Modélisation de la Structure Complexe des Faits et des Mesures

Overview & Synopsis

Decision support system (DSS) goal is to help decision-makers. They are modeled mainly in a multdimiensional way, that means activity analysis subjects, called facts, with their measures are represented as the center of a star with dimensions and their parameters around. Several models have been devoted to DSS representation, but they handle only relationships between dimensions and their parameters. Recently, some relationships between facts have been analyzed. Relationships between measures indicate correlations through a given activity because they represent properties of this activity. However, there is no work on these relationships. Therefore, we model facts and measures such as relationships between these concepts. We define a UML-based model because it allows a representation related and adapted to DSS terminology and it is well-known by a large amount of designers.
