The paper deals with the analysis of a special dynamic production and inventory model. In this model logical restrictions to fulfill an accepted constant minimal level of the production lot size are incorporated, instead of keeping setup cost in the objective function, as it is common in many...

Flexibilität wird im globalen Wettbewerb immer wichtiger. Viele Kunden erwarten kurze Lieferzeiten bei hoher Termintreue und die Fähigkeit, Produkte kurzfristig an ihre individuellen Wünsche anpassen zu können. In Industrieunternehmen wird daher neben entsprechenden organisatorischen...

This paper continues the analysis of a special uncapacitated single item lot sizing problem where a minimum order quantity restriction, instead of the setup cost, guarantees a certain level of production lots. A detailed analysis of the model and an investigation of the particularities of the...

This paper explores a single-item capacitated lot sizing problem with minimum order quantity, which plays the role of minor set-up cost. We work out the necessary and suffcient solvability conditions and apply the general dynamic programming technique to develop an O(T³) exact algorithm that is...

Das Potenzial der mit dem Paradigma 'Internet der Dinge' verbundenen Technologien und Infrastrukturen entwickelt sich schleichend aber dennoch rasant und unaufhaltsam. Die Entwicklungen zum Internet der Dinge eröffnen durchaus ambivalente Perspektiven: Den hohen wirtschaftlichen Potenzialen und...

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-item economic...

In a recent paper, Fisher et al. (2001) present a method tomitigate end-effects in lot sizing by including a valuation term for end-of-horizon inventory in the objective function of the short-horizon model. Computational tests show that the proposed method outperforms the Wagner-Whitin algorithm...

In this era of globalization we see an increase in specialization: the production chain issplit up in more and more parts and the production of these parts is outsourced to thoseplaces in the world where production is relatively cheapest and most efficient. Itimplies that transaction costs,...

The main aim of the paper is to highlight the relation between flexibility and vertical integration. To this purpose, we go through the selection of the optimal degree of vertical disintegration of a flexible firm which operates in a dynamic uncertain environment. The enterprise we model enjoys...
