The sheet metal nesting process in shipbuilding presents significant challenges in optimization and sustainability. This study explores the digitalization of this process through a collaborative system based on intelligent agents, following the MAS-CommonKADS methodology. The focus is on its conceptualization phase, which identifies and describes key actors, use cases, and interactions within the shipyard ecosystem. The proposed framework integrates human roles (production engineers and planners, operators) and software agents to enhance decision-making and efficiency. This approach not only addresses nesting optimization but also provides a scalable template for digitizing other shipyard processes. The findings demonstrate how collaborative human-agent systems can drive efficiency while supporting broader sustainability goals in manufacturing. Future work is expected to address technical implementation and validation in operational environments.
