Abstract

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

基于区间值球面模糊层次分析法的木制玩具关键属性分析

木制玩具的评估是一个复杂的过程，在许多相互冲突的标准存在的情况下，决策者可能会不知所措。因此，本研究提出了一个模糊决策模型来识别和优先考虑木制玩具的关键属性。为此，采用模糊多准则决策方法之一的区间值球面模糊层次分析法(AHP)来获取权重向量。首先，将木制玩具评价问题表述为多准则决策问题。在专家的帮助下，确定了5个主要标准和20个次要标准。决策团队对标准进行两两比较。最后，计算出各指标的优先级权重，并给出各指标的排序顺序。此外，通过对区间型-2模糊层次分析法、区间值毕达哥拉斯模糊层次分析法和球面模糊层次分析法的比较分析，支持了所得结果的有效性。根据建模结果，最重要的标准是“没有小零件和锋利的边缘”，“不含有害的木材防腐剂和油漆”，“工艺质量”，“有助于精神运动发展”和“有助于认知发展”。所提出的框架可以适用于玩具评估或改进的类似决策过程。因此，这项研究的结果将有助于制造商、设计师和消费者做出有意识的决定。
