Abstract: The model of Elementary Object System is introduced and motivated by several examples and applications. Object systems support a modeling of systems by Petri nets following the paradigm of Object-Oriented Modeling. They are composed of a System Net and one or more Object Nets which can be seen as token objects of the system net. By this approach an interesting and challenging two-level system modeling technique is introduced. Similar to the object-oriented approach, complex systems are modeled close to their real appearance in a natural way to promote clear and reliable concepts. Applications in fields like workflow, flexible manufacturing or agent-oriented approaches (mobile agents and/or intelligent agents as in AI research) are feasible. This paper gives an introduction with several examples, but only few definitions and no theorems.
