Abstract

This study addresses the critical challenge of enhancing inland waterway transport (IWT) resilience during disruptions, particularly considering imperfect shipper information. It proposes a dual subsidy mechanism targeting shippers and carriers to improve freight consolidation patterns. A bi-level programming model is formulated to determine optimal subsidies that encourage shippers to select optimal ports for cargo consolidation, aiming to minimize government expenditure while restoring system efficiency. The model, dealing with continuous shipper distribution, is discretized using the Finite Element Method to manage its complexity. To solve this intricate problem, a heuristic algorithm is developed. A comprehensive case study on the Yangtze River Economic Belt demonstrates the efficacy of the proposed freight consolidation subsidy mechanism. Results indicate mitigation of congestion during demand surges and effective adjustment of freight consolidation during compound disruptions, such as concurrent port and road network failures.

通过补贴提高内河货运整合在业务中断期间的弹性

本研究解决了在中断期间加强内河运输（IWT）恢复能力的关键挑战，特别是考虑到托运人信息不完善。建议建立针对托运人和承运人的双重补贴机制，以改善货运合并模式。建立了一个双层规划模型，以确定最优补贴，鼓励托运人选择最优港口进行货物集运，以减少政府支出，同时恢复系统效率。该模型处理连续的发货人分布，采用有限元法对其进行离散化，以控制其复杂性。为了解决这一复杂的问题，提出了一种启发式算法。通过对长江经济带的综合案例分析，验证了本文提出的集运补贴机制的有效性。结果表明，在需求激增期间缓解拥堵，并在复合中断期间有效调整货运整合，如并发港口和道路网络故障。

期刊介绍： The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
