Object Oriented Petri Nets Modelling Techniques Case Study

The importance of models used in the area of system design is growing. There were investigated and developed many methodologies of system design based on models -- they are known as Model-Based Design. These methodologies use semi-formal models and need for model transformations to check correctness or to get a final application. Formal models, by contrast, allow for clear modelling and checking correctness by simulation techniques as well as by formal verifications. The model is an executable program valid through all development stages including the target application. There are several suitable formalisms, one of them is a formalism of Petri Nets, especially its object variant, Object Oriented Petri Nets (OOPN). The paper deals with application of OOPN formalism in the area of system design and demonstrates modeling techniques of OOPN on the case study of conference system design.
