Abstract

Kanban is a representative control policy pursuing cost-efficient features for the material flow system. However, the Kanban mechanism increases the system vulnerability especially when the environment is uncertain. Therefore, we proposed a robust Kanban system model for the supply chain system based on the Kanban mechanism. The model can use robust approaches from strategic, tactical, and operational levels to deal with the risks in an uncertain environment.

Abstract

Efficient inbound networks in the European automotive industry rely on a set of different transport concepts including milk runs - understood as regularly scheduled pickup tours. The complexity of designing such a mixed network makes decision support necessary: In this book we provide definitions, mathematical models and a solution method for the Milk Run Design problem and introduce indicators assessing the performance of established milk runs in relation to alternative transport concepts.

Abstract

"Supply-chain preparedness means to design inter-organisational structures,&#xD;to organise supply-chain resources, and to plan and train to ensure efficient&#xD;response if this is called for. Acknowledging that supply chains are made up of&#xD;two or more organisations, and that interaction describes relations between two or&#xD;more actors, the purpose of this research is to explore whether the introduction of&#xD;the concept of interaction (samhandling) to supply-chain thinking adds to our understanding&#xD;of efficiency and the effectiveness of logistics preparedness.&#xD;We position our work along three dimensions: a profit – non-profit classification,&#xD;a descriptive – normative dichotomy, and a micro – macro continuum. Information&#xD;was retrieved both through semi-structured interviews and by studying secondary&#xD;sources. Interaction and preparedness is assessed through an empirical case: the&#xD;operation Atalanta. By applying interactional indicators, enablers and barriers to&#xD;relationship success can be studied at both micro, meso, and macro levels. Without&#xD;understanding the mechanisms leading to interactional competence, success (or&#xD;the lack thereof) in supply-chain preparedness is difficult to address properly. Thus,&#xD;managers need to assess the interactional constructs at all levels when planning and&#xD;training for preparedness."&#xD;

Abstract

Value chains of bio-based chemicals are very complex. Hence, a strategic decision support tool for bioeconomic site and logistics planning is developed. It includes an integrated model and three sub-models: optimization for the locations and capacities of pretreatment plants, technical for technical and economic evaluations, risk for the evaluation of uncertainties. As a result, the model suggests a nearly optimal location and the associated logistic network for the production of biochemicals.

Abstract

Companies with high-performing supply chains enjoy essential competitive ad- vantages. However, supply chain management faces an environment of rising risk that endangers these competitive advantages. One of the reasons is to outsource parts of their business. This bears the risk of significantly increased lead times and lead time variability. It is the impact of lead time variability on inventory management that is the central aspect of this book. It describes a mathematical model for dual sourcing with two reorder points, shows the deviation between stochastic and deterministic calculations in a sensitivity analysis, and investigates different relaxations of a traditional dual-sourcing policy.

Abstract

Ein entscheidender Erfolgsfaktor jeder Supply Chain ist das adäquate Design ihrer Leistungserstellungsprozesse. Da diese Prozesse regelmäßig durch einen hohen Grad an Komplexität gekennzeichnet sind, stellt deren Gestaltung eine große Herausforderung dar. In dieser Forschungsarbeit wird deshalb die Frage behandelt, wie komplexe Leitungserstellungsprozesse einer Supply Chain effektiv und effizient verbessert werden können. Dazu wird eine systematische Vorgehensweise für die Analyse und Bewertung von Supply Chain Prozessen vorgestellt und im Rahmen einer Fallstudie auf eine reale Logistikkette in der Elektronikindustrie angewandt. Bei der Prozessanalyse wird eine Reduktion der Komplexität durch eine Kombination von analytischen Methoden und Simulation erzielt, sodass nicht nur die Validität der Ergebnisse, sondern auch die praktische Umsetzbarkeit gewährleistet ist. Die Bewertung von alternativen Prozessdesigns erfolgt multikriteriell und strategiebasierend, damit sowohl Zielkonflikte als auch die verfolgte Strategie der Logistikkette Berücksichtigung finden. Generell spielt die Wahl des marktbezogenen Produktionstyps (z.B. Make-to-Order, Make-to-Stock) bei der Verbesserung von Supply Chain Prozessen eine entscheidende Rolle. Daher wird auf diesen Aspekt besonders eingegangen, wobei der hybride Produktionstyp Make-to-Forecast in einem Supply Chain-Kontext in der Fallstudie implementiert wird.

