Dual Hesitant Pythagorean Fuzzy Hamy Mean Operators in Multiple Attribute Decision Making

Abstract

To fuse the information in dual-hesitant Pythagorean fuzzy sets (DHPFSs) more effectively, in this paper, some dual hesitant Pythagorean fuzzy Hamy mean (DHPFHM) operators, which can consider the relationships between being fused arguments, are defined and studied. Afterward, the defined aggregation operators are used to multiple attribute decision-making (MADM) with dual-hesitant Pythagorean fuzzy elements (DHPFEs), and the MADM decision-making model is developed. In accordance with the defined operators and the built model, the dual-hesitant Pythagorean fuzzy weighted Hamy mean (DHPFWHM) operator and the dual-hesitant Pythagorean fuzzy weighted dual Hamy mean (DHPFWDHM) operator are applied to deal with green supplier selection in supply chain management, and the availability and superiority of the proposed operators are analyzed by comparing with some existing approaches. The method presented in this paper can effectually solve the MADM problems, which the decision-making information is expressed by DHPFEs and the attributes are interactive.

CODAS Method for Multiple Attribute Group Decision Making Under 2-Tuple Linguistic Neutrosophic Environment

“…However, it is difficult to obtain assessment information which is expressed by 2TLNNs, so we need to continue to study this problem. In the future, the 2-tuple linguistic neutrosophic CODAS model can be applied to the risk analysis (Wei et al, 2019h, 2018, the MADM problems (Wei et al, 2019a;He et al, 2019a;Tang and Wei, 2019b;Wei, 2019aWei, , 2019bWei et al, 2019c) and many other uncertain and fuzzy environments (Lu et al, 2019a;Wei et al, 2019cWei et al, , 2019d.…”

VIKOR Method for MAGDM Based on Q-Rung Interval-Valued Orthopair Fuzzy Information and Its Application to Supplier Selection of Medical Consumption Products

“…Medical supplies products have their own characteristics to distinguish it from other types of products, which can be distinguished from their production, transportation, marketing, and other aspects. It can be seen that supplier selection of medical consumption products is the classical MADM or MAGDM issue [61][62][63][64][65][66][67][68][69][70][71][72]. In this subsection, an example for supplier selection of medical consumption products with q-RIVOF information shall be presented in order to demonstrate the method proposed in this paper.…”

Pythagorean 2-tuple linguistic power aggregation operators in multiple attribute decision making

“…Finally, a practical example for enterprise resource planning (ERP) system selection is given to verify the developed approach and to demonstrate its practicality and effectiveness. In the future, the application of the proposed aggregating operators of P2TLSs needs to be explored in the decision making, risk analysis and many other fields under uncertain environment (Deng & Gao, 2019;Deng, Wang, & Wei, 2019;Gao, Lu, Wei, & Wei, 2018;Han & Liu, 2011;Li & Lu, 2019;Li, Wei, & Lu, 2018;Lin, Zhao, & Wei, 2013;Liu, 2009;Liu, Jin, Zhang, Su, & Wang, 2011;Liu, Liu, Liu, & Pang, 2017;Mardani et al 2015;Merig o, 2008Merig o, , 2009aMerig o, , 2009bMerig o, , 2010Merig o, Casanovas, & Mart ınez, 2010;Merig o & Casanovas, 2009;Ngan, 2011;Tang et al, 2019;Wang, Gao, & Lu, 2019;Wang, Wang, et al, 2019a,b;Wei, 2018Wei, , 2019aWei, , 2019bWei, , 2019cWei, Wang, Wei, Wei, & Zhang, 2019a, 2019bWei & Wei, 2018;Wu, Gao, & Wei, 2019;Ye, 2009a,b).…”
