基于主客观赋权法的汽车静态感知质量评分研究

汽车静态感知质量评价具有评价层次多、评价指标多、评价人员多等特点,针对整车静态感知质量评分计算较难问题,提出一种评分计算方法。该方法运用层次分析法确定各评价指标和评价人员的主观权重,并利用熵值法对各评价指标的主观权重进行修正,利用评价人员个人评分和集体评分的偏离程度与熵值法优化评价人员权重,进而调整更新集体评分结果,经过多次优化,直至集体评分趋于稳定。最后通过1个算例,说明了计算的过程,证明了方法的可行性。

The Research on Vehicle Perceived Quality Score Based on the Subjective and Objective Weighting

Vehicle static perception quality evaluation has the characteristics of multiple evaluation levels, multiple evaluation indicators and multiple evaluators. Aiming at the difficulty of calculating vehicle static perception quality score,a scoring calculation method is proposed. This method uses the analytic hierarchy process to determine the subjective weights of each evaluation index and evaluation personnel, uses the entropy method to revise the subjective weights of each index, uses the deviation degree of the individual and collective evaluation scores of the evaluators and the entropy method to optimize the weight of the evaluators, and then adjusts and updates the collective evaluation results, after many times of optimization. Until the collective score tends to be stable. Finally, an example is given to illustrate the calculation process in detail and prove the feasibility of the method.
