Problematics as Guides in Decision Aiding
In Section 6.1, we define and illustrate four reference problematics — P.α, P.β, P.γ, P.δ. The objective of P.α is to aid the decision maker by the choice of a subset that is as small as possible so that a single action can eventually be chosen. This subset contains “best” actions (optima) or, perhaps, “satisfactory” actions (satisficing solutions). The result of P.α is a choice or a selection procedure.
The objective of P.β is to aid the decision maker by a sorting that leads to an assignment of each action to a category, where the categories are defined beforehand as a function of certain norms that deal with the ultimate fate of the actions that will be assigned to them. The result of P.β is a sorting or an assignment procedure.
The objective of P.γ is to aid the decision maker through a ranking that is obtained by placing all, or simply the “most attractive,” actions into equivalence classes that are completely or partially ordered according to preferences. P.γ results in a ranking or an ordering procedure.
The objective of P.δ is to aid the decision maker by developing a description of the actions and their consequences in appropriate terms. It results in a description or a cognitive procedure.
In Section 6.2 we discuss how the problematic chosen for a given phase of the analysis can correspond to one of the four reference problematics, to a sequence of two or more of the problematics, or to a mixed problematic. We illustrate the last two cases with new examples.
