We focus on designing and redesigning entire factories. To optimally connect workstations, production cells and lines together in one system, we have developed our own modeling methodology, material flow design in the factory. This area has recently been referred to as intralogistics. This concept has been defined by VDMA (Verband Deutscher Maschinen- und Anlagenbau) as a field of organization, control, implementation and optimization of the internal flow of materials, information and goods in an enterprise.
