Li and Chen (Cognit Comput. 2018; 10:496–505) proposed the concept of D-intuitionistic hesitant fuzzy set as well a method for comparing two sets. have by introducing degree belief decision maker regarding opinion an expert in existing definition intuitionistic set. In future, other researchers may use Chen’s their research work. However, after deep study, it is observed that fails to different...

An intuitionistic fuzzy set (IFS) is a valuable tool to execute uncertain and indeterminate information. IFSs are more suitable identify decision-maker’s evaluation data in decision-making problems. Intuitionistic aggregation operators (AOs) of enormous consequences multiple attribute group (MAGDM) problems with an environment. Consequently, the main impacts this article are: firstly, instigate...

During the last few years, more and more researchers have been applying IFSs to multi-attribute decision making under various different situations, and a lot of work has been done (Chen and Tan 1994; Hong and Choi 2000; Xu and Yager 2006; Boran et al. 2009; Xu 2010a, c; Zhao 2009; Zhao et al. 2010; Tan and Chen 2010; Wei 2010a; Xu and Xia 2012a; Xu and Cai 2010; Wu and Chen 2011, etc.). The con...

The dynamic multi-attribute decision making problems with intuitionistic fuzzy information are investigated. The notions of intuitionistic fuzzy variable and uncertain intuitionistic fuzzy variable are defined, and two new aggregation operators: dynamic intuitionistic fuzzy weighted averaging (DIFWA) operator and uncertain dynamic intuitionistic fuzzy weighted averaging (UDIFWA) operator are pr...
