Combining Supervisory Control, Object-oriented Petri-Nets and 3D Simulation for Hybrid Simulation Systems using a Flexible Meta Data Approach

摘要

The idea of Supervisory Control is to regard a control component (Supervisor) as a discreet event simulation. State Oriented Modeling combines the ideas of supervisory control and object-oriented Petri-nets. With these concepts as a starting point, our goal was to realize a truly hybrid simulation system, which allows the simultaneous use of discreet event simulation and continuous 3D-simulation on a unified database. The key component is an active real-time simulation database, which is an object-oriented, self-reflecting graph database, with a powerful meta-information system. All nodes are derived from a common base class and data is stored in properties with standardized getter and setter functions. The object-oriented Petri-nets are formally described in the State Oriented Modeling Language, which is itself an extension scheme of the simulation database.
