In a project for Astilleros Cardama (Cardama Shipyards), the Integrated Group for Engineered Research researched methods for sequencing the operations of both assembly and production in a workshop to reduce ship construction and repair time, minimise risk during assembly operations and lower operating costs from improper assembly and resource consumption. By generating systematic procedures for operational organisation, tracking and tracing different elements was facilitated and the implementation of quality systems promoted.
Using results from a detailed study of the operations taking place in the yard as well as precedence relations between tasks and the resource constraints involved, an ExtendSim model was built that included the variability and uncertainty caused by the arrival of new orders with different characteristics.
The model helped reduce production times and improve product quality. Moreover, the safety of workers increased, while the consumption of resources gets reduced.
