The fuzzy set has its own limitations due to the membership function only. does not describe negative aspects of an object. Fermatean covers complex is most effective tool for handling ambiguous and uncertain information. aim this research work develop new techniques decision-making based on numbers. First, we construct different aggregation operators numbers, using Einstein t-norms. We define ...

Bipolar fuzzy set theory has been successfully applied in some areas, but there are situations real life which can’t be represented by bipolar sets. However, all the existing approaches unsuitable to describe positive and negative membership degree an element uncertain linguistic label have interval value, can reflect decision maker’s confidence level when they making evaluation. In order overc...

Environmental, social and governance(ESG) investing is being a popular strategy in global financial markets, which includes more comprehensive concerns over the environmental, governance aspects of investment targets. However, how to evaluate ESG performance faces multiple challenges because incomplete information, subjective judgments attribute decision-making problems. To address those issues...

Spherical fuzzy set (SFS) is also one of the fundamental concepts for address more uncertainties in decision problems than existing structures sets, and thus its implementation was substantial. The well-known sine trigonometric function maintains periodicity symmetry origin nature satisfies expectations experts over multi parameters. Taking this feature significance SFSs into consideration, mai...

Abstract The 2-dimensional uncertain linguistic variable (2DULV) can depict decision-makers’ subjective assessments on the reliability of given evaluation results, which is a valid and practical tool to express decision information. In this study, we develop an improved MABAC method with 2DULVs handle multiattribute group decision-making (MAGDM) problems where weight information attributes unkn...

Building green airports can be regarded as among the most promising routes to sustainable development of ecosystems and human health. This study aims at addressing problem airport plan selection under an uncertain context by developing multiattribute group decision making (MAGDM) model. In proposed model, assessment information is characterized in form a proportional hesitant 2-tuple linguistic...
