Multi-Criteria Decision Analysis Software for Uncertain and Imprecise Information

• This paper presents a multi-criteria decision tool built on theories of uncertainty representation and evaluation. The tool supports interval probabilities, interval values (utili¬ties), interval criteria weights, as well as com¬para¬tive statements, not requiring input on single variables, but rather allowing interval statements on differences between variables. The user input is represented as constraints to the solution set of the variables representing the decision problem. The problem is then evaluated using several available evaluation methods each giving a different perspective on the decision problem modeled. Instead of applying separate sensitivity analyses on top of the evalua¬tion, it tries to incorporate the sensitivity analyses into the repre¬sentation, making uncertainty a first-class citizen in the model. The support of interval and comparative state¬ments, in addition to embedded sensitivity analyses and optionally using separate probabilistic event trees for each criterion, makes the tool, to our knowledge, the first of its kind.
