摘要
在不改变车底配属制的前提下,以车底在配属站和折返站的接续时刻和停留时间、车底与列车对在接续时间间隔和车底要求的匹配度、车底运用与到发线运用和整备线运用的协同性等为约束条件,以始发和终到旅客列车的车底不必要在站停留时间最小为目标函数,建立基于既定运行详图的旅客列车车底套用优化模型。将模拟退火算法参数的设定描述为随机优化问题,采用序优化巢分区算法设定模拟退火算法参数;在此基础上,设计求解优化模型的模拟退火算法。以郑州车站为例,验证模型和算法的有效性。结果表明:运用给出的模型和算法得到的车底套用方案,减少了所需车底数量和车底在配属站及折返站的停留时间,提高了车底运用效率。车底套用后尚需进一步解决某些旅客列车晚点对车底接续的影响、因车底不匹配对中短途列车上座率的影响、旅客列车密集到达和发车时间段出现的站台拥挤等问题。
In the precondition of not changing the attachment system of passenger train stock,an optimization model for the assignment of passenger train stock was developed based on the given train diagram with the minimum unnecessary staying time of passenger train stock at both the departure and terminal stations as the objective function.Such constraints were considered as the connecting time and staying time of passenger train stock at the attached and switchback stations,the matching degree of connecting time interval and train stock requirement between train stock and passenger train as well as the cooperativity among the assignments of train stock,arrival and departure tracks and servicing siding as well.The parameter setting of simulated annealing algorithm was described as stochastic optimization problem,and ordinal optimization based nested partition algorithm was adopted to work out the parameters of simulated annealing algorithm.On this basis,the simulated annealing algorithm was designed to solve this optimization model.Taking Zhengzhou Station as an example,a case study has been carried out to verify the validity of the model and algorithms.The results show that the scheme for the assignment of passenger train stock obtained from the above mentioned model and algorithms can reduce the required number of passenger train stock and the staying time of passenger train stock at the attached and switchback stations,and improve the operation efficiency of passenger train stock.The practical problems need to be further solved after the assignment of train stock completed,such as the influence of delayed passenger train on the connecting of passenger train stock,the influence of the mismatching of passenger train stock on the occupancy rate of short and middle distance trains,and the platform crowded during the dense arrival and departure of passenger trains.
