Innovative MADM Framework for Strengthening Port Resilience Against Extreme Weather

The increasing frequency and intensity of extreme weather events pose a significant threat to global port infrastructure, disrupting operations, causing economic losses, and compromising the resilience of maritime trade networks. This study aims to address this issue by introducing the Infrastructure Assessment Tool, a decision-making framework based on Multiple Attribute Decision Making methodology, designed to systematically evaluate multiple, often conflicting, criteria in infrastructure assessments. The tool facilitates a comprehensive evaluation of port resilience by considering seven key criteria: structural integrity, road conditions, equipment availability, drainage systems, supporting building conditions, energy systems, and access routes. Data for the tool were collected through a combination of visual inspections, direct measurements, historical record analysis, and expert opinions, which were subsequently converted into a standardized Likert scale for comparative assessment. The Simple Additive Weighting method was utilized to assign relative importance to each criterion, incorporating expert judgment into the evaluation process. The tool’s effectiveness was demonstrated through a case study at Tarakan Port, Indonesia. Its flexibility and comprehensiveness enable port managers to proactively assess vulnerabilities, prioritize interventions, and implement targeted measures to strengthen resilience against extreme weather. Consequently, it contributes to ensuring the sustainability and continuous operation of ports, safeguarding their essential role in supporting global trade and economic growth.
