Abstract: Argumentation systems are useful instruments for decision support when the arguments are changed dynamically in dependence of the users and the situation. In argumentation systems different strategies are used when the system prepares the argumentation for a given situation and/or user. These strategies correspond to some many valued logics and some of these strategies have fuzzy and rough interpretations. Many information systems have interpretation in different argumentation systems. For the lower and upper approximations there are equivalent argumentation strategies that correspond to the well known logical systems. Moreover when a practical system chooses the arguments for the user it needs more compact argumentation then the list of all procedures it uses. Then the argumentation system finds arguments with the same persuade power as its argumentation.
