基于模糊综合评价的动态踝足矫形器设计评价研究
|
摘要
为客观评价产品设计方案的用户满意度和合理性,提出一种将产品模糊定性指标转换为定量指标并决策出最佳设计方案的评价模型。针对动态踝足矫形器(Dynamic Ankle-Foot Orthosis,DAFO)的设计特点和应用需求,通过Delphi法获得其安全性、舒适性、美观性3个方面的1级影响指标,借助层次分析法(Analysic Hierarchy Process,AHP)和亲和图(KJ)法进行影响指标的层次划分和分类,从而建立DAFO的定性多层次评价体系。通过AHP理论,结合Yaahp软件得出各评价指标权重的同时,使用狄克逊(Dixon)准则消除评价粗大误差,再根据模糊综合评价法(Fuzzy Comprehensive Evaluation,FCE)对3种设计方案建立评价集和关系矩阵,并结合加权平均算子计算隶属度区间,对设计方案进行综合评价,从而实现对DAFO的定量优劣排序。评价结果表明:该方法可有效为产品设计方案提供决策依据,同时以数量化的方式为其提供客观评价依据。
In order to objectively evaluate user satisfaction and rationality of product design schemes, an evaluation model was proposed to convert product fuzzy qualitative indicators into quantitative indicators to determine the best design scheme. Aiming at the design features and application requirements of dynamic ankle-foot orthosis(DAFO), the first-level impact indicators of safety, comfort and aesthetics were obtained through Delphi method. The hierarchical division and classification of impact indicators were carried out through AHP and KJ method to establish a qualitative and multi-level evaluation system of DAFO. Based on AHP theory and Yaahp software, the weight of each evaluation index was obtained. Meanwhile,the gross error of evaluation was eliminated by Dixon criterion. Then, fuzzy comprehensive evaluation was performed to establish evaluation set and relationship matrix on three design schemes. The membership interval was calculated by weighted average operator. The comprehensive evaluation was performed on the design scheme to realize DAFO quantitative priority. The evaluation results showed that this method can effectively provide selection basis for the product. At the same time, an objective evaluation basis was provided in a quantitative way.
