Abstract:

The development of information technology including blockchain provides the opportunity for information sharing and improves collaborative operation among terminals. To solve the disruption in berth allocation with unshared information, this paper proposes a mechanism with information sharing among terminals, which contains sharing data, access permission, and updating process of all the participants. Focusing on the operation pattern and method of dynamic berth scheduling, it discusses the influence of information sharing on the turnaround time of all the vessels, with respect to the degree of participants’ involvement, timeliness, etc. The numerical experiments demonstrate the advantages of information sharing, and the degree of involvement and timeliness of information plays a very important role in improving the service of the terminal. Even if it is only a little of the information shared, it can improve the efficiency of berth utilization in downstream ports, shorten the turnaround time of vessels, reduce the interference of uncertainties on berth planning, and mitigate the spread of ship delays at the present terminal.

Key words:

摘要：

区块链等信息技术的发展为上下游港口间的信息共享提供了条件，促进了港口间的协作运营。针对港口间信息不通畅、泊位计划受扰动等问题，提出上下游港口间的信息共享机制，设计了各参与方共享港口作业数据的内容、权限与更新流程，重点研究了信息共享下的动态泊位调度模式和方法，讨论了信息共享的策略、参与度以及时效性等因素对所有船舶在港周转时间的影响。数值实验验证了信息共享的效果，成员参与度、信息的时效性对提升码头服务水平具有重要作用。上游港口即使少部分信息共享，也可提升下游港口的泊位利用效率，缩短船舶在港周转时间，降低不确定性因素对港口泊位计划的干扰，减少上游港口扰动带来的蔓延性影响。
