This study applied Kansei Engineering’s point of view to design multifunction escape lamp, through screening optimized design the best combination of design can be obtained, this promotes quality and efficiency of product design. For screening correlation design factors, this paper used 5W1H method to analyze and vote design factors. Next, using Interpretive Structural Modeling (ISM), a variety of design structure roadmap were analyzed, taking advantage of the experts’ opinion to apply Local Grey Relational Analysis-Analytic Hierarchy Process (LGRA-AHP) method that obtained the consensus assessment of the best structural design strategy. The research result showed that not only collected the best arrangement of design paths, but also parsed the main design conditions of multifunction escape lamp and promote the integrity
of product.
