| 摘 要： | 为了提高内河航运中船闸整体通过能力，基于单航向且每个站点仅考虑一个船闸的情况，对同一条河流上的多个站点，建立了多站点航运协调调度模型，并在目标函数中引入船闸服务水平等级因子，提出了相邻船闸间的耦合约束。依据苏北运河上船舶的概率统计信息，设计了仿真优化算法对模型进行求解。仿真结果显示，闸室平均面积利用率均高于80％，船舶平均等待时间均在3h以内，对应船闸服务水平达到二级。仿真结果表明了模型和算法的有效性。

| Abstract: | In order to increase the total passing ability of inland river ship lock,a mathematical model on the co-scheduling problem of multi-port ship locks in a river is proposed.This model is based on one course of a ship lock,where the lock service level factor is introduced in the objectives and a coupling constraint between adjacent ship locks is used.According to the probabilistic information of ships in North Jiangsu Canal,a simulation optimization algorithm is designed to solve the co-scheduling problem.The ... |
