摘　　要：结合轨道交通建设特点,基于物元可拓数学方法、熵权理论和关联度函数,建立轨道交通建设时序决策的熵权物元可拓模型。该方法首先结合熵权理论,根据指标差异度对评价指标进行客观赋权;其次通过客观标准对评价指标的经典域进行区间界定,利用综合关联度将多指标的评价模型转化为单目标决策;然后依据定量测算的加权综合关联度值综合判定建设时序,最后以成都市轨道交通线网进行实例分析。结果表明:该决策算法所确定的结果与实际建设时序一致,且该算法可以极大拓展研究范围,表征更多分异信息,有效支撑城市轨道交通线网建设时序的综合决策。According to the characteristics of rail transit engineering, this paper establishes a model for decision-making in rail transit construction sequence based on matter-element mathematics, information entropy and independent function theory. First it conducts a quantitative analysis of the evaluation index system aiming at calculating the parameters objectively. Then the multi-ingredient of assessment is transformed into the single-object decision through the synthetic independent degree. Finally, example analysis of Chengdu urban rail transit network is conducted. The results show that the scheme determined by the decision-making method is identical to the actual construction sequence and applicable to comprehensive decision-making of rail transit construction sequence.
