为了优化公交化城际列车的运营时刻表,获得最大社会效益,将时刻表的优化问题分解为确定列车首发时间、列车发车间隔时间以及列车每日开行趟次3个相互关联的子问题,并以旅客出行费用和铁路企业运营成本费用的加权和最小化为目标函数,建立公交化城际列车时刻表优化模型。优化结果表明,在总费用最小时,线路的最优开行趟次为30,可得到公交化城际列车的运营时刻表,所得到的结果与通过实际分析得到的最优结果完全一致,且比单纯考虑旅客费用或企业运营费用时的结果更合理,使得城际列车时刻表的制定更加科学化,并符合社会效益最大化的要求。
In order to optimize the operation schedule of bus intercity train and obtain the greatest social benefit, the optimization problem of timetable is decomposed into three interrelated subproblems of departure time, train departure time and train daily opening time. Based on the objective function of minimizing the weighted sum of travel cost and operating cost of railway enterprises, an optimization model of bus transit intercity train schedule is established. The result of optimization shows that when the total cost is the minimum, the optimal route opening time of the route is 30, and the operation schedule of the bus intercity train can be obtained. The results obtained are exactly the same as those obtained by the actual analysis, and the ratio Considering the passenger expenses or the operating expenses of enterprises, the result is more reasonable, making the formulation of intercity train schedules more scientific and in line with the requirements of maximizing social benefits.
