基于用户行驶需求的轻客整车性能评价
|
摘要
为评价某型轻客的整车性能,建立了整车性能评价体系,并调研了用户的行驶需求,用户根据行驶需求的满足程度对各性能进行打分评定。分别运用层次分析法、灰色关联度法和结构熵权法确定各性能的权重系数,将其与用户评分相结合,得出整车性能评价结果。结果表明三种方法得出该车型的质量等级均一致,但相对于其它两种方法,结构熵权法能最大程度考虑用户行驶需求。因此,根据结构熵权法的结果,对该型轻客性能提出相应的改进意见。
In order to evaluate the vehicle performance of a certain type of light bus,this paper establishes the vehicle performance evaluation system and investigates the user driving needs,user scores the performance according to the satisfaction of driving needs. Analytical hierarchy process,grey relational degree method,structure entropy weight method are proposed for determining the weights of the performance. Combining the weights with the user score,the result of vehicle performance evaluation is obtained. The evaluating results of the three methods are consistent. Compared with the other two methods,the structure entropy weight method pays most attention to the situation of the user driving needs. Thus,according to the result of the structure entropy weight method,the recommendations for improvement of light bus performance are proposed.
