PRODUCTION SCHEDULING IN A HOLONIC MANUFACTURING SYSTEM USING THE OPEN-CONTROL

Current advances in information technology and electronics allowed the passage from the classic centralized control approach to a fully decentralized control approach. In this context the paper proposes a new control concept in which the commands from a superior control levels are sent as recommendations and low level entities communicate between them in order to solve and optimize the task given as a recommendation. After introducing the control concept, an implementation aiming at production scheduling using a holonic approach is illustrated. The implementation was done on a job shop type production system containing multiple networked workstations.
