Optimizing Shipyard Assembly Facilities in Indonesia Using a Multi-Criteria Decision-Making Approach

As the world’s largest archipelagic nation, Indonesia relies heavily on maritime transportation, positioning its national shipbuilding industry as a strategic sector. This study aims to determine the optimal strategy to accelerate ship construction by optimizing production facilities, with a specific focus on the assembly workshop. A Multi-Criteria Decision Making (MCDM) approach is applied to evaluate three alternative facility development strategies based on five key criteria: investment, production capacity, human resource requirements, design/layout efficiency, and space utilization. The analysis identifies Alternative 2—efficient adjustment in the number of facility units—as the most favorable option, achieving the highest performance score (0.98). These findings offer a strategic foundation for enhancing the production capacity of national shipyards from 35 to 50 blocks per month.
