摘　　要：根据海上舰船的实际破损情况,提出了基于遗传算法(GA)的破损进水舰船的优化扶正措施方案的计算方法;采用符号编码的方式,在GA算法中,通过在进化的不同阶段,设置大小不同的交叉及变异概率,提高进化速度,便于找到全局最优解,并编程实现。通过对实船破舱稳性扶正措施的优化并与传统方法的优化结果对比,证明了用GA优化破损船舶扶正措施的先进性和工程实用性。According to the real time condition of damaged ship at sea, the calculation method used for optimizing the righting measures of ship damaged stability is presented based on genetic algorithm in this paper. With symbol code, the different crossover rate and the mutation rate in different period of revolution in GA are established in order to speed up the revolution and to find the global optimal solution more likely. The corresponding program is implemented. The optimization results and their comparison with the ones obtained by conventional method for a full-scale ship verify that the righting measure optimization in ship damaged stability with GA is feasible.
