A new approach to study selected functional properties of manufacturing systems based on the concept of orthogonal functional abstractions

In this paper, we introduced a concept of orthogonal functional abstractions. The orthogonal functional abstractions represent selected external functional behaviour of Petri net models. By using orthogonal abstractions which represent one specific aspect of the external behaviour of Petri net models constituting a model of a system, the selected functionality of the whole system can be studied in separation from other functionalities. This allows one to study paths of flow of major resources in the system. In addition, the correctness of the interfaces between the constituent components of the system can be studied as well.
