“…Step 1.2: According to the relationships between the linguistic terms and interval-valued Pythagorean fuzzy numbers [74], we can construct the transformation between the linguistic terms and the corresponding q-ROFNs (q = 3) as shown in Table 1. Then, decision makers use the linguistic terms to assess the green suppliers as shown in Table 2; thus, the q-ROF evaluation matrix F k = a k ij 4×6 is obtained.…”

With environmental issues becoming increasingly important worldwide, plenty of enterprises have applied the green supply chain management (GSCM) mode to achieve economic benefits while ensuring environmental sustainable development. As an important part of GSCM, green supplier selection has been researched in many literatures, which is regarded as a multiple criteria group decision making (MCGDM) problem. However, these existing approaches present several shortcomings, including determining the weights of decision makers subjectively, ignoring the consensus level of decision makers, and that the complexity and uncertainty of evaluation information cannot be adequately expressed. To overcome these drawbacks, a new method for green supplier selection based on the q-rung orthopair fuzzy set is proposed, in which the evaluation information of decision makers is represented by the q-rung orthopair fuzzy numbers. Combined with an iteration-based consensus model and the q-rung orthopair fuzzy power weighted average (q-ROFPWA) operator, an evaluation matrix that is accepted by decision makers or an enterprise is obtained. Then, a comprehensive weighting method can be developed to compute the weights of criteria, which is composed of the subjective weighting method and a deviation maximization model. Finally, the TODIM (TOmada de Decisao Interativa e Multicritevio) method, based on the prospect theory, can be extended into the q-rung orthopair fuzzy environment to obtain the ranking result. A numerical example of green supplier selection in an electric automobile company was implemented to illustrate the practicability and advantages of the proposed approach.

Occupational health and safety (OHS) history dates back to ancient human history due to a decrease the occupational accidents and diseases. Human is obliged to do work in order to sustain life. The works in general consist of the works done with body strength. OHS is a basis to reduce occupational accidents in an acceptable level, and it covers employee health, safety, and welfare in the workplace. There are certain or uncertain risks in terms of workplace structure and location. OHS investigates the actions to be taken to minimize these risks on the basis of workplace safety. Workers exposed to occupational hazards have a higher risk of developing work-related illnesses and injuries. Risk assessment is one of the most important structures in terms of identifying and evaluating the risks to which the employee and employer are exposed. Comparisons of risk assessment methods, which are divided into two categories as quantitative and qualitative, in the scope of occupational health and safety and the detailed analysis of the study, the differences between the methodologies have been revealed and accordingly, the and the necessary applications have been put forward. Occupational safety risk assessment is mandatory for the implementation of risk control in the workplace, professional activities and protection of worker health. The employer can carry out this work in-house or by taking external services. The aim of this study is to compare the risk assessment methods used in the analysis of hazards and risks that may arise in terms of occupational health and safety and to evaluate their effectiveness in determining the measures to be taken as a result.

“…These sets are the generalization to the intuitionistic fuzzy sets in some condition where intuitionistic fuzzy sets cannot address the uncertainty. Therefore, Pythagorean fuzzy sets are more powerful and flexible to solve problems involving uncertainty [28,[31][32][33][34].…”

Risk analysis (RA) contains several methodologies that object to ensure the protection and safety of occupational stakeholders. Multi attribute decision-making (MADM) is one of the most important RA methodologies that is applied to several areas from manufacturing to information technology. With the widespread use of computer networks and the Internet, information security has become very important. Information security is vital as institutions are mostly dependent on information, technology, and systems. This requires a comprehensive and effective implementation of information security RA. Analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) are commonly used MADM methods and recently used for RA. In this study, a new RA methodology is proposed based on AHP-TOPSIS integration extended with Pythagorean fuzzy sets. AHP strengthened by interval-valued Pythagorean fuzzy numbers is used to weigh risk parameters with expert judgment. Then, TOPSIS with Pythagorean fuzzy numbers is used to prioritize previously identified risks. A comparison of the proposed approach with three approaches (classical RA method, Pythagorean fuzzy VIKOR and Pythagorean fuzzy MOORA) is also provided. To illustrate the feasibility and practicality of the proposed approach, a case study for information security RA in corrugated cardboard sector is executed.
