Die Zielsetzung des Projekts bestand in der Untersuchung von Nutzenpotenzialen intelligenter Beleuchtungssysteme in der Lagerhaltung. Intelligente Beleuchtungssysteme sind in der Lage, Gänge des Lagers nutzungsabhängig auszuleuchten, sodass die Beleuchtungsintensität und damit auch der Energieverbrauch an die tatsächliche Nutzung des Lagers angepas...

The paper at hand addresses the Economic Lot Scheduling Problem (ELSP), which is concerned with finding a feasible and cost-minimal production schedule for multiple items produced in lots on a single machine. The ELSP started to attract the attention of researchers in the 1950s, where the focus was primarily on the development of simple heuristics...

Due to the role the manufacturing sector plays in the depletion of resources and the generation of greenhouse gas emissions, the consumption of energy has more and more often made it onto research agendas in the area of production planning over the last decade. The work at hand integrates energy aspects into the well-known Economic Lot Scheduling P...

This paper considers the joint economic lot size model for the special case where multiple vendors supply a single product to a single buyer. The production lots of each vendor are transferred to the buyer in batches increasing in size according to a fixed factor, where the size of the batches may differ from vendor to vendor. To coordinate the pro...

This paper studies the Economic Lot Scheduling Problem (ELSP) for the single-machine-multi-product case. In contrast to earlier research, it assumes that a lot may be split up into batches, which are then shipped individually to the consuming stage. Integrating batch shipments into the ELSP helps to reduce cycle times at the expense of higher trans...

Kurzfassung ERP-Systeme beinhalten heutzutage vielfältige Heuristiken der dynamischen Fertigungs- und Bestellmengenplanung. Allerdings variiert die Leistungsfähigkeit dieser Verfahren je nach vorliegender Bedarfsstruktur erheblich. Daher kommt der Auswahl einer geeigneten Heuristik eine wichtige Rolle zu, um Mehrkosten auf Grund ungenauer Planungen...

This paper presents an efficient procedure to extend dynamic lot-sizing heuristics that has been overlooked by inventory management literature and practice. Its intention is to show that the extension improves the results of basic heuristics significantly. We first present a comprehensive description of the extension procedure and then test its per...
