摘　　要：在阐述青荣城际铁路概况的基础上,将青荣城际铁路沿线车站划分为3个类型等级,并且根据停站规律提出3种类型的列车运行线,构造青荣城际铁路列车运行线类型图,对青荣城际铁路进行数学建模。以最小化输送旅客的总费用为目标,以组成旅客出行径路类型边的运输能力与旅客流量相匹配为约束条件构建IPxy模型,并且提出各类型运行线上列车开行对数的计算公式,通过计算得到青荣城际铁路某高峰时段的预测客流量和开行密度,从而确定青荣城际铁路列车开行方案。Based on expounding general status of Qingdao-Rongcheng inter-city railway, the stations along the railway is divided into 3 types, and according to the stop principles, the train path of the 3 types is put forward, the type map of train path of Qingdao-Rongcheng inter-city railway is drawn and mathematical modeling of the railway is taken. Taking the total cost of minimized passenger delivery as the object and taking the traffic capacity matched with passenger flow volume which in the type edge consisted of passenger traveling route as the constraint conditions, model is established, and the calculation formula of number of train pairs for each type of path is put forward, through calculating, the forecasted passenger flow volume and operation density of Qingdao- Rongcheng inter-city railway in peak period is achieved, so as to determine the train operating scheme of the railway.
