Modeling of production processes using UML and Petri nets.

The paper proposes combined use of UML and Petri nets to model production processes which will be useful for designers of production processes in any area of industry. In practice, the specification of a normal operation cycle is presented by a technical drawing. It is known that UML helps to present the concept and various aspects of a system, and Petri nets can provide information about faults. A major challenge in modeling a production process with dynamic models of activity diagrams such as UML 2.0 and PNs is cooperation of these two different methods and conversion between them. The meta-model can be used to control the effects of modifications made in the system. These methods have been widely applied in different areas, but being applied together they can produce new results. This will be demonstrated on a practical example.
