R. Tawegoum et al., HIERARCHICAL AND DYNAMIC PRODUCTION CONTROL IN FLEXIBLE MANUFACTURINGSYSTEMS, Robotics and computer-integrated manufacturing, 11(4), 1994, pp. 327-334
Job shop control involves directing the Row of products through the ma
nufacturing system, Centralized and decentralized approaches have been
proposed. This paper introduces first a mix approach in the organizat
ion of real time control level in flexible manufacturing systems: a hi
erarchical organization permits coordination of distributed decision c
entres and heterarchical consideration confers a partial autonomy to s
ub-level decision centres. Second, corrective actions against unexpect
ed events are introduced to maintain as far as possible the forecasted
scheduling.
