What is a decision problem?
With Pr. Alexis TSOUKIÀS
The talk introduces a general framework defining decision problems out of combinations of invariants of the clients’ problems. Such an approach avoids classifying decision problems as combinations of methods, focussing instead on simple elements such as the set of alternatives, the problem statement and the preference statements (and how these can be formalised). We show that there is a finite number of archetypes of decision problems and that decision support methods can be constructed as instances of specific conditions upon the invariants. We also show how it is possible to translate equivalent decision problem formulations. Last, but not least we focus upon a long time neglected aspect of decision aiding: constructing the set of alternatives and we show how our framework helps in formalising it.
