In standard models of spatial harvesting, the resource is distributed over the complete domain and the agent is able to control the harvesting activity everywhere. In some cases, it is more realistic to assume that the resource is located at a single point and that the agent is required to...

In standard models of spatial harvesting, the resource is distributed over the complete domain and the agent is able to control the harvesting activity everywhere all the time. In some cases though, it is more realistic to assume that the resource is located at a single point in space and that...

In this paper we investigate optimal harvesting of a renewable natural resource. While in the standard approach the resource is located at a single point in space we allow for the resource to be distributed over the plane. Consequently, an agent who exploits the resource has to travel from one...

[Einführung ...] Mit der vorliegenden Studie werden überfachliche Kompetenzen mit Hilfe leitfadengestützter Interviews ermittelt. Dies ist ein erster Schritt zur Kompetenzmodellierung in diesem Bereich (Campion et al., 2011). Dazu wurden 25 Fachexperten, die zum größten Teil selbst im...
