Risk Based Decision Making: Three Examples of Practical Application Tools

The paper discusses three ongoing or recently finalised projects carried out at the Lund University Centre for Risk Analysis and Management (LUCRAM). The first section discusses decision making situations involving extreme or catastrophic events and the application of a newly developed decision analysis method. The second chapter discusses the framework and the methodological aspects of a computer based decision analysis tool for assessing and managing local or municipal vulnerability. The third part of the paper, finally, presents a comparative uncertainty analysis of a risk study of an ammonia storage facility employing a number of methods: Monte Carlo analysis, Interval analysis, Fuzzy arithmetic and Probability bounds theory.
