An automation project has been realized to raise the capacity, the logistic and delivery performances, to reduce the workforce needed and to optimize the use of transport vehicles. This project comprises automatic tracking of all slab displacements, done by overhead cranes and other transport vehicles. It also contains algorithms to generate optimized slab displacement commands. The position tracking of outside transport vehicles is done by GPS. The optimization algorithms will be described in some more detail, as well as the results of the complete system.
