摘要
为解决低碳交通发展水平评价中主客观权重差异和群决策定性指标量化的不确定性问题,建立基于博弈论和TOPSIS(逼近理想解排序方法)的城市低碳交通发展水平评价模型.首先,采用可拓层次分析法(EAHP)和熵权法确定指标主客观权重.其次,使用博弈论确定指标综合权重,以解决主客观权重带来的差异问题.最后,采用三角模糊数对定性指标进行量化,并结合TOPSIS进行综合评价,客观全面反映不同专家对定性指标的意见.通过上述模型对武汉市 2015-2021 年低碳交通发展各方面和综合发展水平进行评价.结果表明,2015-2021 年武汉市低碳交通发展水平呈稳步增长趋势,评价值从 0.404 8 上升到 0.606 7,与实际情况相符.该评价方法可以应用于其他城市的低碳交通发展水平评价,进而更好地推进城市低碳交通系统建设.
Abstract
To solve the problem of differences in subjective and objective weights and the uncertainty of quantifying qualitative indicators of group decisions in the evaluation of the development level of low-carbon transportation,a urban low-carbon transportation development level evaluation model based on game theory and TOPSIS is established.Firstly,the EAHP and entropy weight method are used to determine the subjective and objective weights of the indicators.Secondly,the game theory is used to calculate the comprehensive weight of indicators to solve the difference between subjective and objective weights.Finally,the Quantification of qualitative indicators is carried out using triangular fuzzy numbers,combined with TOPSIS for comprehensive evaluation,to objectively and comprehensively reflect the opinions of different experts on qualitative indicators.The above model is used to evaluate the various aspects and overall development level of low-carbon transportation in Wuhan from 2015 to 2021.The results indicate that the level of low-carbon transportation development in Wuhan has shown a steady growth trend from 2015 to 2021.The evaluation value has increased from 0.404 8 to 0.606 7,which is consistent with the actual situation.This evaluation method can be applied to the evaluation of the low-carbon transportation development level in other cities,thereby better promoting the construction of urban low-carbon transportation systems.
