Formal validation of complex production systems using coloured Petri nets

Petri nets have been proven to be specially adequate for modeling parallel and distributed systems such as flexible manufacturing systems. Moreover, they have a well-founded theory of analysis that allows for investigating a great number of qualitative properties of the modelled systems. In order to validate complex production system models with this tool, this work proposes a formal technique for qualitative validation of the system´s specifications, based on the place-invariants of its coloured Petri net models. One example taken from the literature on FMSs is modelled by coloured Petri nets and analyzed by the proposed formal validation techniques
