摘要
市域轨道交通的快慢车运营模式在一定程度上有利于改善乘客服务水平、提高市域线路运输效率、降低企业成本,而确定快慢车模式下的开行方案是一个多方案、多目标的决策问题。从乘客和企业两个角度构建开行方案综合评价体系,设计开行方案的优度综合评价模型;运用可拓学原理建立开行方案物元集,给出各项评价指标的动态衡量条件;采用组合赋权的方法确定各项评价指标的综合权重,计算关联度描述各个方案符合各项指标要求的程度;最后依据优度计算结果给出适用于初期、近期的优选方案。
To certain extent,the express and local train mode of the municipality rail transit is conducive to improving passenger service level and the efficiency of municipality rail transit and reducing enterprises’costs,but there is a multi-objective problem for determining the operation scheme with the express and local train mode.This paper constructed a comprehensive evaluation system of the operating schemes from the perspective of passengers and enterprises,and designed a comprehensive evaluation model for the operating scheme’s priority degree.The principle of extenics was used to establish the matter element set of the operating scheme,and the dynamic measurement conditions of each evaluation index were given;What’s more,the combined weight method was used to determine the comprehensive weight of each evaluation index;then the degree of compliance of each scheme was olesoribed according to the calculated correlation degree;finally,the optimal scheme suitable for the initial,medium term was given based on the results of priority degree.
