problem of bone transplant replacement materials selection via the TOPSIS method.
Journal ArticleDOI
TOPSIS-WAA method based on a covering-based fuzzy rough set: an application to rating problem
TL;DR: A rating scheme based on a multi-criteria decision-making method in a finite fuzzy covering approximation space and the performance of the TOPSIS-WAA method is verified from the perspectives of the best alternative and the optimal ranking.
