Combining Grey Relationship Analysis and Neural Network to Develop Attractive Automobile Booth Design

Abstract EN

Miryoku engineering is a design concept based on customer preferences, with the goal of creating attractive products or spaces.

However, traditional Miryoku engineering faces two main issues: (1) the upper Kansei factor ranks the weights by the number of mentions, but it does not represent the importance of customers; (2) the mapping connection between the upper Kansei factor and the lower specific conditions adopts a statistical analysis method, which easily leads to the omission of key information.

With the development of computer-based artificial intelligence, it repeatedly simulates human thinking with simple calculation rules, which has the advantages of fewer errors and faster speed.

Therefore, on the three-level evaluation grid diagram platform established by Miryoku engineering, this paper first uses grey relationship analysis to comprehensively evaluate the priority order of Kansei words.

Secondly, for the key Kansei factors, a morphological deconstruction table that connects the original reasons and specific conditions is established.

Orthogonal design is used to screen representative combinations of design elements and create sample models by using the 3D software.

Finally, the neural network was used to establish a mapping function between the key Kansei factors and the representative product design elements, and based on this, the most perceptually attractive product design was discovered.

As a case study, the automobile booth was used to validate the effectiveness of the proposed method and significantly improve exhibitor design decisions and attendees’ satisfaction.
