A Note on Tornado Diagrams in Interval Decision Analysis
—The research efforts of the DECIDE Research Group have resulted in a decision tool capable of handling imprecise information in complex decision situations. Some of the research has been directed towards developing decision analytical algorithms and applying these algorithms in a graphical user interface. The decision tool takes intervals as well as comparative relations as input constraint, and is incorporating sensitivity analyses into the representation, instead of applying separate sensitivity analyses on top of the evaluation procedure. However, besides the built-in sensitivity analysis, a second form of sensitivity analysis could be useful in order to point out the most critical probabilities, values, or weights to the decision at hand. This paper deals with the problems and the implementation of interval tornado diagrams in a decision tool supporting interval probabilities, values, criteria weights, as well as comparative relations.