Abstract

Diese Arbeit wurde mit dem Ernst-Zander-Preis 2005 der Ruhr-Universität Bochum ausgezeichnet.
Das Supply Chain Design als strategisches Supply Chain Management beinhaltet als wesentlichen Aspekt die Konfiguration der Supply Chain. Dabei sind die über eine Preisminimierung hinausgehenden Auswahlkriterien der Zulieferer sowie die aus dem langfristigen Planungshorizont der Fragestellung resultierende Unsicherheit geeignet zu berücksichtigen. In dieser Arbeit werden die vielfältigen betriebswirtschaftlichen Aspekte des Supply Chain Design umfassend diskutiert und ein Kriterienkatalog zur Auswahl von Zulieferern entwickelt. Die Unsicherheit wird mit Hilfe des neu entwickelten Konzeptes der Zielrobustheit abgebildet. Die Planungsentscheidungen im Rahmen des Supply Chain Design können durch das vorgestellte Vorgehen unterstützt und in ihren Konsequenzen quantifiziert werden.

Abstract

The joint symposium of The Omega-3 Centre and the Australasian Section American Oil Chemists Society; Recent Advances in Omega-3: Health Benefits, Sources, Products and Bioavailability, was held November 7, 2013 in Newcastle, NSW, Australia. Over 115 attendees received new information on a range of health benefits, aquaculture as a sustainable source of supply, and current and potential new and novel sources of these essential omega-3 long-chain (LC, ≥C20) polyunsaturated fatty acid nutrients (also termed LC omega-3). The theme of “Food versus Fuel” was an inspired way to present a vast array of emerging and ground breaking Omega-3 research that has application across many disciplines. Eleven papers submitted following from the Omega-3 Symposium are published in this Special Issue volume, with topics covered including: an update on the use of the Omega-3 Index (O3I), the effects of dosage and concurrent intake of vitamins/minerals on omega-3 incorporation into red blood cells, the possible use of the O3I as a measure of risk for adiposity, the need for and progress with new land plant sources of docosahexaenoic acid (DHA, 22:6ω3), the current status of farmed Australian and New Zealand fish, and also supplements, in terms of their LC omega-3 and persistent organic pollutants (POP) content, progress with cheap carbon sources in the culture of DHA-producing single cell organisms, a detailed examination of the lipids of the New Zealand Greenshell mussel, and a pilot investigation of the purification of New Zealand hoki liver oil by short path distillation. The selection of papers in this Special Issue collectively highlights a range of forward looking and also new and including positive scientific outcomes occurring in the omega-3 field. [...]

Abstract

Vitamin E is the major lipid-soluble antioxidant in the cell antioxidant system and is exclusively obtained from the diet. In 1922, vitamin E was discovered as a dietary factor essential for reproduction in rats. Meanwhile, vitamin E has revealed many more important molecular properties, such as the scavenging of reactive oxygen and nitrogen species with consequent prevention of the oxidative damage associated with many diseases. In addition, the modulation of signal transduction and gene expression in antioxidant and non-antioxidant manners was shown for vitamin E.This Special Issue highlights some of the recent advances in vitamin E research, showing on the one hand the status quo and providing, on the other hand, new insights into functions and physiological relevance. Thus, the current knowledge of tocochromanol biosynthesis in plants and future challenges regarding the understanding of its regulation are presented. Another paper describes the fate of vitamin E in the human gastrointestinal lumen during digestion. During the metabolism of vitamin E, the long-chain metabolites 13’-hydroxychromanol and 13’-carboxychromanol are formed by oxidative modification of the side-chain. Their occurrence in human serum indicates a physiological relevance. Another paper describes the membrane distribution of α-tocopherol in brain regions of adult rhesus monkeys, also looking for associations between membrane α-tocopherol and the content of polyunsaturated fatty acids.
