New Publication in "International Journal of Production Research"

We are pleased to publish a new paper in the International Journal of Production Research entitled "An iterated local search for customer order scheduling in additive manufacturing". In the article, Benedikt Zipfel, Janis Neufeld, and Udo Buscher investigate the impact of a customer-centric view on the integrated scheduling problem in additive manufacturing and develop a metaheuristic. Furthermore, they show the potential of an order-related objective function compared to conventional objective functions.

Abstract:

This paper studies the customer order scheduling problem in the context of additive manufacturing. The study discusses an integrated problem involving the nesting of parts as well as the scheduling of batches of nested parts onto unrelated parallel machines. A mixed-integer programming model is presented, based on existing formulations from the literature, that integrates different materials and sequence-dependent setup times. Additionally, a metaheuristic based on an iterated local search is proposed for the problem configuration under consideration. Focusing on minimizing the total weighted tardiness of orders, the efficiency of the heuristic approach is evaluated using comprehensive test data. Further, we show the importance of the considered order-related objective by using qualitative analysis.
