Real-time combination of material flow simulation, digital twins of manufacturing cells, an AGV and a mixed-reality application

摘要

The integration of material flow simulation and digital planning solutions raises new challenges for the methodology and technical implementation of simulation models. The paper describes the use of a material flow simulation, which is controlling an AGV and interacting with digital twins of manufacturing cells. The digital twins determine the exact machining times. In addition, a mixed-reality application visualizes the entire system, while the communication via MQTT ensures a quasi-synchronous behavior of the different models and the AGV. The paper provides a literature review on similar solutions, describes the concept of our approach and specifies the technical implementation.
