Human-Сentric Production Operator Digital Twin
The goal of the project is to create a production environment that has a focus on the human operator element, and then to create a digital twin of the system with a real-time human measurement dataflow. In practice this means that our production system executes different types of production recipes and adapts to the operator's current condition. If the condition is not optimal, then the system will adapt to make the workload easier for the operator by rescheduling tasks and by involving stimuli made to ease the operators stress level. After completing a closed production loop, the next goal was to create a digital twin of the said production environment. This was done as a 3D-model of the system, which gets live data from the real-world system and visualizes the changes in the 3D-model. From the 3D-model it should also be possible to affect the real production system by, for example, trying to optimize the condition of the human with different stimuli.
The result of the project is a functioning production system that uses a human operator and measurements from the operator, robots and a small production system to manufacture different types of products, where one of the products is highly customizable and must be worked on by the operator. The production system is then visualized in the 3D-model, which can be then used to monitor the on-going production. In the 3D-model it is also possible to try and affect the condition of the human with a button that in turn activates stimuli in the real-world, which is meant to reduce the stress-level of the operator. The overall big picture of the real-world production environment is however depicted well in the 3D-model, which was the goal of this project work.
