Large-Scale Crew Scheduling
During the last decades, freight transportation experienced a worldwide boom. At the same time, competition increased considerably, such that efficient cost structures are indispensable for any market player. One of the main challenges a transportation company faces is the efficient employment of its personnel in operations, commonly referred to as crew scheduling. In this book the author presents solution approaches to large-scale crew scheduling. Firstly, the implementation of state-of-the-art operations research methods for a setting at a major European freight railway carrier is presented. Secondly, the author discusses acceleration techniques that make the developed algorithms applicable even in short-term contexts. While the analysis is based on European freight railway settings, the gained insights also apply to other (crew) scheduling contexts. Potential readership includes scholars and graduate students who are interested in the fields of crew scheduling and column generation as well as practitioners from transportation companies looking for new planning approaches.
Supply Chain Contract Management
In recent years, the design of contracts in supply chains has received significant attention from researchers and practitioners. Companies try to improve their profits by designing efficient contracts that ensure a high availability of the product at a low cost. In this book the author presents a quantitative approach for designing optimal supply chain contracts. Firstly, service level contracts, which are frequently used between a supplier and a manufacturer, are analyzed. For this contract type, optimal contract parameter combinations are identified that lead to a coordinated supply chain. Secondly, an optimal contract selection strategy is developed for a supply chain where a manufacturer can choose among multiple potential buyers. Potential readership includes scholars of supply chain management and management science, graduate students interested in these areas as well as interested practitioners involved in negotiating contracts.
The Value of Supply Chain Visibility when Yield is Random
This book focuses on supply chains with uncertainty due to random yields. A common assumption in such systems is that the yields are observable only after all transportation or production steps are completed. The actual yield realization however happens earlier during the process. Technological advances and stronger supply chain collaboration make it possible to observe yield realization in real time and therefore close the time gap between the event and the observation. Within this thesis optimal and heuristic policies are developed that make use of this new type of information in various supply chain settings. These policies are used to identify conditions under which real time yield information is particularly beneficial. This book is relevant to both scholars and practitioners interested in managing supply chains with random yields.
Non-Profit-Maximizing Behavior in Supply Chain Management
Non-profit-maximizing behavior in supply chain management focuses on the human component in supply chain management. It develops behavioral models that consider individual and social preferences of supply chain members in order to improve our understanding of actual decision-making in supply chain management. The author challenges the common assumption of a selfish homo economicus and introduces the human component in three experimental studies: In the first study, he examines the effect of individual risk preferences in the Newsvendor context. In the second study, a common group identity to overcome incentive conflicts in forecast sharing is studied. The third study explores underlying cognitive processes in contractual decision-making. Potential readership includes scholars and graduate students who are interested in the field of behavioral operations management and practitioners looking for behavioral aspects of decision making in supply chain management.
Optimization of Rental Systems
Logistics providers typically own large fleets of transportation vehicles such as rail cars or trucks. These fleets do not only determine to a large extent the service level the company can offer, but also make up a large part of total costs. Proper management of the fleet is therefore a crucial factor for these companies. In this book the author presents planning approaches that address the optimal management of vehicle fleets. Firstly, methods for determining the mixture of vehicle types and the optimal size of a fleet are developed. Secondly, approaches for supporting new service models such as customer segmentation are derived. Potential readership includes scholars and graduate students who are interested in the field of fleet planning and practitioners from logistics companies looking for new planning approaches.
Behavioral Supply Chain Contracting
Behavioral operations management is a new and growing research field incorporating behavioral aspects of decision making into operations management models, challenging the assumption of fully rational decision makers. Behavioral aspects include risk-aversion, mental accounting, reference points, or bounded rationality. In this book the author presents experimental and empirical studies that address behavioral decision making in the supply chain contracting context. First, different behavioral aspects are incorporated in the decision making process of a buyback and a revenue sharing contract. Second, an empirical decision maker is analyzed facing a service level contract. Potential readership includes scholars and graduate students who are interested in the field of behavioral operations management and practitioners looking for behavioral aspects of decision making in supply chain contracting context.
Order Expediting in Supply Chains
In the world of business management, most inventory models assume that open orders arrive after a lead time that cannot be controlled by the inventory manager. However, in many real world situations, inventory managers have the option to expedite open orders. Due to the lack of appropriate models, they often have to rely on sub-optimal heuristics to make expediting decisions. This book incorporates an expediting level policy in a periodic-review base-stock inventory model and shows how the optimal solution can be computed. The approaches can be implemented easily and are capable of solving large problems efficiently. While the book is mathematically rigorous, it presents important managerial insights gained from scenario analyses, using data from the service division of a global equipment manufacturer.

Güterwagenmanagement
Das Transportvolumen im Güterverkehr hat sich in den vergangenen 30 Jahren annähernd verdreifacht. Für diesen Anstieg sind unter anderem der Wegfall der europäischen Grenzen und die fortschreitende Arbeitsteilung verantwortlich. Auch in Zukunft wird das Transportvolumen weiter wachsen. Bis 2030 wird erneut ein Wachstum von 50 % erwartet. Dieses Wachstum betrifft alle Verkehrsträger. Aufgrund der angestiegenen Transportdistanzen sowie der ökologischen Vorteile nimmt auch die Bedeutung des Schienengüterverkehrs stark zu. Damit der Schienengüterverkehr diese Herausforderungen meistern kann, müssen die Prozesse effizient und effektiv gestaltet werden. Die Dissertation von Alexander Weye...
Praxishandbuch Agile Organisationsentwicklung
Unternehmen stehen heute zahlreichen Veränderungen gegenüber. Durch Agilität erreichen sie die notwendige Anpassungsfähigkeit, um auf Herausforderungen angemessen zu reagieren. Doch wie werden Unternehmen agil? Mit ihrem Buch unterstützt Judith Armbruster bei diesem Prozess. Leicht verständlich vermittelt sie die Grundlagen von Agilität und erklärt agile Werkzeuge und Praktiken. Darüber hinaus stellt sie mit der Agilen Blüte ein Modell für gelebte Veränderung vor. Die Umsetzung moderner Arbeitsweisen verdeutlicht sie anhand zahlreicher Beispiele aus der Praxis. Dabei nimmt sie besonders kleine und mittlere Unternehmen in den Blick. Zahlreiche Reflexionsfragen sowie das umfangreiche Canvas-Set ermöglichen es, die eigene Situation zu erfassen und eine agile Organisationsentwicklung im Unternehmen anzustoßen. Kurzum: ein wertvoller Impulsgeber für Agile Coaches, Unternehmer: innen, Führungskräfte und Mitarbeitende.
