城市轨道交通列车开行方案研究

Research on Train Operation Scheme of Urban Rail Transit

通过以列车编组、最小时间间隔、列车上座率等为约束条件,建立以旅客出行成本最小和企业运营成本最小的非线性双目标整数规划模型,引入平均运距对乘客出行时间进行求解.通过对大连市快轨3号线主线开行方案的确定,来验证模型的合理性.计算结果表明,本模型得到的开行方案满足约束条件,符合旅客与企业双方的利益要求.

By using the train formation, the minimum time interval, train ridership such as constraint conditions is a non-objective integer programming model established based on travel and operations costs, and an average distance of passenger travel time is introduced. By determining the main operation scheme of Dalian Rapid Rail Line 3 to verify the rationality of the model, the results show that the operation scheme satisfy the constraint conditions of this model, which conforms the requirements of the passenger and business interests of both parties.
