    A Study of Archipelago Berth Allocation Based on Hybrid Particle Swarm Optimization Algorithm

    • 摘要:  泊位分配是提高港口运营效率的关键。针对群岛泊位分配问题,以船舶总在港时间为优化目标,构建了群岛泊位分配问题模型,并提出了一种混合粒子群算法进行求解。该算法在更新粒子状态时加入模拟退火和免疫调节操作,增强了算法的全局搜索能力。实验结果表明,混合粒子群算法在求解群岛泊位分配问题时,具有较好的优化性能,验证了算法的有效性和可行性。

       

      Abstract: Berth allocation is the key to improving the efficiency of port operation. Aiming at the archipelago berth allocation, a model is established with minimum waiting time of ships as objective, and a hybrid particle swarm optimization (HPSO) algorithm proposed. In HPSO, simulated annealing (GA) and artificial immunity (AI) are applied to update the state of particles, thus improving the global optimization of HPSO. Numerical experiment results show that, the HPSO is an effective and feasible algorithm for solving the archipelago berth allocation problem.
