Keywords: Systeme, dynamische; Petrinetze; Granularität; Abstraktion; Modellierung; Logik, lineare; Typ-Theorie; Verifikation; Objektorientierung; Agentenorientierung; Strukturdynamik

Objectives: Verschiedene theoretische und praktische Ansätze zur Modellierung von statischen und dynamischen Systemstrukturen wurden auf ihre theoretische und konzeptionelle Angemessenheit hin gegenübergestellt. Erklärtes Ziel ist es, dynamische Strukturen auch durch dynamische Petrinetzstrukturen adäquat zu modellieren.

Insbesondere der Formalismus der Referenznetze und Objektpetrinetze werden auf formaler Ebene untersucht, wobei fundamentale Eigenschaften von gewöhnlichen Petrinetzen auf diese Formalismen übertragen werden konnten. Referenznetze bieten die Möglichkeit, dynamisch ein System von sich gegenseitig referenzierenden Netzen umzustrukturieren. Objektnetze liefern fundamentale Aussagen zu geschachtelten Systemen.

Im Vordergrund standen zustands- und prozessorientierte Konzepte sowie das Konzept der Mobilität. Diese grundlegenden Konzepte wurden verstärkt vor dem Hintergrund der Agentenmodellierung und der Modellierung soziologischer Theorien untersucht. Ein weiterer Bereich war die Untersuchung von Team- und Planungskonzepten für die dynamische Anpassung von Agentenverhalten. Des Weiteren wird der Begriff der Organisation im Hinblick auf spezielle Muster von dynamischen PN-Strukturen diskutiert.
