The ARGESIM C21 benchmark 'State Events and Structural-dynamic Systems' adresses difficulties that appear in the modelling and simulation of discrete systems with state and structure-changing events. The solution presented here uses Modelica and a component based approach. It shows that even though Modelica may have conceptual problems modelling such systems, it is capable to deal with all the tasks of the benchmark in a straightforward way.

Companies are under increasing pressure from global competition while at the same they need to offer flexible products to meet individual customer requirements. Therefore, modularised capital goods are designed and manufactured to meet both challenges. This paper presents an approach to identify necessary changes in the production process and summarises the changes in the automotive and aerospace industries due to modularisation. Three key findings are identified: increased outsourcing potential, production in a value creation network with specialised manufacturers and joint investments.

The transportation sector is responsible for a relevant share of the total emissions and offers great potentials. It is necessary to implement as many zero-emission mobility systems as possible in the shortest time. For fast ferries, which are a relevant transport manner for a large share of the global population, technical issues could be solved and the successful operation was demonstrated. Up to today high-speed ships have been fully individually designed because physical effects demand for an individual optimisation for each use-case. Specifically for battery electric ships the overall efficiency is crucial to ensure not only an ecological but also economical operation.With today's methods the design and production of such an individual designed ferry does take too long. To cover the rising demand, new approaches for mass production need to be established.In this paper we describe a method for designing a platform for ships with the example of a battery electric fast ferry. The focus is on the actual modularisation, as other aspects like requirements or results of our example case are published elsewhere and are therefore just included briefly.The method is validated on the world's first battery powered high-speed ferry.
