摘要
在综合评价时,权重的确定直接影响到评价结果的准确性和科学性。为此,基于粗糙集的模糊熵提出了一种新的综合评价赋权数的方法,有效表达了不同的指标面对不同的评价方案有不同的信息容量,故每个指标对不同的评价方案应赋予不同的权重,使得权系数既易于解释,又更加客观准确。进而对华北、东北、华东三大地区的城市基础设施水平进行TOPSIS方法分析,得出了三大地区的城市基础设施水平的排名,通过数据分析得出三个地区在不同评价指标下存在的优点和缺点,可以为城建部门提供一定的参考意见,查漏补缺。
In the comprehensive evaluation,the allocation of weights affects directly the accuracy and scientificity of evaluation results.Based on fuzzy entropy of the rough sets,a new method of determining weight in comprehensive evaluation is put forward in this paper,expressed effectively the different indicators to the different appraisal schemes have different information capacity,therefore each indicator to the different appraisal schemes should be given different weights,making the weight coefficient is easy to explain,and more objective and accurate.City facility level of North China,Northeast,and East China is analyzed by TOPSIS method,obtaining comprehensive place for city facility level of the three regions,the advantages and disadvantages of the three regions for city facility construction are discovered,and providing some suggestions for city facility construction of the three regions.
