In the first article, the reference model was already explained in its essential features [1]. In the second part, the further development to a flexible reference model will be shown. The focus is on the extension to implement different source systems, the implementation of further planning tools, and the implementation of AI tools to achieve dynamic production engineering in the form of holistic and integrated factory planning. This paper explains the development of a holistic demonstrator as a proof of concept.

The increasing customization of products, which leads to higher numbers of product variants with smaller lot sizes, requires a high flexibility of manufacturing systems. These systems are subject to dynamic influences and need increasing effort for the generation of the production schedules and for the control of the processes. This paper presents an approach that addresses these challenges. First, scheduling is done by coupling an optimization heuristic with a simulation model to handle complex and stochastic manufacturing systems. Second, the simulation model is continuously adapted by real-time data from the shop floor. If, e.g., a machine goes down or a rush order appears, the simulation model and consequently the scheduling model is updated and the optimization heuristic adjusts an existing schedule or generates a new one. This approach uses real-time data provided by future cyber-physical systems to integrate scheduling and control and to manage the dynamics of highly flexible ...
