THE APPLICATION OF ENHANCED MARK FLOW GRAPH IN REAL TIME CONTROL SYSTEMS

摘要

The aim of this work is the evaluation of the modeling power of Enhanced Mark Flow Graph (E-MFG) when dealing with flexible manufacturing systems and the presentation of an approach to link the models to the real system. Main concepts regarding E-MFG and its application in the description of the control part are described as well as the operative part of production systems. Through the information associated with the structural components of E-MFG it is possible to represent complex control strategies involving different tasks of the manufacturing systems in a highly flexible environment. An object oriented approach for integrating the various heterogeneous controllers available in a manufacturing system is presented, resulting in an abstract machine that realizes the operative part and, thus, ensures the link between the E-MFG models and the physical system.
