摘要

本研究针对内河航道水运应急资源分配的不确定性和供需错配问题,提出了一种稳健的优化方法。为此,我们将海事风险评估与稳健优化模型相结合,并采用熵权法(EWM)--与理想解相似度排序偏好技术(TOPSIS)--层次分析法(AHP)来评估不同区域的风险。该方法能够探索海上风险与应急资源分配策略之间的关系。稳健优化法用于处理不确定性,并推导出拟议模型的稳健对应模型。我们建立了一个应急资源分配模型,该模型同时考虑了应急资源分配的经济性和及时性。我们构建了一个优化模型,并将其转化为一个易于求解的鲁棒对应模型。结果表明,所提出的方法能够适应实际场景,在合理配置资源的同时有效优化配置效果,提高救援效率。具体而言,救援时间的节省比例为 28.52% 至 92.60%,总成本的节省比例为 95.82%。我们的方法具有很大的潜力,可为海事管理中应急资源配置的相关决策提供有价值的参考。

Robust optimization method of emergency resource allocation for risk management in inland waterways
This study proposes a robust optimization method for waterborne emergency resource allocation in inland waterways that addresses the uncertainties and mismatches between supply and demand. To accomplish this, we integrate the risk evaluation of maritime with a robust optimization model and employ the Entropy Weighted Method (EWM)-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)-Analytic Hierarchy Process (AHP) method to evaluate the risk of various areas. The approach enables exploration of the relationship between maritime risk and emergency resource allocation strategy. The robust optimization method is used to deal with uncertainty and derive the robust counterpart of the proposed model. We establish an emergency resource allocation model that considers both the economy and timeliness of emergency resource allocation. We construct an optimization model and transform it into an easily solvable robust counterpart model. The results demonstrate that the proposed method can adapt to real-world scenarios, and effectively optimize the configuration effect while improving rescue efficiency under reasonable resource allocation. Specifically, the proportion of rescue time saved ranges from 28.52% to 92.60%, and the proportion of total cost saved is 95.82%. Our approach has significant potential to provide a valuable reference for decision-making related to emergency resource allocation in maritime management.
