摘　　要：求解较长时段内的船舶过闸优化调度方案以保障船舶能够通畅有序的通过三峡大坝和葛洲坝.针对目前普遍采用的全局优化方法存在的优化结果不稳定以及收敛速度慢等缺点,提出了一种滚动时域优化方法,并将联合通航调度系统分解为3个具有反馈回路的串联子系统,每个子系统都具有独立的滚动时域参数,从而构成了一个异步滚动时域方法模型,考虑到子系统调度顺序对优化性能的影响,提出了预测信息扰动强度排序的同步算法来降低预测信息的不确定性以提高解的质量.基于实际通航数据的比较测试表明了滚动时域优化方法在优化性能上优于全局优化方法,并且同步算法对提高优化性能有显著作用.The deterministic navigation co-scheduling to the two dams of the Three Gorges Project aims to find the optimal lockage scheduling to make ships＇ expedite passing through the Three Gorges Dam and the Gezhouba Dam. A rolling horizon procedure approach is proposed to change the disadvantages of instability and slow convergence in the global optimization algorithms. It is called asynchronous roll- ing horizon procedure （ARHP） and the co-scheduling system is divided into 3 series sub-systems with feedback loops and independent rolling horizon parameters. Because of the series relationship between sub-systems the order of sub-system scheduling can affect the performance of ARHP. A synchronization algorithm based on the perturbation sort of prediction information is designed to decrease this kind of affection. The test based on historical navigation data showsthat the ARHP has much better performance than the global optimization algorithm and the synchronization algorithm is effective.
