From centralized to distributed models: A systematic procedure based on Petri nets

In the field of manufnchlring systems, a distributed workshop can fsoilitate the dynamic monfiguration of flexible production lines. Differcot modeling techniques exist to describe discrete events sod numerous rescarehers propo3e advanced methods and toob to analyze or to build the production line modeh In this paper, we propose a method to transform a Petri net bared cenlrdiied model of control and supervision Into a modular one. A protocol of communication is propose to mintaim the coherence behwen distributed data and decisions.
