Abstract: We continue the analysis of the notion of information in a two-stage
decision process. In the previous work and in the present one, when examining
specific concepts and types of information, we achieve a better understanding
of mathematical contents of the notion. Only elementary set-theoretical tools
are used. All the formalism previously introduced is largely used here; it is
shortly recalled here. We try to formally approach several concepts: uncertainty,
measurement and prediction, often applied in decision-making theory. Then,
after introducing the notion of independent information, we attempt to
formulate a precise definition of what we understand as decision making
problem.
Keywords: decision variant, basic form of information, informational set, uncertainty, independent information, decision making problem
