基于模拟退火算法的铁路旅客列车车底套用优化研究

Railway train set assignment based on simulated annealing algorithm

为了提高铁路旅客列车车底的利用效率,利用列车晚点传播理论分析了列车晚点对旅客列车车底运用的影响,建立了铁路旅客列车车底套用优化模型。以某铁路网络内的4个车站为例,应用该模型对4个车站的旅客列车车底运用进行了优化和分析,并运用MATLAB软件编程进行了求解,根据计算结果,在运行图不变的情况下,对车底运用进行了调整。

To improve the use efficiency of train set, according to train delay propagation, the impact of train delay on train set assignment was analyzed. The optimization model of train set assignment was proposed. Taking four stations of a railway network as examples, the train set assignment of the four stations was optimized and an- alyzed by using the model, and the results were calculated with MATLAB.
