基于改进AHP-Fuzzy的二手车性能综合评估研究

摘要

研究二手车的性能综合评估问题，确定较为全面合理的评估指标体系。针对传统AHP的不足，提出采用三标度法及最优传递矩阵来构造判断矩阵，直接求出评价指标的权重，避免对判断矩阵的一致性检验和调整。建立基于改进AHP-Fuzzy的二手车性能综合评估模型，将仪器检测和专家打分两种方法相结合来实现定量和定性指标的模糊综合评价。在一定程度上解决二手车性能评估的模糊性问题，计算过程科学简便，为二手车的价格评估提供科学的参考依据。%Research on the comprehensive performance evaluation of second-hand car to establish a more comprehensive and rational evaluation system. This paper proposes a three demarcation method and optimal transfer matrix to construct the judgment matrix, directly obtain the weight of evaluation index, avoiding the consistency check and adjustment to judgment matrix. Establish the comprehensive performance evaluation model based on the improved AHP-Fuzzy second-hand car and realize the comprehensive fuzzy evaluation according to quantitative and qualitative index through the combination of detection equipment and expert scoring methods. In this way, the fuzziness problem of second hand car performance evaluation will be solved to certain extent. The calculating process will be simple and scientific and provide scientific reference for the price evaluation of second-hand cars.
