This volume is based on a review of the evolving groundwater situation during the 1990s in a substantial number of developing nations. It aims to raise awareness of the key linkages between groundwater and rural development and to identify appropriate technical and institutional approaches for...

This paper argues that despite 50 years of empirical research, the phenomenon of social contagion is still poorly understood. Social contagion research has produced an eclectic, largely confused and jumbled body of evidence that lacks any comprehensive organising principle or conceptual...

In this paper, we propose the Electric Vehicle Routing Problem with Time Windows and Mixed Fleet (E-VRPTWMF) to optimize the routing of a mixed fleet of electric commercial vehicles (ECVs) and conventional internal combustion commercial vehicles (ICCVs). Contrary to existing routing models for...

This is a review of the literature on variants and extensions of the standard location-routing problem published since the last survey, by Nagy and Salhi, appeared in 2006. We propose a classification of problem variants, provide concise paper excerpts that convey the central ideas of each work,...

We present a location routing model that considers the requirements of real-world small package shippers. It integrates the choice between self-operating and subcontracting a depot. Furthermore, we consider the relocation costs which occur when established networks are restructured. We present a...

In der heutigen Zeit ist es wichtig mit den Ressourcen sparsam umzugehen. Deshalb wird in dieser Projektarbeit im Fach Industrial Ecology die Ressourcen- und Energieeffizienz der Hochschule Reutlingen untersucht. Mit dem Aufzeigen der Potentiale in diesem Bereich können Kosten eingespart und...

Many present markets for goods and services have highly volatile demand due to short life cycles and strong competition in saturated environments. Determination of capacity levels is difficult because capacities often need to be set long before demand realizes. In order to avoid capacity-demand...

This is a unique account of the role played by 58 figures and diagrams commonly used in economic theory. These cover a large part of mainstream economic analysis, both microeconomics and macroeconomics and also general equilibrium theory.

Am 10. und 11. Dezember 2004 veranstaltete die Akademie für Politische Bildung Tutzing eine Konferenz zu dem Thema "Wozu (heute noch) Gewerkschaften, Tarifautonomie und Flächentarifverträge". Im Mittelpunkt des ersten Tages stand die Frage nach der Reformfähigkeit bzw. -notwendigkeit des...

Matching uncertain demand with capacities is notoriously hard. Operations managers can use mix-flexible resources to shift excess demands to unused capacities. To find the optimal configuration of a mix-flexible production network, a flexibility design problem (FDP) is solved. Existing...
