The automotive industry is faced with an increasing rate of development. Transport service providers that deal with finished vehicle distribution face major challenges with increasing volatility of the transported volumes. Because of the rigid planning structures, discrepancies between the planned orders of the client and the actually executed orders of transportation service occur ever more often. Planning uncertainties arise and planning errors increase, which leads to environmental and economic inefficiencies. The carriers are affected by low transport capacity utilization and an increase in empty kilometers. Furthermore, the advantages of sustainable transport by rail and water can only be exploited with sufficiently reliable planning. The focus of this thesis lies on the identification of potentials in the order execution and planning process of transport service providers to improve planning efficiency and effective execution of transfer orders in vehicle transportation. In the first section the thesis addresses processes, planning approaches and methods from the literature. I found that in recent years increased research effort has been expended in the area of cross-company order processing and integrated production and transportation planning. In practice, for the most part, IT applications of actors in the distribution chain are based on individual solutions, which leads to errors in data transmission and delays in the distribution process. To remedy this, standardized software solutions in the form of distribution networks and simulation models, that allow a standardized data basis, become increasingly popular in the literature. The second part of the thesis is an empirical study based on qualitative data collection with selected transportation service providers. Experiences, perspectives and potentials from real life were recorded and the results of the theoretical part analyzed as to their application in practice. Especially the lack of standards in data communication could be confirmed. In practice, in contrast to the literature, the factor "experience" had a high priority in all process steps. From the collected data I developed a visualization of reference, order processing and planning process for transport service providers, which presents a continuous view of the processes. The individual process elements are characterized in an information catalog with input data, output data, and potentials for improvement collected during research.
