基于SA-GA算法的船舶多目标航速优化研究
Research on multi-objective speed optimization of ships based on SA-GA algorithm
航速优化是船舶节能减排的重要手段，现航速优化以单目标进行导致能效和时间中权衡选择难以得到满足，针对此问题，本文提出了一种以能效和时间进行多目标航速优化的方法。首先推导了主机油耗-航速模型和能效-航速模型，油耗模型和能效模型的平均相对误差分别为0.0332%和0.0409%。然后提出了以遗传算法(Genetic Algorithm，GA)全局搜索和模拟退火算法(SimulatedAnnealing，SA)局部优化的SA-GA算法，分别以油耗和时间、…查看全部>>
Speed optimization is an important means for ships to save energy and reduce emissions. The current speed optimization is performed with a single objective, which makes it difficult to satisfy the trade-off between energy efficiency and time. To solve this problem, this paper proposes a multi-objective speed optimization method based on energy efficiency and time. Firstly, the fuel consumption-speed model and the energy efficiency-speed model of the main eng…查看全部>>
