In this study we investigate the desired level of recovery under various inventory control policies when the success of recovery is probabilistic. Recovery process is modelled as a single stage operation and recovery effort is represented by the expected time spent for it. The effect of...

We study a supply chain consisting of production-inventory systems at several locations which are coupled by a common supplier. Demand of customers arrives at each production system according to a Poisson process and is lost if the local inventory is depleted ("lost sales"). To satisfy a...

We study a production-inventory system with two customer classes with different priorities which are admitted to the system following a flexible admission control scheme. The inventory management is according to a base stock policy and arriving demand which finds the inventory depleted is lost...

Dieser Beitrag liefert eine Bestandsaufnahme der bisherigen Forschung zum organisationalen Lernen; Grundlage ist die Analyse von 125, zwischen 1963 und 1995 erschienenen Texten.

Determining supplier and optimum order of the quantity is an issue of great importance in logistics management for many companies. In this regard, it is crucial to determine the best decisions for the order quantity as well as the most suitable supplier through considering existing limitations...

"Inventory Analytics provides a comprehensive and accessible introduction to the theory and practice of inventory control - a significant research area central to supply chain planning. The book outlines the foundations of inventory systems and surveys prescriptive analytics models for...

Pervasive and ubiquitous oscillations, mapping the repetitive variation in time of a specific state, are well known as abundant phenomena in research and practice. Motivated by the success of oscillators in the modelling, analysis and control of dynamical systems, we developed a related approach...

We consider a periodic review single‐item inventory model under stochastic demand. Every m periods, in the regular order period, fixed order costs are K. In the periods in‐between, the intraperiods, higher fixed order costs of LK$L>K$ apply. The literature on optimal inventory policies under...

Insgesamt zeichnet sich zu Beginn der UN-Dekade „Bildung für nachhaltige Entwicklung“(2005-2014) in den Umweltverbänden ein stärkerer Trend zur Integration derNachhaltigkeitsperspektive in die Bildungsarbeit ab. Dies manifestiert sich in einer Änderungder Themen- und Methodenpalette der...

Die Frage nach der Bedeutung von Kultur für das Konzept nachhaltiger Entwicklung istAusgangspunkt des vorliegenden Beitrags. Zwei divergente Beobachtungen gaben Anstoßfür die Formulierung dieser Fragestellung: erstens spielte in den Formulierungen des 1987vorgelegten Brundtland-Berichts, dem...
