摘要: 为缓解内河港口泊位资源供需时空不匹配问题,将单港泊位分配拓展到腹地高度重叠的内河港口群中,通过考虑不同港口之间的转港调度作业,探索多泊位联合配置优化策略。本文以船舶总成本和在港总时间最小化为目标,建立港口群多泊位联合配置优化模型。依据模型特点,设计改进的非支配排序遗传算法求解模型,并探讨调度实施前后的优化效果。以我国某内河流域的一个港口群为例,对配置模型和优化算法进行可行性验证。实验结果显示:实行联合配置策略的船舶总成本和在港总时间比独立配置均有所降低,且当船舶到港规模由20艘增加到80艘时,实施联合配置策略前后的成本和时间的降低比例平均分别提升至24%和40%左右。同时,当允许转港的船舶数量比例从0增加到20%时,船舶总成本和在港总时间的下降幅度较大;比例超过20%后,呈现边际递减效应。因此,需充分考虑转港调度成本,通过设置适当的转港数量阈值,提升港口群运作效率。

Abstract: In order to alleviate the time-space mismatch between the supply and demand of berth resources in inland ports, the allocation of single port berths is extended to inland ports with highly overlapping hinterlands. The optimization strategy of multi berth joint allocation is explored by considering the transfer scheduling operations between different ports. With the aim of minimizing the total cost and the total time in port, a multi-berth joint allocation optimization model for port groups is established. According to the characteristics of the model, an improved non-dominated sorting genetic algorithm is designed to solve the model, and the optimization effect before and after scheduling is discussed. Then, taking a port group in an inland river basin in China as an example, 4 groups of simulation experiments were set according to the ship arrival scale, and 12 numerical examples were randomly generated to verify the effectiveness of the model and the configuration strategy. The experimental results show that the total cost and the total time in port under the joint allocation strategy are lower than those under the independent allocation strategy, and when the size of ships arriving at port increases from 20 to 80, the reduction ratio of cost and time before and after the implementation of the joint allocation strategy increases to about 24% and 40%, respectively. Meanwhile, when the proportion of the number of ships allowed to transport increases from 0 to 20%, the total cost of ships and the total time in port decrease greatly. After the proportion exceeds 20%, a marginal diminishing effect occurs. Therefore, considering the cost of port transfer, setting an appropriate transfer quantity threshold can improve the operation efficiency of the port group.

Key words: waterway transportation, joint allocation strategy, non-dominated sorting genetic algorithm, inland port group, multi objective optimization
