Die vorliegende Arbeit besch?ftigt sich mit der Gestaltung von Service-Netzwerken. Das Design solcher komplexen Netzwerke, insbesondere von gro?en Liniennetzen, bietet gro?e Potentiale zur Kostensenkung und Verbesserung der Service-Qualit?t. Durch eine Einsparung von wenigen Prozentpunkten kann...

Even though the question as to whether optimal organizational structures exist has been asked repeatedly, organization theory has not been able to answer it in general form. Over time, several useful heuristic principles to direct the structuring of organizationshave emerged.(...)

TWe perform a novel analysis of the fitness landscape of thejob-shop scheduling problem (JSP). In contrast to other well-known combinatorial optimization problems, we show that the landscape of the JSP is non-regular, in that the connectivity of solutions is variable.

One of the major cost factors in car manufacturing is the painting of bodyand other parts such as wing or bonnet. Surprisingly, the painting may beeven more expensive than the body itself. From this point of view it is clearthat car manufacturers need to observe the painting process carefully to...

In this paper, we consider an investor who plays in a market that involves a risky asset whose instantaneous rate of return changes at unknown random times. This return rate is assumed to follow the law of a Compound Poisson Process. We construct optimal mathematical strategies in this context...

We develop an algorithm to compute asset allocations for Kahneman and Tversky's (1979) prospect theory. An application to benchmark data as in Fama and French (1992) shows that the equity premium puzzle is resolved for parameter values similar to those found in the laboratory experiments of...
