Satisfaction Evaluation of the Passenger Interface Design of High-Speed Train Based on G1-Entropy Weight Method

摘要

High-speed train passenger interface (PI) is of great significance for passengers' experience. CRH3X is a new type of double-layer high-speed train at a closed testing stage, with independent research and development of China. In order to feed back problems existing in the current PI design of CRH3X, the G1 method was introduced and combined with the entropy weight method for quantification of differences of importance degrees between different indexes based on empirical data of passengers' satisfaction. The innovation is advantageous in that through combination of experts' experience and passengers' actual experience information, randomness in subjective empowerment is avoided. In addition, with reference to those evaluation results, designers can better determine an improved preference strategy.
