基于 FDM 与 FAHP 的儿童滑板车设计评价与改进

儿童滑板车设计评价的影响因素复杂多样，难以通过量化的方法衡量这些因素对于产品设计的 重要性。采用模糊德尔菲法(FDM)定量地筛选产品设计评价指标要素，建立儿童滑板车设计层级指标模型。 然后，运用模糊层次分析法(FAHP)计算出各项指标要素权重，综合评价设计方案，得出儿童滑板车总体评价 分值，最终提出优化与改良意见。FDM 与 FAHP 结合可以较为系统地对产品进行量化设计与评价，减少设 计过程中的主观因素，使设计更加科学、理性与严谨，也为儿童产品设计方案的选择和优化提供了可量化的 参考依据。

Design evaluation and improvement of Children’s scooter based on FDM and FAHP

The influencing factors of the design evaluation of children’s scooter are complex and diverse, and it is difficult to measure the importance of these factors to product design through quantitative methods. Fuzzy Delphi method (FDM) was employed to quantitatively screen product design evaluation index elements, and a hierarchical index model for design of children’s scooter was established. Then, the fuzzy analytic hierarchy process (FAHP) was adopted to calculate the weight of each indicator element, the design plan was comprehensively evaluated, and the overall evaluation score of children’s scooter was obtained. Finally, the suggestions for optimization and improvement were proposed. The combination of FDM and FAHP can systematically design and evaluate products quantitatively, reduce non-objective factors in the design process, make the design more scientific, rational and rigorous, which also provides a quantifiable reference basis for the selection and optimization of children’s product design schemes.
