Architecture of autonomous distributed manufacturing systemAutonomous functions of individual components of the manufacturing system are discussed and analyzed from the viewpoint of decision making, communication and control functions. It was clarified, through the analysis, that the cooperation between the autonomous manufacturing equipment and the autonomous workpieces play a key role in the design and management of the autonomous distributed manufacturing systems.2. Development of simulation systems of the autonomous distributed manufacturing systemsSimulation systems have been developed based on the object oriented model in order to represent the cooperative function among the autonomous elements in the manufacturing systems and to simulate autonomous controls of the manufacturing systems. Two types of simulation systems have been developed for both the batch type production of mechanical products and the line type production of the composite parts for air crafts.3. Application to autonomous real-time schedulingReal-time scheduling systems have been developed based on the models proposed 2. It was clarified, through the simulations, that the autonomous real-time scheduling methods are effective to determine suitable schedules for the individual equipment and workpieces in the manufacturing systems.
