基于蜂群算法的船舶压载水调配优化分析

Research on optimization of ship ballast water allocation based on bee colony algorithm

重型起吊船舶作业过程中会引起船舶倾斜,压载水系统通过调节全船压载舱舱室压载水的注入、排出或调驳确保船舶稳定性。基于船舶静力学和蜂群算法建立了船舶压载水调配优化数学模型,以船体的稳定性为约束条件,压载水总调配量为目标函数进行优化研究,通过对目标案例进行解算分析,该优化方案极大的降低了压载水的调配量,提高了压载水调配效率,该算法通用性强可为船舶自动化压载系统研制提供理论支持,在保证船舶压载安全性和稳定性的前提下实现船舶压载自动化。

During the operation of lifting vessel,the ship will be tilted.The ballast water system ensures the stability of the ship by adjusting the injection,discharge or transferring of ballast water in the ballast cabin of the whole ship.In this paper,based on ship statics and Bee Colony Algorithm,the mathematical model of ship ballast water allocation is established.Taking the stability of ship as constraint condition and the total allocation of ballast water as objective function,the optimization scheme greatly reduces the allocation of ballast water and improves the efficiency of ballast water allocation by solving and analyzing the target case.The algorithm can provide theoretical support for the development of ship automatic ballast system and ensure the stability and safety of ship operation.
