Simulation

Professor Bernd Scholz-Reiter studied industrial engineering at the Technical University of Berlin. After several positions in Germany and abroad, he accepted the call to the University of Bremen in 2000, where he initially held the professorship of Planning and Control of Production Systems in the Department of Production Engineering. From 2002 to 2012, he also headed the Bremen Institute for Production and Logistics (BIBA). From 2012 to 2022, Bernd Scholz-Reiter was rector of the University of Bremen.

Efficiency in container terminal operations is key for competitiveness. Many large German terminals use the flexible but relatively risk-laden manned straddle carriers (SCs). The research project STRADegy evaluated the reliability and profitability of automated SCs in northern-German container terminals via a combination of a pilot installation and an emulation at the container terminal in Wilhelmshaven. Parallel to that, rollout-guidelines were developed. This paper introduces central results regarding a successful rollout of auto-SC-systems.

Efficient product development can be a decisive factor in a company’s competition - it quickly falls behind who has to cope without simulation technologies. For large companies, these have long since become part of everyday life. But for small and medium-sized companies, they often remain wishful thinking for reasons of capacity and know-how. But: They, too, can benefit from the advantages of simulation with the right support and appropriate training programs.

Designing and simulating complex mechatronic and distributed intelligent systems requires a unified system modeling and programming language. This paper presents JavaScript as a unified modeling and programming language by extending JavaScript with a semantic type system JST to bridge the gap between models and implementations. The result is the JS+ Superset language, which combines typing, modeling and programming. Different model domains and their relation to the JS+ programming model including some generic transformation rules are shown using the example of a sensory material. Finally, the multidomain simulation tool SEJAM is introduced, which combines physical and data processing simulation with agents.

German sea and inland ports are of outstanding importance for Germany as a base for manufacturing and logistics. In the last decades, the port sector underwent several structural changes. Currently, the expected autonomation and digitalization of the entire supply chain create entirely new challenges for the port industry. In this context, the present article describes a planning approach for the development of an automated straddle carrier in northern German seaports. To evaluate both the reliability and the profitability of such an automated system, a planning approach, consisting of two fundamental steps, was chosen: (1) At first, in order to perform prototypical experiments, a pilot installation will be established in the area of the container terminal in Wilhelmshaven (CTW). (2) Based on this, the system’s suitability for the operative conditions in a mega container terminal is evaluated using a simulation and emulationbased planning approach.
