Transformations of Knowledge Sources in Decision Support System

The article presents the organization of information structures for the needs of a complex, multi-faceted (multi-methodical) decision analysis, the subject of which is a certain category of objects. The focus is on the discussion of the transformation of the information structure of partial mathematical models, reflecting the objects of analysis, to the form of records of the database and on their connection into a more complex structure, so-called multi-model, in order to subject the method of multi-criteria optimization to calculations. There was also mentioned the possibility of transformation of these complex structures from data records to a simple, tabular form transferred on the inputs of method: AHP, Electre Tri, econometric analysis and induction of decision rules.
