Abstract
At present, make-to-order production systems face layout and production planning challenges due to unpredictable and fluctuating customer demand. Traditional planning approaches are static and limited in its ability to evaluate potential "To-be" scenarios for future production scaling. Therefore, Digital Twin based factory and production planning seems to be a promising approach owing to its dynamic characteristics. Hence, this case study proposes a Digital Twin Prototype development approach for effective factory and production planning. This approach integrates assembly line balancing and digital factory planning to implement the “what ifs” scenarios and further lays the foundation to build simulation based Digital Twin.
