Abstract

The recently developed three-dimensional spherical fuzzy sets are an extension of the ordinary fuzzy sets, which are effective in handling uncertainty and quantifying expert judgments. The similarity measure is one of the beneficial tools to define the degree of similarity between two objects. It has many vital implementations such as medical diagnosis, and pattern recognition. Some different distance and similarity measures of SFSs have been proposed to literature, but they are limited when compared to other extensions of fuzzy sets. In this study, some novel distances and similarity measures of spherical fuzzy sets are presented. Then, we propose the novel distance measurements such as spherical fuzzy Minkowski k-Chord distance, weighted spherical fuzzy Minkowski k-Chord distance. In addition, f-similarity measures are developed under a spherical fuzzy environment. The newly defined similarity measures are applied to pattern recognition for the COVID-19 virus. In this application, the goal is to determine the main significant group of parameters that cause to spreading of COVID-19 virus in different countries separately. A comparative analysis of new similarity measures is established and some advantages of the proposed study are discussed. [ABSTRACT FROM AUTHOR]

Abstract

Today, occupational health and safety is a prominent issue in all branches of the industry. In Turkey, shipyards are highly prone to accidents related to occupational safety. Clearly defining hazard risks and taking precautions against identified priority risks are essential in preventing these risks. This study proposes a two-stage risk-assessment method based on spherical fuzzy sets (SFSs), which is a new fuzzy set theory. A systematic risk-assessment tool with the SFSs was developed combining two of the most reliable decision-making methods: "Analytical hierarchy process (AHP)" and "VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR)." The proposed method was applied in a real case study considering the shipyards in Turkey. Results showed that the developed two-stage risk-assessment approach provides reasonable results in identifying high-risk hazards to ensure occupational safety in a shipyard. A sensitivity analysis was conducted to show the reliability and validity of the results. [ABSTRACT FROM AUTHOR]
