摘要

码头拖曳和驳船作业在港口内的货物转运中起着至关重要的作用,特别是在复杂的水道中。驳船和拖船的调度受航速等多种因素的影响,作业计划必须考虑航道交通的约束。此外,转运系统还涉及建造和操作泊位、转运设备、驳船、拖船和其他资源。有效的调度和资源规划对实现可持续性至关重要。为了说明这一点,我们分析了一个实际案例的河口驳船过程。我们利用Anylogic平台模拟矿石码头装载、内河运输、海运转运的全过程。此外,我们采用基于仿真的优化方法来提高系统的性能。我们的案例研究产生了有价值的管理见解,包括:(1)识别和优化与运输速度和资源分配相关的关键变量;(2)特定的拖轮调度规则已被验证在效率和排放方面优于其他选择;(3)已确定兴建及启用另一个码头的潜在效益。我们的研究为矿石码头工程项目的船舶调度和资源规划决策提供了定量支持。

Simulation and optimization of transfer system for ore terminal with complex waterways

Terminal towing and barging operations play a critical role in cargo transfer within ports, especially in complex waterways. Scheduling of barges and tugs is influenced by various factors, such as speed, and the operation planning must consider the constraints of channel traffic. Additionally, the transfer system involves constructing and operating berths, transshipment equipment, barges, tugboats, and other resources. Effective scheduling and resource planning are crucial for achieving sustainability. To illustrate this point, we analyze the estuary barging process in a real-world case. We utilize the Anylogic platform to simulate the entire process of ore terminal loading, river transportation, and sea transshipment. Furthermore, we employ simulation-based optimization methods to enhance the system’s performance. Our case study has yielded valuable management insights, including: (1) Key variables related to shipping speeds and resource allocation are identified and optimized; (2) A specific tug dispatch rule has been verified to outperform other options in terms of efficiency and emissions; (3) The potential benefits of constructing and enabling an additional terminal have been identified. Our exploration provides quantitative support for decision-making related to vessel scheduling and resource planning in engineering projects for ore terminals.
