Hierarchical Object Nets - a Methodology for Graphical Modeling of Discrete Event Systems

In this paper we introduce Hierarchical Object Nets as a modeling methodology for discrete event systems based on the DEVS (Discrete Event System Specification) formalism. We explain the modifications we propose and show how the methodology may serve as a basis for an open visual object-oriented modeling and simulation system. Further, the advanced concepts of active simulation objects and the prototype oriented model base are explained. The advantages of the concept for modeling, simulation and evaluation are reviewed.
