    In order to facilitate modeling of complex hierarchical and dynamically structured concurrent systems this paper proposes extending high-level Petri nets with parametric and dynamic net structures based on a Petri net component concept. It proceeds to show how to apply ...
    Abstract— The process of designing complex manufacturing machines involes problems of interdisciplinary communication, design space exploration as well as design evaluation and analysis that can best be solved by integrating modeling and... more
    Abstract— The process of designing complex manufacturing machines involes problems of interdisciplinary communication, design space exploration as well as design evaluation and analysis that can best be solved by integrating modeling and simulation stages into the development ...
    Efficient simulation of Petri net models is a key factor for the utility of this modeling formalism for real-world problems. Their locality and high degree of concurrency makes them candidates for parallel and distributed execution. An... more
    Efficient simulation of Petri net models is a key factor for the utility of this modeling formalism for real-world problems. Their locality and high degree of concurrency makes them candidates for parallel and distributed execution. An important condition for efficient distributed ...
    Since computation in multimedia systems is often stream-oriented, it is often best represented as a dataflow program, which accounts for the growing popularity of dataflow in these application areas, eg [1]. Due to the very different... more

    Petri nets are an established and well researched means for systems modeling and simulation, but its use in the engineering community is not as widespread as the applicability of the formalism would suggest. A reason for this might lie in... more
    Petri nets are an established and well researched means for systems modeling and simulation, but its use in the engineering community is not as widespread as the applicability of the formalism would suggest. A reason for this might lie in the fact that there is no ...
