Hybrid High-level Nets

This paper presents a new methodology for modeling and simulation of hybrid systems which is called Hybrid High-level Nets (HYNETS). The new methodology integrates three established modeling approaches into one language. High-level Petri Nets represent the basic discrete framework, differential algebraic equations (DAEs) are used to describe continuous systems behavior and object-oriented concepts improve the expressiveness and compactness of models. The paper explains basic ideas of the language and illustrates its usefulness with a small example.
