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...

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...

Application of multisource feedback (MSF) increased dramatically and became widespread globally in the past two decades, but there was little conceptual work regarding self-other agreement and few empirical studies investigated self-other agreement in other cultural settings. This study...

There is a growing focus on sustainability in corporate objectives. A key approach to managing and implementing sustainability is through operations management. Sustainable operations hold the key to increased profitability and effective management of environmental issues. Among the business...

Studies in newsvendor decision-making have shown that human decisions systematically deviate from analytical solutions found in many utility models of the single period problem (SPP). Yet for the most part the impacts of this human decision bias in systems of newsvendor type products have not...

This thesis studies inventory control with risk of major supply chain disruptions, specifically border closures and congestion. We first investigate an inventory system in which the probability distributions of order leadtimes are dependent on the state of an exogenous Markov process; we will...

This thesis studies three problems related to inventory control.The first problem is motivated by the need to eliminate thebullwhip effect in a supply chain. An important source of thiseffect is the inventory control policy, which is originallydesigned to smooth production in response to demand...

Uncertainty is a norm in business decisions. In this research, we focus on the inventory decisions for companies with uncertain customer demands. We first investigate forward buying strategies for single stage inventory decisions. The situation is common in commodity industry where prices often...

In equipment-intensive industries such as truck manufacturing, electronics manufacturing, photo copiers,and airliners, service parts are often slow moving items for which, in some cases, the transshipment timeis not negligible. However, this aspect is hardly considered in the existing spare...
