【摘要】：用户的感性诉求日益获得产品设计师和企业决策者的关注,为了使产品开发人员在开发新产品时能满足用户多维复合的感性诉求,提出一种结合熵处理、灰色关联分析和逼近理想解排序(technique for order preference by similarity to an ideal solution,TOPSIS)的方法,用于产品设计方案的评估。首先,在运用K-mean聚类分析和因子分析方法分别获得符合用户感性认知的典型样本和典型感性意象的基础上,运用语意差异法获得用户-意象初始评价值;其次,应用信息熵计算评估指标的权重;最后,采用灰色关联分析与TOPSIS相结合的方法实现用户多维意象特定要求下对备选设计方案的排序优选。以3D打印机设计方案优选为例,验证了方法的可行性。研究结果表明,该方法符合用户实际的复杂认知,能有效客观地对产品设计方案进行评估和优选,具有实际应用价值和指导作用。
[Abstract]:The user's perceptual appeal is gaining more and more attention from product designers and enterprise decision-makers. In order to make product developers meet the multidimensional complex perceptual demands of users when developing new products, a combination of entropy processing, grey relational analysis and approximation of ideal solutions (technique for order preference by similarity to an ideal solu) is proposed. The method of tion, TOPSIS) is used to evaluate the design scheme of the product. First, on the basis of using K-mean clustering analysis and factor analysis to obtain the typical samples and typical perceptual images which conform to the user's perceptual cognition, the initial evaluation value of the user image is obtained by the semantic difference method. Secondly, the right of information entropy is used to calculate the right to evaluate the index. At last, the method of grey association analysis and TOPSIS is used to realize the sorting and optimization of the alternative design scheme under the specific requirements of the user's multidimensional image. The feasibility of the method is verified by the optimization of the 3D printer design scheme. The results show that the method conforms to the actual complex cognition of the user and can effectively and objectively set up the product. The scheme is evaluated and optimized, which has practical application value and guidance function.
