摘　　要：针对既有线繁忙铁路客运站,结合其站型特点与列车运行时刻表,将调机走行进路、时间和列车接发进路排列作为决策对象,研究铁路客运站调机运用与列车接发进路的协同优化。以列车接发车进路的合理选择、车站咽喉道岔及到发线等设施的利用及相容性作为约束条件,建立咽喉道岔、到发线运用效率最大化和调机出入段作业接续时间最少、走行距离最短为目标的协同优化模型。以模拟退火算法为基本思想,设计了所建立模型的求解算法。算例计算结果表明:所建立的优化模型及求解算法,计算速度快,结果正确合理,可为铁路客运站的日常行车组织工作提供科学的决策依据。Based on specific station typecharacteristics and train timetable,vehicle running route,time and train receiving and departure routes were chosen as decision objects,this paper studied the comprehensive optimization method of vehicle operation and train receiving and departure routes.The reasonable selection of train receiving and departure routes,the utilization and coordination of station throat turnouts,arrival departure tracks and other facilities as constraintswere conducted.The integrated optimization model was established to maximize the operation efficiency of throat switch and arrival departure trackand to minimize the connection time and travel distance of vehicle in and out of the warehouse;Based onthe simulated annealing algorithm,the algorithm of solving the model was designed.The calculation results show that,the optimization method and algorithm are fast,as well as the results are correct and reasonable,which can provide scientific decision-making basis for the daily traffic organization of passenger station.
