Random yields from production are often present in manufacturing systems and there are several ways that this can be modeled. In disassembly planning, the yield uncertainty in harvesting parts from cores can be modeled as either stochastically proportional or binomial, two of these alternatives....

Despite the fact that career attitudes and their influence on career outcomes is widely researched in the field of occupations and careers, little is known about the influence of cultural norms and values on career attitudes. We propose that national cultural dimensions influence students’...

Mit dem von P. Nyhuis und H.-P. Wiendahl entwickelten Konzept der logistischen Kennlinien ist das Ziel verbunden, den Zusammenhang zwischen verschiedenen Kenngrößen eines logistischen Systems mit einem einfachen Funktionsverlauf hinreichend genau abzubilden. Im Rahmen von Lagerkennlinien soll...

In the area of reverse logistics, remanufacturing has been proven to be a valu- able option for product recovery. In many industries, each step of the products’ recovery is carried out in lot sizes which leads to the assumption that for each of the different recovery steps some kind of fixed...

Using data of Swiss referenda from 1981 to 1999, this paper presents new empirical results which allow us to discriminate better between the decision and mobilisation hypotheses of electoral participation. First, theoretical considerations which lead to these hypotheses are presented as well as...

An increasing number of member countries of the European Union (EU) is heading for ratification through referendum of the yet to be adopted constitution for Europe. Such popular votes will add an additional ratification constraint and empirical models will require information on the positions of...

We test the lower bound for a static remanufacturing system with returns proposed by Feng and Viswanathan (2014) against two heuristics proposed by Choi et al. (2007) and Schulz and Voigt (2014). A numerical study with 81,000 instances concludes that the lower bound always holds for the Choi...

An effective planning of lot sizes is a key strategy to efficiently manage a combined manufacturing/remanufacturing system in the presence of substantial setup costs. Due to its complex interdependencies, optimal policies and solutions have not been identified so far, but several heuristic...

The term urban sprawl is often used to describe apparent inefficiencies of spatial development, including disproportionate growth of urban areas and excessive leapfrog development. In Switzerland, where open space is a scare resource, sprawl takes place all over the country. It goes at the...
