Modeling with petri nets and implementation with grafcet of a flexible manufacturing system with concurrent processes and shared resource
Abstract
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.Downloads
