中文摘要:
      针对线路纵断面化简计算结果合理性有待验证的问题,本文提出基于DP(Dynamic Programming, 动态规划)的铁路线路纵断面化简算法。该算法以优化列车区间追踪间隔为目标,考虑线路纵断面的化简的要求,结合列车区间追踪运行模型模拟列车运行情况,采用多阶段最优决策来求解线路纵断面化简问题。仿真结果表明,该算法能够很好的实现线路纵断面化简,符合《列车牵引计算规程》中线路纵断面化简相关规定,可以减少区间跟踪时间,适合实现铁路纵断面自动化简的实际应用。
英文摘要:
      Aiming at the problem that the rationality of the calculation result of railway longitudinal section simplification needs to be verified, a railway longitudinal section simplification algorithm based on DP (Dynamic Programming, Dynamic Programming) was proposed in this paper. The algorithm aimed at optimizing the train tracking interval, considered the requirements for railway longitudinal section simplification, combined the train interval tracking operation model to simulate train operation, and used multi-stage optimal decision-making to solve the problem of railway longitudinal section simplification. The simulation results show that the algorithm can achieve the railway longitudinal section simplification, and meets the relevant regulations of railway longitudinal section simplification in the " Truck Traction Calculation Regulations ", can reduce the interval tracking time, and suitable for practical applications achieve automatic railway longitudinal section simplification.
