MANUFACTURING SYSTEM MODELING USING PETRI NETS

Abstract. This paper presents the modeling and simulation of a manufacturing system using Petri nets. A manufacturing system consists of robots, computer-controlled machines, numerical controlled machines, computers and automated guided vehicle. Timed Petri nets are used to model, simulate and evaluate the manufacturing system. The Petri net model is implemented in Petri Net Toolbox under MATLAB environment. It is achieve the graphic construction of the net. Then, transporting it into a specific mathematical formalism it is made, so that the fulfilled structure to be fully retrieved and used to bring out the internal dynamics of the model. There are determined the global performance indicators in order to evaluate the performance of the manufacturing system
