“…While people evaluate the criteria and alternatives in the decision process, they can use fuzzy numbers better to reflect uncertainty (Ayyildiz et al, 2020). In this study, we apply Pythagorean fuzzy sets to deal with vagueness better.…”

“…The method can be used as an alternative method that can be applied to rank the factors. However, numerical (crisp) values may be insufficient when evaluating many real‐life situations because human thoughts and judgments especially preferences often contain uncertainty and fuzziness (Ayyildiz & Taskin Gumus, 2020). For this reason, the TOPSIS method is applied under the Pythagorean fuzzy environment to avoid these negativities.…”

Many governments decided to cancel face‐to‐face teaching and learning activities in schools and universities. They replaced them with online teaching and distance learning activities to prevent the spread of Coronavirus disease 2019 (COVID‐19). Due to this sudden change, students experienced some anthropometric, environmental, and psychosocial difficulties at home during the distance learning process. This study focuses on determining the importance of anthropometric, environmental, and psychosocial factors in the distance learning process during the COVID‐19 pandemic. This study presents main factors and their subfactors affecting ergonomic conditions of university students during distance learning. A novel distance learning ergonomics checklist is proposed based on the Occupational Safety and Health Administration checklists. The data are collected via a questionnaire filled by 100 university students who attend the Ergonomics course online. Then, the integrated methodology includes Voting Analytic Hierarchy Process integrated Pythagorean Fuzzy Technique for Order Preference by Similarity to An Ideal Solution method is adopted to prioritize the factors determined. Thirty‐nine different subfactors are evaluated under five titles, and the most important factors are determined using the proposed methodology. With the results achieved, it is seen that the suggested checklist and proposed methodology can be used by public and private education organizations as a guide for improving their distance learning strategies.

Supply chain operations reference (SCOR) is a combined benchmarking, business process reengineering, and best practices, and it also references a model that is intended to be an industry standard. SCOR model is one of the best models to describe supply chain activities in operations management for research and practice alike. There are radical changes in the structure of supply chains as well as developing technology in today’s information age. The purpose of this paper is to extend the SCOR model with new metrics related to Industry 4.0 and digitalization to understand and evaluate the performance of supply chains. New metrics added to the SCOR model and a novel SCOR 4.0 model is proposed. The novel performance evaluation model is structured as a three-level hierarchical structure to evaluate the supply chain. This problem is handled as a multi-criteria decision-making problem. This study uses the hybrid Best worst method and Pythagorean fuzzy AHP method to determine the weights of metrics. SCOR model is adapted to performance evaluation of the supply chain in the globalizing world. The most important metrics on the supply chain performances are determined and classified. Level 1 metrics are evaluated by Best worst method and their inner levels are evaluated by the Pythagorean fuzzy AHP method and the importance weights of each level 2 and level 3 metrics are obtained. A real application for the oil supply chain is presented to show the applicability of the proposed model. It is aimed to show the SCOR 4.0 model can be used by both public and private sectors to improve their supply chain strategies in globalizing world.

“…With the rise of fuzzy sets, all kinds of extended fuzzy information begin to appear, such as interval fuzzy number, triangular fuzzy number, and trapezoidal fuzzy number (TrFN). Among them, TrFN is the most generalized and accurate form, which can be reduced to other fuzzy information forms by adjusting membership function, so it has been paid great attention [7,8]. In addition, in terms of qualitative evaluation, the linguistic variables (LVs) introduced by Zadeh [9] promote the convenient expression of qualitative information, which is more in line with human evaluation habits.…”

“…Among these methods, the VIKOR method has an obvious advantage, i.e., it can use the group utility value and individual maximum regret value to find a compromise solution. In addition, the ELECTRE [7], PROMETHEE [34], and QUALIFLEX [35] method can measure the priority of alternatives by considering the possibility degree, preference index, and concordance index between alternatives, respectively, and then get the ranking results. Although these traditional methods have many steps, the evaluation results obtained by them are more accurate and more stable than those obtained by those methods based on aggregation operators.…”

Considering the advantages of trapezoid fuzzy two-dimensional linguistic variables (TrF2DLVs), which can not only accurately describe the qualitative evaluation but also use qualitative linguistic variables (LVs) to describe the confidence level of this evaluation in the second dimension, this paper proposes a novel method based on trapezoidal fuzzy two-dimensional linguistic information to solve multiple attribute decision-making (MADM) problems with unknown attribute weight. First, a combination weight model is constructed, which covers a subjective weight determination model based on the proposed trapezoidal fuzzy two-dimensional linguistic best-worst method (TrF2DL-BWM) and an objective weight determination model based on the proposed CRITIC method. Then, in order to accurately rank the alternatives, an extended VIKOR-QUALIFLEX method is proposed, which can measure the concordance index of each ranking combination by means of group utility and individual maximum regret value of each evaluation alternative. Finally, a practical problem of lean management assessment for industrial residential projects is solved by the proposed method, and the effectiveness and advantages of the method are demonstrated by comparative analysis and discussion.
