CASTELLANOS ARIAS, Johanna Stella  e  SOLAQUE GUZMAN, Leonardo Enrique. MODELING WITH PETRI NETS AND IMPLEMENTATION WITH GRAFCET OF A FLEXIBLE MANUFACTURING SYSTEM WITH CONCURRENT PROCESSES AND SHARED RESOURCES. Cienc. Ing. Neogranad. [online]. 2010, vol.20, n.1, pp.61-75. ISSN 0124-8170.

This paper shows a model of Flexible Manufacturing System (FMS) with concurrent processes and shared resources based on Discrete Event Systems through Petri Nets (PN) and GRAFCET. FMS is represented by a hypothetic model that is modeled by a PN to identify its dynamic and achieve the optimal system sequence. A mathematical model was developed to find the time accumulated vector for processes in a system modeled by PN. Using this vector it is possible locate the best system sequence. Finally, in order to simulate the FMS modeled, an electro-hydro-pneumatic assembly controlled by GRAFCET through PLC was implemented in Automation Lab at Universidad Militar Nueva Granada.
