目的 探究消费者对共享单车的需求偏好，获取用户和设计师对产品的认知差距，并提出相应的设计决策，为共享单车以及两轮车行业的产品创新提供启迪与参考。方法 从设计师思维与消费者偏好的视角出发，对共享单车消费者偏好的各项设计原则(属性)进行细致分类，建立8个评价维度与41个评价特征，采用KANO模型对有效回收样本进行定量统计及定性分析。结果 基于前期调研与KANO模型分析，提出后共享时代单车设计的相关策略。结论 在后共享单车时代下，设计师需要根据用户真实的产品偏好与体验感知进行设计策略的研究，以设计出真正满足用户需求和体验期望的产品。同时也证明KANO模型作为一种阐明用户不同感性需求的方法，有助于设计师进行设计决策的综合判断，提升设计的竞争力。     

A method of constructing an inspiration library driven by user-perceived preference evaluation data for biologically inspired design

Biologically inspired design (BID) is one of the common methods for product design. To solve the problem of inaccurate acquisition of inspirational creatures due to the lack of user perception preference analysis, a data-driven intelligent service model for BID considering user perception needs is proposed based on Kansei engineering. Firstly, by extracting the perceptual features of creatures from the semantic source elements of products through mapping and encodes them, we proposed a data acquisition method based on intuitionistic fuzzy sets considering different customer preference distributions, bridging the gap caused by the asymmetry between designers and users. Secondly, the functional relationship between biometric features and user-perceived attributes is identified and predicted, and a predictive model of biodata considering user preferences is obtained by multiple linear regression analysis. Finally, based on the data clustering and reorganization theory to understand the organization and dynamics of the database, the construction of a BID library was completed, and the design resources in the library were used as analyzed knowledge for designers to plan design activities. Taking the bionic design of a UAV product as an example, a prototype of a computer-aided design service system was developed based on the theory proposed in the article, and the analyzed knowledge was used to improve the efficiency and science of the design, effectively verifying the usefulness of this study for design. To a certain extent, this study addresses the problem of cognitive limitations of designers and cognitive differences between designers and users, promotes the application of bioinspiration in product design, and improves the marketability of design solutions.     

基于推理注意力机制的二阶段网络图像修复

现有的图像修复方法在处理大面积缺失或高度纹理化的图像时，通常会产生扭曲的结构或与周围区域不一致的模糊纹理，无法重建合理的图像结构。为此，提出了一种基于推理注意力机制的二阶段网络图像修复方法。首先通过边缘生成网络生成合理的幻觉边缘信息，然后在图像补全网络完成图像的重建工作。为了进一步生成视觉效果更逼真的图像，提高图像修复的精确度，在图像补全网络采用推理注意力机制，有效控制了生成特征的不一致性，从而生成更有效的信息。所提方法在多个数据集上进行了实验验证，结果表明该图像修复方法的结构相似性指数达到了88.9%，峰值信噪比达到了25.56 dB，与现有的图像修复方法相比，该方法具有更高的图像修复精确度，生成的图像更逼真。     

基于魅力工学的盲盒玩偶外观要素研究

目的 随着潮玩市场的不断发展，盲盒玩偶受到了大量年轻消费者的青睐。通过研究盲盒玩偶外观与消费者偏好之间的关系，可以了解现代年轻群体的审美偏好，从而辅助设计师创造出更多满足消费者偏好的产品。方法 基于魅力工学等研究方法展开定性与定量研究。以POP MART盲盒玩偶为研究对象，首先进行深度访谈，根据访谈内容绘制盲盒玩偶外观评价构造图，得到消费者对偏好的盲盒玩偶外观的原始评价、抽象感受和关注的具体要素;再结合抽象语义设计Likert问卷，并进行问卷调研，以此获得盲盒玩偶的魅力评价均值;最后运用数量化I类理论进行多元回归分析，建立多个要素与消费者审美偏好之间的线性关系。结果 利用SPSS26.0统计软件进行定量研究，得到“治愈温馨”“纯洁可爱”“潮酷个性”“有趣搞怪”四类语义分别与消费者吸引力的线性关系，以及具有显著影响的外观设计要素。结论 研究获得了消费者对不同语义盲盒玩偶外观的审美偏好与关注要素，以及不同职业、不同年龄段消费者对盲盒玩偶外观审美偏好程度的差异。研究结果对潮玩设计师的创作具有参考性意义，也可将研究结果拓展应用于小型艺术装饰品/创意玩具等类似产品中。     

犹豫模糊环境下准则具有偏好关系的TODIM方法

针对智慧制造评估时专家的决策信息具有犹豫模糊不确定性问题，提出了一种关于准则具有犹豫模糊偏好关系的改进交互式多准则决策（TODIM）方法。首先提出了准则间的犹豫模糊偏好关系概念，并证明了其基本性质。在TODIM方法优势度的计算过程中，将准则权重犹豫模糊偏好关系替代原有的精确值权重，使信息的准确性最大化。将该方法用于智能制造的评估上，实例分析结果表明所提方法是可行和有效的。     

婚纱消费者购买偏好及影响因素分析——以北京地区女性为例

在婚纱市场的不断发展和完善中,消费者在其中起到了重要作用。文章研究了婚纱消费者购买偏好对婚纱业的推动作用,并以北京地区婚纱消费者为研究对象,提出婚纱产品描述、炫耀性消费心理、购买经验、婚纱产品知识四个关键影响因素,并通过阅读相关文献提出相关假设。运用问卷调查采集数据,构建了结构方程模型。研究表明,四要素与感知价值之间存在正相关,并与感知风险存在负相关;感知价值与消费者购买偏好之间存在正相关;感知风险与消费者购买偏好之间存在负相关;感知风险与感知价值存在中介作用。根据研究结果,文章提出相应对策。     

Integrated rough VIKOR for customer-involved design concept evaluation combining with customers’ preferences and designers’ perceptions

Customer-involved design concept evaluation (DCE) allows customers to take part in evaluating the design alternatives to get more popular design concept. Traditional customer-involved DCE methods still focus on the collection of customer responses and only consider cost and benefit characteristics of design criteria in multi-criteria decision-making (MCDM) based evaluation process. Few studies have customized the decision-making algorithms specifically aimed at customers’ preferences. This paper further explores the customers’ influences in the early stages of the product design development, and proposes a new rough number based MCDM model (i.e., VIKOR) incorporating customers’ preferences for design specifications along with designers’ perceptions for the characteristics of design criteria (cost and benefit) to perform concept evaluation under subjective environment, and this proposed method is named as integrated rough VIKOR (IR-VIKOR). The objective of this study is to identify the best design concept which maximizes the satisfactions of expectations from most customers as well as conforms to the characteristics of design criteria. Firstly, Shannon entropy is used to obtain the weightings and relative importance ratings of design criteria from the customers’ preferences. Secondly, the customers’ preferences for design attribute values, the importance ratings of design criteria and the characteristics of design criteria are combined together to define the ideal solutions to calculate the rough evaluation index of each design alternative in IR-VIKOR, and finally the ranking result is provided by IR-VIKOR to determine the best design concept. A practical design example is introduced to illustrate the evaluation process of this proposed method, and the empirical comparisons are further carried out to validate its superiority for DCE. Through the sensitivity analysis experiments including i) inside IR-VIKOR, and ii) between IR-VIKOR and other classical MCDM methods, the proposed method is proved to be a reliable and feasible customer-involved DCE approach.
