Through individualized products, competitive advantages can be realized in volume markets. This leads to the emergence of a diverse series production in many industries, with very specific requirements for production management. Since all activities are tied to customer orders, operational performance is primarily influenced by the order-related planning system. This necessitates a profound understanding of the associated planning tasks of order acceptance and production scheduling. Based on a general framework and the analysis of the decision-making situation, Thomas Volling develops a quantitative planning system for order-related planning in diverse series production. To validate the approach, he presents the results of a simulation-based study that highlights the fundamental characteristics of the system.
