Simulation Based Design of Control Systems Using DEVS and Petri Nets

摘要

Current model-based design methodologies use executable semi-formal models allowing for transformations including code generation. Nevertheless, the code should be finalized manually and further development or debugging by means of prime models is impossible. The paper introduces an approach to the system design called Simulation Based Design which uses fromalisms of DEVS (Discrete-Event Systems Specification) and Object Oriented Petri Nets (OOPN) allowing for clear modeling, a possibility to check correctness by means of simulation as well as by formal verification. The approach is based on techniques such as incremental development in the simulation, reality-in-the-loop simulation, and model-continuity. The model is understood as an executable program valid through all development stages including the deployment (the target system).
