现代煤炭港口卸车联合调度优化问题研究

Unloading joint scheduling optimization in modern coal port

现代煤炭港口由传统装卸服务向综合物流服务转型过程中,对港口整体调度的智能性与效率性要求提升到新高度,因此需要以系统论的观点解决煤炭港口的联合调度优化问题。针对影响卸车调度的关键问题,综合考虑车流集中到达、列车限制性调度等因素,以现代煤炭港口生产工艺流程为基础,重点研究现代煤炭港口卸车联合调度优化,构建以待车时间最短、作业时间最短且关联堆场作业动态的卸车联合调度优化模型(火车-翻车机-堆场联合调度优化模型),运用相应优化策略,分析优化模型,实现卸车调度各环节智能化的最优解决途径。

In the process of transformation from the traditional handling service to the comprehensive logistics service of the modem coal port, port overall scheduling requires more intelligent and efficient, so the coal port of joint scheduling optimization needs to be solved by the system theory. To counter the key problems affecting unloading scheduling, considering traffic concentration reached, train scheduling factors such as restriction, on the basis of modem coal port production process, focusing on the unloading joint scheduling optimization of modem coal ports, we build the model for the shortest waiting time, the shortest operation time, and the shortest dynamic operation time associated yard operation （ the train-ear dumper-yard joint scheduling optimization model）. Using corresponding optimization strategy, we analyze the optimization model and realize the optimal intelligent unloading scheduling of each link.
