Implementation of a Petri-net based Digital Twin for the development procedure of an Electric Vehicle

In the current work the development procedure (design, manufacture and assembly) of an electric vehicle is considered. Uncertainties make difficult to follow initial time plan, so monitoring of the development procedure is necessary. To handle delays a method using Petri nets to model the tasks of the development procedure and their dependencies is introduced. The model is not used offline as a passive element but is connected and interacts with the physical system (development procedure). Based on the information exchange between physical and digital system, alternative ways to overcome delays are studied and the optimal solution is calculated, tested and applied. Results are provided according to different scenarios, in order to show the efficiency and applicability of the proposed method.
