In this study, a discrete event model was created and used in combination with an optimization method to find the optimal production sequence at Volvo Group’s cab plant in Umeå. The optimization was performed with a heuristic approach combined with a genetic search algorithm. The result provides an optimized production sequence with an increased production performance. Potential improvements in the production flow were identified to significantly increase the throughput. Volvo Group Trucks Operations plant in Umeå is a part of Volvo Group AB and is one of the world’s largest manufacturers of heavy duty trucks. The plant in Umeå produces cab bodies and consists of Stamping and Part production, Body In White and the Paint Shop. As of today, t...
