Aspects Regarding the Modeling of Intelligent Manufacturing Systems by Using Grafcet

摘要

The implementing of a Flexible Manufacturing System in an integrate production system, represents an important result, which leads to the optimization of the entire material and informational flux of the enterprise. In this paper were developed management and control models of system in real-time, using artificial intelligence techniques. The simulation of the proposed manufacturing system using timed Grafcet provides the possibility to view the manufacturing process in time. Are described the applications of Grafcet to monitoring and control, knowledge-based applications. Aided by the simulation models designed one have studied: the influence of changes in the system structure on its behavior; influence of commands evolution and of system states on its output; influence of initial conditions or of some parameters on FMS behavior etc. Thus, we have been able to explore continuously ongoing operations, new operation procedures, decision rules, and information flows, material flows for the intelligent manufacturing system studied through simulation.
