Analysis of Key Attributes of Wooden Toys via an Interval-Valued Spherical Fuzzy Analytic Hierarchy Process

The evaluation of wooden toys is a complicated process and can be overwhelming for decisionmakers in the presence many conflicting criteria. Hence, this study proposes fuzzy decision-making model to identify prioritize key attributes toys. For purpose, interval-valued spherical analytic hierarchy (AHP), which one multicriteria methods, applied obtain weight vectors. Firstly, toy problem formulated as problem. Then five main criteria twenty subcriteria are defined with help experts. team carries out pairwise comparisons As result, priority weights computed ranking order revealed. Additionally, validity obtained results supported by conducting comparative analysis between other popular methods: interval type-2 AHP, Pythagorean AHP. According modeling results, most important “absence small parts sharp edges”, “free harmful wood preservatives paints”, “workmanship quality”, “contribution psychomotor development”, cognitive development”. proposed framework adapted similar decision processes or improvement Consequently, findings research will manufacturers, designers, consumers making conscious decisions.
