摘要
根据自行车出行问题的特点和影响因素构建自行车出行的评价指标体系,并利用熵权群组特征根法来确定评价指标的权重,根据自行车出行的评价信息具有模糊性和灰色双重性的特点,利用灰色模糊综合评价法建立自行车出行的二级模糊综合评价模型。最后通过对济南市自行车出行进行评价,证明此方法的正确性和有效性。
In order to analyze the bicycle traffic in a city, an evaluation index system is constructed according to the features and influencing factors of bicycle riding problems. The entropy weight group characteristic root method is used to determine the weights of evaluation indexes. Because the evaluation of bicycle riding information has the features of fuzziness and gray dualism, a grey-fuzzy comprehensive evaluation method is used to establish two-level fuzzy comprehensive evaluation model of bicycle riding. Finally, a case in the Ji^nan bicycle traffic proves the correctness and effectiveness of this method.
