Salzburger Sand- und Kieswerke (SSK), the largest concrete and gravel supplier in the state of Salzburg, Austria, has changed the software for dispatching bulk goods as well as special-purpose-vehicles to DornerOptimize. The project is still in the pilot phase, but the trucks and several of the 9 connected quarries are already operational with the new dispatching software. At SSK, the planning of the concrete trucks is achieved with Dorner Software for years. In this context, a central gravel dispatching office was established in Kleßheim. The bulk-material module is one of several extensions, which allows the DornerBRM to be integrated into the DornerOptimize.
