Im Rahmen des Forschungsprojektes TwinTraSys wird ein Digitaler Zwilling für innerbetriebliche Transportsysteme entwickelt und getestet. Der Digitale Zwilling soll unterschiedliche Entscheidungen unterstützen, beispielsweise die Ressourceneinsatzplanung. Eine Zielsetzung im Projekt ist die automatisierte Erstellung von Simulationsmodellen, die den aktuellen Systemzustand abbilden. Neben der Modellierung des Wegenetzes und der Transportressourcen ist die Abbildung der Transportsteuerung wichtig. Der Beitrag stellt einen Ansatz vor, mit dem reale Transportleitsysteme in das Simulationsmodell integriert werden können.

In crises, small and medium-sized enterprises (SMEs) are under more significant pressure than large companies. However, SMEs are more adaptable to changes caused by external influences. To leverage this strength, the focus is on increasing transparency, identifying bottlenecks in the material flow, and evaluating a defined target state of the material flow based on company-specific key performance indicators (KPIs) for sustainable production. Varieties of different methods are suitable for determining these KPIs. In this paper, a simulation-based analysis is performed to determine such indicators. For this purpose, an application example from practice illustrates these methods' applicability to increase the SMEs' adaptability to external influencing factors. First, a value stream analysis of the current state of the material flow is performed. Based on the results, suggestions for changes are given and implemented in a new optimized value stream. A simulation study compares the new value stream with the current one.

In recent years, hybrid order picking systems like Robotic Mobile Fulfilment Systems (RMFS) have become established and widely used in ecommerce. Companies from other logistics areas with different use cases often decide against investing in RMFS due to high investment risks or unknown performance benefits. This work contains a performance evaluation of three different use case configurations based on logistics areas in e-commerce and production conducted by a simulation model for multi-level RMFS with an integrated rolling planning approach. The model leads to a demonstrator supporting logistics managers in their decisionmaking. Those and other users can vary input parameters in the demonstrator, create different use case configurations, and run the simulation model to evaluate performance by key performance indicators (KPIs). The work depends on several discussions and interviews with logistics experts to define realistic use cases the logistics manager can identify.
