Item type:Publication, Access status: with files , The key to improving the trade-off between service and inventory levels in make-to-stock production: sequencing and capacity controlSafety stocks play an important role in make-to-stock production, since they ensure supply to customers despite uncertainties in production and demand. A large literature exists on safety stock calculations, but it typically assumes exogenous stationary replenishment times. In most real-world settings, capacity is a constraint leading to non-stationary replenishment times that are under the control of management. In response, we design a new production planning and control approach for make-to-stock production based on cumulative quantity logic and show how companies can use sequencing and capacity control based on current demand to improve customer supply and to reduce safety stocks. Results from discrete event simulations highlight the potential of the new approach and indicate that the proposed manufacturing control reacts robustly against wrongly set planned demand rates. This contributes to theory, while the comparatively low information processing requirements and robustness of the approach make it an important potential solution for practice.Publicationtype: Journal Article19 15 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Material flow control in make-to-stock production systems : an assessment of order generation, order release and production authorization by simulationMaterial flow control (MFC) is a key element of production planning and control. The literature typically categorizes different MFC methods according to how MFC is realized. This distinction overlooks that MFC decisions can be subdivided into three independent tasks that are executed as orders progress through the system: (i) order generation, (ii) order release, and (iii) production authorization. MFC methods are typically designed for only one of these three tasks, which leaves a large part of the order flow uncontrolled. This study therefore not only provides a new categorization of MFC methods, but also argues for the simultaneous application (or the combining) of three different MFC methods for order generation, order release, and production authorization. To support this argument, the performance effects of an integrated MFC approach are evaluated. Findings show that each individual MFC method impacts different performance metrics, which can be explained by the presence of a hierarchy of workloads, where each workload level constrains the succeeding hierarchical level. Each MFC method has a main impact on a different workload. This has important implications for the design of MFC methods and extends recent literature on hierarchical production planning and control systems.Publicationtype: Journal Article29 77
