随着高铁建设成网,既有线货运能力得到极大释放,为满足户主时效性需求的小编组高频次货物列车的开行创造了条件.当前开行方案的编制通常仅从铁路运输企业自身的经济效益出发,很少考虑货主时间价值需求对运输方案的影响;此外,在方案编制过程中,很少将发到站相同但归属于不同货主的车流区分对待.因此,本文在综合考虑铁路运输企业和货主两方面因素的基础上.结合新形势下为减少换装等待时间采取的欠轴运输策略,对既有模型的目标函数进行改造:增加单位列车的固定和变动开行费用以及不满足货主时间价值需求的惩罚费用,并进行线性化处理,降低模型求解的复杂度.设计了并行禁忌算法,实现了模型的求解,验证了模型的正确性和算法的可行性.
With the construction of high-speed rail network, the existing line cargo capacity has been greatly released, to meet the needs of the owners of Xiao Bian high-frequency time-laden goods trains opened to create the current program is usually open only from the railroad transport enterprises themselves Economic benefits, seldom consider the impact of the owner’s time value demand on the transportation scheme; in addition, in the process of program preparation, it is seldom to distinguish between the same car flow and the traffic flow belonging to different owners.Therefore, Enterprise and the owner on the basis of two factors.Combined with the new situation in order to reduce the waiting time for underwear to take under-axis transport strategy, the existing model of the objective function to be modified: to increase the unit train fixed and variable operating costs and does not meet the owner Time penalty, cost of punishment, linearization, and reducing the complexity of solving the model.A parallel taboo algorithm is designed to solve the model and verify the correctness of the model and the feasibility of the algorithm.
