基于AHP-独立性权数法的列车旅客界面设计评价

为了克服高速列车旅客界面现有评价模型指标单一、赋权方法主观随意性、缺乏定量分析的局限性,首先,对新型双层高速列车的试验样车展开满意度调查,在此基础上从评价指标的全面性、系统性和层次性出发,构建了由设施尺度、安全设计、功能使用、空间环境和美学设计5类评价准则和36项具体指标组成的层次指标体系;其次,提出一种AHP法(层次...

Evaluation of Train Passenger Interface Design Based on Analytic Hierarchy Process with Independent Weight Method

In order to overcome the limitations of the existing evaluation model of high-speed train passenger interface, such as single index, subjective randomness of weighting method and lack of quantitative analysis. Firstly, a satisfaction survey was conducted on the new type double deck high-speed test sample train. On this basis, starting from the comprehensiveness, systematicness and hierarchy of the evaluation indicators, a hierarchical index system is constructed, which consists of five evaluation criteria and 36 specific indexes, including facility scale, safety design, function use, space environment, and aesthetic design. Secondly, a fuzzy comprehensive evaluation model is proposed, which combines the analytic hierarchy process (AHP) method with independent weight method, it retains the subjective opinions of experts and objective information in the passenger experience survey data. Finally, the weights of each level of the passenger interface evaluation index system are solved based on expert judgment data and survey score data, and the evaluation grades of the new prototype and the existing train are calculated. The results show that the comment grade of the new prototype is satisfactory with the membership degree of 0.3977, and the comment grade of the existing train is very satisfactory with the membership degree of 0.4422. According to the weight calculation, the design improvement sequence of passenger interface should be facility scale, functional operation, space environment, safety design, and aesthetic design. In the evaluation criteria, the man-machine surface of the seat, the rounded corners of the facility, the adjustability of the seat, the air quality and the color coordination are the factors that have the greatest impact on passenger satisfaction.
