摘要
利用关联规则挖掘技术,对BRT综合评价体系中各评价指标与综合评价结果之间的关系进行量化分析,得到各评价指标的支持度和可信度,并采用Apriori算法找出BRT综合评价体系中满足最小支持度和最小置信度要求的强关联规则;根据各评价指标与综合评价结果之间关联关系所具有的可信度,判断BRT综合评价体系中各评价指标设置的科学性和各指标权值分配的合理性。应用实例表明,关联规则方法对于验证BRT综合评价体系构建是否科学合理具有重要意义。
The association rules mining technology was introduced to comprehensive evaluation system of BRT to analyse the relationship between each evaluation index and the comprehensive evaluation result quantitatively.Meanwhile,the support and confidence of each evaluation index was obtained.Then the Apriori algorithm was adopted to find strong association rules which meted the minimum support and minimum confidence.According to the credibility of the relevant degree of the index and comprehensive evaluation score,the evaluation index system＇s scientific and reasonable characteristic had been analyzed.The result shows that the method is meaningful for the construction of the comprehensive evaluation system of BRT.
