Abstract

Amid global supply chain disruptions, seaports play a critical role in maintaining goods flow. However, operational delays remain a key challenge in port supply chains. This study systematically identifies and ranks factors contributing to these delays using a hybrid methodology that combines the Decision-Making Trial and Evaluation Laboratory (DEMATEL), the Ordinal Priority Approach (OPA), and Dynamic Grey Relational Analysis (DGRA). Five main criteria of operational delays in ports were assessed: port management, shipping and navigation, port terminal operator, customs, and cargo owners. The study's results identified 'Poor management of goods flow' and 'Customs-related issues' within port management as the most critical factors contributing to delays. Additionally, 'Ship structure' and 'Late arrival of ships' were highlighted as significant contributors under the shipping and navigation category. Notably, 'Operational cost optimization' and 'Expertise of operational staff' were found to be pivotal in the port terminal operator category, reflecting their substantial impact on operational efficiency. This study reveals interdependencies among delay factors and highlights essential intervention points to enhance port functionality. The findings suggest strategies to improve global trade efficiency and economic stability in coastal regions through better supply chain management, ultimately enhancing port resilience by enabling more robust and reliable operations during disruptions.

使用混合DEMATEL-OPA-DGRA方法系统分析和优化港口供应链的操作延迟因素

在全球供应链中断的情况下，海港在维持货物流动方面发挥着关键作用。然而，运营延迟仍然是港口供应链面临的一个关键挑战。本研究采用决策试验与评估实验室（DEMATEL）、顺序优先方法（OPA）和动态灰色关联分析（DGRA）相结合的混合方法，系统地识别和排名导致这些延误的因素。评估了港口运营延误的五个主要标准：港口管理、航运和航行、港口码头运营商、海关和货主。研究结果表明，港口管理中的“货物流动管理不善”和“海关相关问题”是导致延误的最关键因素。此外，“船舶结构”和“船舶迟到”被强调为航运和导航类别下的重要贡献者。值得注意的是，“运营成本优化”和“运营人员的专业知识”被发现是港口码头运营商类别的关键，反映了它们对运营效率的重大影响。本研究揭示了延迟因素之间的相互依赖关系，并强调了提高港口功能的必要干预点。研究结果提出了通过更好的供应链管理来提高沿海地区全球贸易效率和经济稳定的战略，最终通过在中断期间实现更稳健和可靠的运营来增强港口的抵御能力。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
