融合可拓语义和模糊综合评价的地铁列车外观设计方法

Study on the approach to exterior design for metro trains based on extension semantics and fuzzy comprehensive evaluation

为进一步提升和彰显地铁列车外形中的地域文化特征,提出了一种基于专家和用户视角的融合可拓语义和模糊综合评价的地铁列车外观设计方法。基于可拓语义提出了文化基元概念,构建了涵盖文化载体、文化特征和文化价值的三元组,给出了地铁列车外观设计中的可拓语义分析与表征步骤;基于模糊综合评价法来评估地铁列车外观设计方案的文化特征,给出了评估流程,并以一款低速B2型成都地铁列车外观设计为例,结合专家和用户调查,从文化提取与表征、方案设计和方案评估3方面对所提方法的可行性进行了验证。研究结果表明:该方法能够有效将典型文化元素以语义符号的形式融入地铁列车的外观设计,有助于提升设计方案的地域文化特征。

To further enhance and highlight the regional cultural characteristics of metro train appearance,an approach to exterior design for metro trains based on extension semantics and fuzzy comprehensive evaluation was proposed from the perspectives of experts and users.Firstly,according to the extension semantics,the concept of cultural primitives was defined,and the triples covering cultural carriers,cultural characteristics,and cultural values were constructed.For the exterior design process of metro trains,the extension semantic analysis and representation steps were provided.Then,the fuzzy comprehensive evaluation method was adopted to evaluate the cultural characteristics of the exterior design of metro trains,and the specific evaluation process was proposed as well.Finally,taking the exterior design of a low-speed B2 type Chengdu metro train as an example,the feasibility of the proposed approach was verified from three aspects:Culture extraction and representation,scheme design and scheme evaluation based on investigations on experts and users.The results show that the method could effectively integrate typical cultural elements into the exterior design of metro trains in the form of semantic symbols,and it would be helpful to improve the regional cultural characteristics of the design scheme.
