【摘要】 基于放射形专用线取送车作业的特点,针对非直达车流取送车问题中,多列列车相继到达车站时,对如何确定合理的取送车顺序进行分析。将取送车作业作为一个系统进行整体考虑,以货车在站停留的总车小时消耗最小为优化目标,建立数学模型。利用此模型,可以得到在多列列车相继到达车站情况下的取送车顺序、取送作业的具体时刻和取送作业次数。针对模型的具体特点,设计求解的编码方式,并采用基于云模型的参数自适应蚁群遗传算法进行仿真,结果表明了模型和算法的有效性。更多还原

【Abstract】 On the basis of the characters of taking-out and placing-in shunting on actinoid private lines,the best schedule of taking-out and placing-in of wagons of several non-through trains arriving at the railway station successively is analyzed.Collection and delivery shunting being treated as within one integrated system,a mathematical model is established with the objective to minimize the detention vehicle-hours of wagons at a station.Through calculating the model,the optimal sequence,time and number of collection and delivery shunting operations can be found.The model taking advantage of a skillful encoding method is designed and called ACGA with self-adaptation adjustment of parameters based on cloud models.The simulation result shows the validity of the model and the algorithm.更多还原
