The high cost of routing infrastructure makes checking theories about larger nets a very difficult and expensive task. One possible approach to fight this problem is the use of virtual instead of physical infrastructure. OPNet- IT Guru software is a suite designed to simulate large nets and present relevant information. This allows validating extensive changes before actually implementing them on a productive network or testing theories without the overhead of a physical infrastructure.

Besides the progressive automation of internal goods traffic, there is an important area that should also be considered. This area is the carriage of goods in selected external areas. The use of driverless trucks in logistic centers can report economic efficiency. In particular, these precise control procedures require that trucks drive on predetermined paths. The general aim of this work is the adaption and evaluation of a path following control method for articulated vehicles. The differences in the kinematic behavior between trucks with one-axle trailer and semi-trailer vehicles will be emphasized. Additionally, the characteristic kinematic properties of semi-trailers for the adaptation of a control procedure will be considered. This control procedure was initially designed for trucks with one-axle trailer. It must work in forwards and backwards movements. This control process will be integrated as a closed component on the control software of the model vehicle. Thus, the geometry of the model vehicle will be specified, and the possible special cases of the control process will be discovered. The work also documents the most relevant software components of the implemented control process.
