Abstract
In this paper, we present a scenario approach and apply it to the Simonshaven case. We offer an outline in which we spell out the core notions of the scenario approach. Next, we give a summing up of criteria to assess and compare scenarios. We use examples of the Simonshaven case to illustrate how the scenario-approach works. The last section contains a discussion of the main strengths and weaknesses of the scenario approach and a brief comparison with argumentation-based and probabilistic approaches.
