CITIC, together with CITENI, is leading the development of an intelligent model that optimises shipbuilding

Researchers at CITIC, a research centre at the University of A Coruña and a member of the CIGUS Network—an initiative promoted by the Xunta de Galicia that brings together research centres recognised for their scientific excellence—have developed a pioneering tool that improves planning processes in shipyards and, for the first time, incorporates the actual hull assembly strategy.

The study, carried out in collaboration with CITENI (Research Centre for Naval and Industrial Technologies) at the University of A Coruña, was published in the International Journal of Production Research, one of the leading journals in the field of industrial engineering.

This joint work marks a significant advancement in ship production planning, integrating real operational variables and offering an adaptive perspective on manufacturing processes. The proposed methodology applies Constraint Programming techniques to automatically generate more efficient assembly plans, reducing production times and optimising the use of available resources.

José A. Becerra, a researcher at CITIC and a key contributor to the development of this innovative model, played a pivotal role in its computational design and implementation. His work draws on the centre’s expertise in advanced artificial intelligence and optimisation techniques, ensuring the tool aligns with the highest standards in ICT applied to industry.

The model is based on algorithms that consider real-world constraints in shipyards: crane availability, delivery deadlines, temporary storage capacity, assembly strategies, and workforce availability. Combining these factors allows for much more accurate planning, helping to avoid bottlenecks and make the most of available resources.

According to CITIC, one of the model’s most innovative features is its ability to adapt to different real-world hull assembly strategies—whether in rows, columns, or pyramid formations—and to automatically tailor planning to the most suitable option based on each shipyard’s resources and objectives.

This achievement is the result of interdisciplinary collaboration between CITIC and CITENI, within the ecosystem of the University of A Coruña and in connection with the UDC-Navantia Joint Research Centre (CEMI). The developed tool represents a major step in transferring knowledge to strategic industries, reinforcing CITIC’s commitment to the practical application of ICT in high-value sectors.
