Projekt:
Application of methods of nonlinear dynamics for the structuring and dimensioning of the logistic system in workshop systems

The logistic system in workshop systems is faced with high requirements due to repeated transportation processes to the same working systems as well as different transportation quanti-ties. This situation is additionally strengthened by dynamic effects, which affect the system performance. While by this an "external-driven" dynamics is usually understood, which is caused by changes of demand and order alterations, also an "internal-driven" dynamics can be observed in systems with a complex material flow (for example re-entrant systems) caused by nonlinear effects. This internal-driven dynamics can affect the logistic performance of the whole system negatively (varying stock-levels, rising cycle times, decreasing workload).
It is the aim of the presented research project to analyze and control the effects of the internal-driven dynamics on the mid- and long-range facility planning process. This will lead to an ad-justment of existing or the development of new methods for the organization of the logistic system in workshop systems, whereas the focus will be on the planning subtasks dimensioning and structuring.
Proper instruments for the description and control of the described internal-driven system dy-namics and its causes are the models and methods of the nonlinear dynamics. It is intended to use these also in this research project for the structuring and dimensioning of logistic systems. The verification of the obtained results will take place via the investigation and if necessary re-planning of real-world systems using the derived procedures and methods.
