Systematic construction of functional abstractions of Petri net models of typical components of flexible manufacturing systems

The use of generic models in the synthesis of FMSs, which allows for rapid modelling and analysis, does not reduce complexity of the verification model. This complexity can be reduced by replacing the constituent components (generic models) with their functional abstractions, which represent the external behaviour of the components. In the paper, for a class of Petri net models representing primary components of FMSs, a method that allows to systematically construct functional abstractions is presented. This method is then used to obtain the functional abstraction of the Petri net model of a machining station
